Description
ANTITUMOUR PHARMACEUTICAL COMPOSITIONS AND PROCESS FOR PREPARING THE SAME
Technical field
The present invention relates to antitumour pharmaceutical compositions and process for preparing the same. Another object of the present invention is the use of certain polyamine derivatives having a molecular weight of not higher than 800 in the therapy of diseases connected with cellular proliferation.
Background art
Compounds of the general formula
are known in the literature and used in many different industrial fields. Thus, e. g. N-[2-[2-/heptadecenyl/-2-imidazolin-l-yl]-ethyl]-oleamide is known from GB Pat. No.929397 as additive for polyepoxydbitumens . J. Chem. Res. Synop. 1981/3/ 84-5 and DE-OS No.2546180 disclose the reactions of different steric isomer of N-[2- [2-/8-heptadecenyl/-4,5-dihydro-1H-imidazol-1-yl]-ethyl]-9-octadecenamide and the use thereof in the floatation of Nb/Ta minerals. The article of Przem. Chem.46/8/, 479-81 describes the
/1:1 / mixture of N,N’-[ethylenebis/iminoethylene/]bis/9,11-octadecadienamide/ and -/9,11-octadecadienoate/ and the use thereof as cationic surfactant. According to US Pat. No.3337459 N,N’-[pninobis/ethyleneiminoethylene/]bis/10-octadecenamide/ is used as lubricant. US Patent No.31934-54 describes 1,1′-/iminodiethylene/bis[2-/8-heptadecenyl/-2-imidazoline as additive for paints .
There is, however, no reference at all in the prior art to any therapeutical effect of the aforementioned compounds.
The last 100 years brought basic changes in the human environment, especially as a result of the extraordinary development of chemistry. Of course , this development started in unfavourable phenomena as well, and one of these is the rapid increase of tumorous di seases .
At present, cancer research is one of the most developing research areas and needs extraordinary financial and mental supply. Besides basic research, there are great efforts in the therapy of certain specific types of tumorous diseases . In many cases, chirurgical intervention is often accompanied by other kinds of therapy, e. g. irradiation, chemotherapy, etc. The known processes and especially chemotherapeutic methods have the common characteri sties that they are limited in the field of specific types of tumour. No general method resulting in a general regeneration of tumorous cell has been found s o far.
According to the present state of science, tumorous disease s can be cured when detected in the very early state. As the early pha se is very hard to recognize , tumorous diseases belong to thαse which are the most difficult to cure. Generally, symptomatic treatment is performed but the recovery rate is very poor. Therefore, there is a strong need for therapeutic agents which prevent the occurance of tumorous diseases and provide general and appropriate therapeutic effect in case of developed disease at the same time .
Disclosure of Invention
The aim of the present invention is to provide pharmaceutical composition which fulfills the above conditions . There is also provided a process for preparing the same pharmaceutical compositions .
A further object of the present invention is the use of the compounds of the general formula /I/ as above in and for the therapy of tumorous diseases .
The invention is based on the recognition that the reason of starting of cancerous processes is due to failures in the correct information and /or circulation chain between cells. In healthy organ, permanent communication takes place between the cells. The occur ance of malign processes in the organ is a result of lack of «communication channels» between cells , as the cells cannot recognize each other, lose their connections and start to multiply according to their own internal information. The multiplication is of malign degree and leads to proliferation.
It has been found that the proliferated cells having occured due to malign processes are not to be destroyed, but the possible contact between these and /or healthy cells should be re-established.
The only way to re-establish the tissue structure of tumour cells into healthy tissue is to renew the intercellular communication.
Presumably, the protein shell occuring on the cell wall forms a shield on the membrane , thus , making the intercellular «communication channels» unable to operate . Starting from this theory, our investigations were directed to find materials which disintegrates the said protein shell so that the intercellular communication channels can recover and the tumor cell loses its isolation.
It has been found that the above effect can be achieved by the compounds of the general formula /I/ as above , wherein
R is longer aliphatic hydrocarbon radical which may contain one or more unsaturation, R1 is hydrogen or longer aliphatic acyl radical which may contain one or more unsaturation, X is oxygen and Y is hydrogen, or
X and Y, when taken together, form a radical of the formula
=N-CH2-CH2- , z is an integer of 1 to 5, q is an integer of 1 to 4.
It can be seen that the above compounds are straight chained polymer amino compounds, as well as the tautomers thereof, when X and Y together form a group =N -CH2-CH2- , i. e . an intermolecular dihydroimidazo ring is formed.
The above longer aliphatic hydrocarbon group contains preferably 12 to 20 carbon atoms and optionally at least one double bond. In the open chained compounds , i. e. wherein X is oxygen, the longer aliphatic acyl group is preferably derived from stearic acid, oleic acid and linoleic acid.
As already mentioned , the compounds of the general formula /I/ are known in the art, or, if novel, they can be prepared by known methods , e. g. by the following reactions:
Of course, the compounds of the general formula /I/ having other structure than the above end products can be prepared by essentially the same routes as described he re above.
In the pharmaceutical preparations of the present invention
any of the compounds of the general formula /I/, as well as the mixture of any or even all of them can be used as active ingredient. Under «active ingredient» all the possible stereoisomers of the afore said compounds are also to be meant. It is to be mentioned that in aqueous medium equilibrium occurs between the open chained and tautomeric ring form.
The pharmaceutical compositions according to the present invention can be prepared by process well known for formulating compositions of this type, such as by mixing one or more compounds of the general formula /I/ with at least one physiologically acceptable carrier.
The pharmaceutical compositions according to the invention can be administered orally or preferably intravenally, another prefe rred administration form being the inhalation. For this purpose , the vapour of active compound according to the invention, or the mixture of more of these or that of the same formulated into inhalation compo sition is inhaled by the patient. In case of inhalation, the vapour phase may contain not only the vapour of the active compounds of the formula /I/ but also some decomposition products . These have the general formula NRR ‘R» and H2N- ∏CRR ‘ / y-NH ∏x-H , wherein
R is hydrogen, lower alkyl or – /CH2/n-OH ,
R ‘ and R» are hydrogen and lower alkyl, and n, x and y are integers .
As possible decomposition product formaldehyde should also be mentioned.
Accordingly, the pharmaceutical compositions according to the invention comprise also the formulations containing the compounds of the formula /I/ and the decomposition products thereof as active ingredient. T he active compounds and the pharmaceutical compositions ,
resp. , accordiαg to the invention induce the tumor cells and normal cells to communicate, consequently, the tumor cells again recognize their environment, further proliferation terminates and the immun system goes into action by eliminating the superfluous , but no more tumorous cells by the aid of different protective mechanisms of the organism. According to our biological tests, a mixture of the active compounds of the general formula /I/ proved to be especially active in re-establishing the inter cellular communication and /or circulation channels . According to the invention, the regeneration or creation of inter .cellular communication and /or circulation channels maybe accomplished both in vivo and in vitro. For these purposes the active compounds and compositions according to the invention, preferably the above mixture are administered via blood flow, lymphatic system, orally and /or b y inhalation technique .
The antitumour effect of the compounds of the general for /I/ and the mixture thereof was tested in animal and clinical experiments as well as in vitro on tissue cultures, including leukemia virus producing transformed cell lines . It has been found that trans formed and malign proliferation cell lines can be brought in contact inhibition with a 10 -5 to 10- 6 dilution of the compounds and compositions according to the invention while the non-malignous lines are not inhibited in their multiplying. During tests carried out on mices the tumour inhibiting dosis of the compounds proved to be less than 100 μg/kg body weight. At the first stage of clinical trials it was established that according to our special diagnostic method described in Hungarian Patent
Application No . 78/84 considerable regeneration from the tumorous state took place.
In the aforementioned dilutions the compounds according to the invention are non-toxic, LD 50 in animal experiments is 15 mg/kg po. and 17 mg/kg when administered in the tumour. In tissue cultures the toxicity is ≤ 5 x 104 dilution.
Our biological tests showed that the compositions according to the invention possess antitumour effect. Accordingly, these compositions are valuable in the therapy of tumorous diseases as well as for regenerating tumorous cells and tissues . These pharmaceutical compositions are not only useful in themselves in the therapy but can also be used to complete other techniques , like chirurgical operations . Moreover, they can complete or prepare the conditions of other treatments .
Example According to the general preparation route as described in the descriptive part, the following compounds were prepared and identified by mass spectroscopy and NMR spectroscopy methods /In the formulae herebelow linolyl group is labelled by L and oleyl is labelled by O . /

The NMR /1H , 13C and 15N / spectroscopy confirmed the above structures .
The above compounds as well as the mixture thereof /in the followings: CDM/ were tested in the following biological arrangements:
In vitro tests were carried out to answer the following problems :
– What is the effect of CDM on the proliferation of cells with or without malignant transformation in vitro . Investigations were first performed on cell lines in the log. phase /logarithmic growth phase ; experiments type A/ , thereafter on cells being in the plateau phase /hardly proliferating cells , experiments type B /;
– Determination of the biologically effective dilution range . The applied doses were not expressed in concentration but in dilutioon units ;
– Investigations of the in vitro cytotoxicity of CDM, and the reversibility of this effect.
The following materials and methods were applied in these experiments : Cell lines
Cell lines of normal tissue origin: McCoy’ s human monolayer cell line of synovial origin,
BHK fibroblast type monolayer cell line of newborn hamst er kidney origin, in BHK-B and in BHK -Tubingen varieties, HAK monolayer cell line of adult hamster kidney origin,
MRC-5 monolayer cell line of human embrional lung origin.
Cell lines of tumour origin: LLC monolayer cell line of human bronchial carcinoma origin /maintainable also in vivo, in mice/ containing 70-80 % epithelioid type cell,
HeLa-S3 a clone of a cell line of human cervical carcinoma origin,
K 562 a cell line of erythroid leukemia origin, growing in suspension, SP 2 a suspension clone of mouse myeloid leukemia origin ,
P-388 a suspension cell line of mouse lymphoid leukemia origin,
L-1210 a cell line of mouse lymphoid leukemia origin /it is maintainable in ascitic form, too/.
Culturing conditions
Cell lines were maintained in Minimum Essential Medium /MEM/ containing 10 % fetal calf serum /FCS , Flow Laboratories Ltd. / . In order to avoid bacterial infection 50 μg/ml gentamycin /SERVA/ was added. The cultures were maintained in 25 cm3 Falcon plastic cell culture vessels /NUNC , Greiner or Costar/ in 10 ml volumes .
Monolayer cultures were transferred with the addition of 0,05 % trypsine , while suspension cultures were diluted. For tests on CDM cell culture multiplates containing 24 wells of 2 cm3 were used with the addition of 1 ml medium/well. The cultures were grown for 72 hours at 37 °C in an atmosphere containing 5 % CO2. Relative humidity was kept at 75-80 %. Cell cultures in log. phase were achieved by tenfold dilution of cultures being in plateau phase and showing contact inhibition. In monolayer cultures , the condition of contact inhibition was considered to occur on day following the microscopic appearance of cell confluence . These cultures were used in B-type experiments.
Dilution of CDM
CDM was diluted in MEM /without serum/, starting from
thousand fold dilution of the stock solution. The proper fine dispersity of the emulsion was achieved by a lasting intense mixing using a Vortex mixer. Before the addition to the cultures the given dilutions were carefully re ogenized.
Cell counting was performed by Bϋrker’ s homocytometer or, if also cytofluorometric measurement was performed out the value s of the Cytofluoro graph were automatically accepted.
Flow-microfluorometric measurements
After trypsinization cells were centrifuged and stained in ice cold isotcnic trisodiumcitrate containing 50 μg propidium-jodide for 30 minutes . Measurements were performed using a Cytofluorograph /Bio /Physic Inc. / with the aid of an Ar ion gas laser at 488 nm. The fluorescence of propidium-jodide -DNA complex was detected above 600 nm. By means of a built-in electronic differential discriminator, cells having less than «diploide» DNA content were discarded, because these cells very probably died long before the measurement.
Determination of viability
After trypsinization cells were suspended in MEM medium containing 0, 05 % w/v trypan-blue stain. Five minutes later the number of living /excluding trypan-blue/ cells and dead cells /becoming blue / was determined by light microscopy.
Determination of reversibility
Cell cultures were treated for 24 hours with CDM . At this time half of the parallel samples were analysed, while the rest was re-incubated in a fresh medium containing no CDM. After 24 hours recultivation was stopped and the cells were removed for analysis .
RESULTS
CDM was first investigated on log. phase cell cultures .
Optimal dose range for further studies was selected on SP 2 cell line, where CDM was applied at a wide concentration range.
On the basis of these experiences in further works a dilution range of 5 x 104 – 107 -fold was used. According to the modification of the growth curves, our test systems can be groupped as follows:
– 5 x 104 -fold dilution of CDM killed the cells of the culture by the 24th hour /K-562, MRC-5, BHK-B , McCoy, HAK , SP 2/; – 5 x 104 -fold dilution of CDM killed the cells of the culture by the 48th hour of experiment /P-388, L-1210, BHK-Tϋb. /;
– no detactable toxic effect at the investigated dilution range /HeLa, LLC/. Certain concentrations of CDM even stimulated the growth of cells of the two later lines being in the log. phase .
The effect of CDM on cultures being at the contact inhibition phase was investigated in two series . It was found that the effects of CDM were reversible in dilutions over 105 -fold, while in dilutions under 104 -fold it seemed to be irreversible . One part of the growth-response curves, registered after a 72 hour culture period showed a continuous change /BHK-B , BHK-Tüb. , HAK , L-1210/, while others had a local minimum point /SP 2, McCoy, LLC , HeLa, MRC-5, P -388/. Most of the local minimum points were within the 105 – 106 -fold dilution range.
Viability studies were performed on four cell lines /LLC, McCoy, HeLa, BHK-T üb. / at a dilution range of 5 x 103 – 106. In
104 -fold or lower dilutions CDM resulted in 100 % toxicϊty. The in vitro LD50 values fell between 104 and 5 x 104 -fold dilution.
In further tests , the leukemia virus producing QL transformed cell line /Nagy, K . : Chester Beatty Seminars /London/ 1983/ was chosen to study the effects of CDM in vitro.
Materials and methods
Because of the alkaline nature of the material COM was not applied directly, but first diluted in dimethylsulfoxide /DMSO , Reanal/ and its further dilutions were used.
Cell culture
The transformed quail fibroplast cell line /QL / continuously produce MC 29 /L virus subline of increased oncogenicity.
Cells were maintained and propagated in Falcon-type plastic culture flasks . Parker 199 tissue culter medium completed with 10 % tryptose-phosphate , 5 % fetal calf serum and 1 % chicken serum, was used. Cell cultures were incubated at 37 ºC in an atmosphere containing 5 % CO2 in air. Cell cultures were transferred by trypsinization usually every other day.
Cell counting Cell cultures were dispersed by trypsinization and the cell counts were determined by a Laborscal /Labor MIM/ electronic cell counter or in a few cases , using the conventional Buerker’ s method.
Viability Cell counts were corrected according to the proportion of living cells . This was determined using the trypan blue exlusion technique.
Determination of 3 H-thymidine incorporation
The rate of DNA synthesis was determined after CDM treatment by means of the addition of 50 μCi /0,2 ml/ radioactive 3Η-thymidine nucleoside /Thymidine-6-3Η , Chemopol, Czecho-Slovakia/ to the cultures /106 cells vessel/ .
At selected intervals cell suspensions were washed with culture medium and after centrifugation /2000 rpm, 5 min. , +4 ºC / cells were precipitated with 5 ml 5 % ice cold trichloroacetic acid and collected on Millipore filter. The radioactivity of the samples were
determined using Packard Tricarb scintillation counter.
Reverse transcriptase /RT / assay
In the culture medium of QL cells the presence and titer of the MC 29 /L virus was determined by the RT enzyme activity characteristic only to RNA tumour viruses . Culture medium was first cleared from cell debris by centrifugation /10000 g, 30 min. , +4 ºC /. Virus fraction was then concentrated by ultra-centrifugation /100000 g, 90 min. , +4 °C/; /MSE 65 Super Speed, U.K . /.
Sediment was resuspended in the following buffer solution: 0,01 M Tris-HCl pH 7,5, 0, 1 M NaCl and 0,001 M EDTA. The reaction was carried out as described earlier in Acta Microbiol. 25 , 142 /1978/. Briefly: reaction mixture containing TKD buffer, MnCl2 Triton -X 100 and thymidine-triphosphate was incubated with poly /rA/ /dT/12 template-primary in the presence of the virus. The synthesized DNA was precipitated by TCA on filter discs and their activity was determined by a scintillation counter .
Immunofluorescence
The state or alterations of active filaments, which build up the skeleton of the cell – cyto skeleton – were studied by indirect immunofluorescence in normal, transformed and CDM treated cells . Cells were grown on thin round cover glasses and incubated with anti-actin rabbit serum at 37 °C for 40 minutes . After abundant washing incubations continued with second antibodies , either with fluorescein or with rhodamin conjugated anti-rabbit goat serum. After the second antibody conjugation samples were examined by fluorescence microscopy, in ultraviolet light.
Toxicity test
Two days old of QL fibroblast cultures containing 106 cells were treated with various concentrations of CDM diluted in DMSO.
The diluted material was added to the vessels in one ml volume . 48 hours later cell count and viability were determined. Toxocity test revealed, that 103, 104 and 105 -fold dilutions of CDM were highly cytotoxic, since they decreased significantly the number and viability of living QL cells . Even the 106 -fold dilution resulted in cell count decrease, although it was not significant. There was practically no decrease in cell count or viability at 107 or higher dilutions , so these dilutions can be considered as non-toxic for QL cells .
Inhibition of cell proliferation The effect of CDM was studied on the kinetics of rapidly proliferating transformed QL cells. Untreated cells doubled their number every second day.
Cell proliferation was highly influenced by the various concentrations of CDM. The 107 -fold dilution did not alter the characteristics of the proliferation, h owever, longer time was needed to produce the same number of cells as compared to controls . The effect of the
106 -fold dilution is interesting. Cell-division started slowlier, but its intensity was constant until the 6th day. From that time the proportion of divisions increased and on day 8 it was close to the value of the former dilution. The effect of the 105 -fold dilution was opposite . First a slow proliferation started, but it stopped on day 4 and from this day on the cell count gradually decreased. The 104 dilution resulted in this effect already on the second day of treatment.
Intensity of DNA synthesis
The intensity of DNA synthesis was measured by the incorporation of a radioactive nucleoside-thymidine into proliferating treated and untreated cells . Day by day increasing incorporation was found in untreated cells. The rate of increase was diminished on the days 5, 6. At 107 -fold dilution a variable degree of increase and decrease
of thymidine incorporation was observed, nevertheless it showed still an overall slow increase . 106 dilution moderately decreased the intensity of DNA synthesis of QL cells while 105 -fold dilution caused a very considerable decrease .
Reverse transcriptase assay
Besides studying the effect of CDM on the intensity of
DNA synthesis and cell proliferation we wanted to study the influence of the compound on the propagation of tumour viruses produced by QL cells . On the indicated days samples were taken from the culture media and reverse transcriptase enzyme activity, characteristic to tumour viruses , were determined. 107 -fold dilution of CDM decreased the enzyme activity which is proportional to virus concentration, as compared to untreated cells, but the values showed an increasing tendency in the function of time. At 106 -fold dilution, there was a certain initial increase but it declined on day 6 /3rd measurement/ and measurements revealed a strongly decreased virus concentration. 105 dilution completely inhibited virus propagation, on the sixth, and eighth days there were no enzyme activity detectable . Alteration of cytoskeleton actin filaments
The skeleton of superior cells is the cytoskeleton. This is a complex network of protein filaments in the cytoplasm. The main constituents are actin filaments . The presence and alterations of them were investigated in normal, virus transformed and CDM treated fibroblasts .
In normal fibroblasts they form strong, organized fascicles, these actin fascicles can be observed all over the cytoplasm. Cells transformed by ONCORNA viruses show a totally different morphological appearance. In these cells actin filaments become fibrillous, they may
form knots, they are situated irregularly without any order, and might be present or missing in any parts of the cytoplasm.
After CDM treatment cells had again a distinct morphological appearance and had outgrowthes . The formerly broken precipitated actin particles were organized into filaments , though the orientation of the filaments was not so expressed yet as found in normal cells . For the sake of more complete demonstration the actin filaments of cytoskeleton were stained with rhodamin, instead of fluorescein, and basically similar process was demonstrated. The pharmacological effect of CDM was tested on Swiss white mice inoculated with tenfold dilution series of Nemeth-Kellner lymphoma /NKL/. The groups of mice were inoculated with the dilutions of NKL and the CDM material at the same time , at the start of the experiment. The animals were then treated with CDM during the test for 5 additional occasions . The animals serving for control were injected with dilutions of the NKL material at the start. These animals were not treated otherwise .
The average weight of CDM treated and control animals were compared six times during the experiment. The average weight of CDM treated animals on the 16th day was by 8 to 27 % less than that of the control.
On the 18th day the animals were exterminated and dissected. In case of mice inoculated with undiluted NKL /50 million cells /animal / CDM did not inhibit the tumour formation. On the groups inoculated with 5 x 106, 5 x 105 and 5 x 104 or less cells , resp. , CDM provide a protection of 20 %, 80 % and 100 %, resp.
