Definitions
- the subject of the invention is new derivatives of bistramides, their production and their therapeutic applications.
- the bistramids are thus called by analogy with a marine organism from which they can be extracted, namely the sea squirt Lissodinum bistratum which lives in symbiosis with its prochlorons.
- bistramides have already been described. These are in particular the bistramides A, B and C. Their complex chemical structure has only been elucidated recently (see article by Foster et al. In J.A.C.S. 1992, 114). It corresponds to the following formula (A):
- bistramide C The interest in these products results, in general, from the strong cytostatic activity which they exhibit in particular in vitro. However, their high cytotoxicity and toxicity in vivo do not make it possible to envisage the use of their properties for uses as medicaments.
- the LD50 of these bistramides is in fact of the order of 1.7 mg / g (measurement on the mouse, after injection of the product intravenously in a single dose).
- bistramides have an cytostatic effect in vitro and therapeutic effects in vivo, but that, unlike the bistramides mentioned above, their cytotoxicity and their toxicity in vivo were much weaker, even non-existent, authorizing their use in therapy.
- the invention therefore aims to provide new derivatives having a structural skeleton of the bistramide type.
- the invention also relates to the biological and biochemical applications of these new bistramides, in particular for the therapy of cancers, in particular, of solid human tumors, or the treatment of parasitic diseases.
- the bistramides of the invention are characterized in that
- LD50 is greater than 30 mg / kg, or even 160 mg / kg or more
- -Ri, X, Y and R2 identical or different from each other, represent a hydrocarbon chain of 1 to 20 carbon atoms, saturated or unsaturated, substituted by at least one -OH group and / or a ketone function, comprising,
- R3 and R4 and R5 are chosen from hydrogen, alkyl or alkoxy radicals of 1 to 4 carbon atoms, a group -COOH, -OH, -NH2 or -NO2, or a halogen atom, it being understood that, when R3 and R4 each represent a hydrogen atom, Ri and R2 do not represent chains respectively
- CH3 - (CH2) 2-CO-CH2 and (CH3, OH) CH-C (CH3) or.
- anti-tumor activity in vivo means that an inhibition of the tumor proliferation of non-small cell bronchopulmonary cancers (80% of pulmonary tumors) has been demonstrated, without acute toxicity for 'animal.
- the "LD50" of the products of the invention was measured on the mouse after injection of the products intravenously.
- bistramides A, B, and C mentioned above are excluded from the scope of the invention. It will also be noted that, because of their high toxicity, these bistramides A, B and C could not lead, during the duration of a treatment, to obtaining the advantageous effects observed with the products of the invention.
- the therapeutic index reaches a value of 5.0 for some of the bistramides of the invention.
- bistramides of the invention are also characterized in that they are capable of exerting cytostatic activity with respect to parasites.
- Ri contains from 1 to 15 carbon atoms.
- Ri has one or two ethylenic double bonds.
- R2 preferably comprises from 6 to 10 carbon atoms, in particular 8 or 9, and advantageously comprises an ethylenic double bond.
- X and Y contain from 2 to 8 carbon atoms, in particular from 2 to 6 carbon atoms, in particular from 3 to 5.
- R3 and R5 advantageously represent, in any one of the preceding arrangements, an alkyl or alkoxy radical, in particular from 1 to 4 carbon atoms, and R4 a hydrogen atom.
- the invention also relates to the derivatives of the bistramides of formula I, more particularly those allowing their use as prodrugs.
- examples that may be mentioned are esters and ethers, in particular alkyl ethers of 1 to 4 carbon atoms, or glycosylated derivatives.
- bistramides taking into account the advantage of their in vivo therapeutic properties which will be explained in the following description, are chosen from - bistramide D, of formula (II)
- bistramides can exist in a dehydrated form.
- bistramide D by hemisynthesis from the bistramide A whose ketone function ⁇ , ⁇ -unsaturated in position 4 is particularly reactive and can be hydroxylated by reaction with a reducing agent. Modifications of the substitution chains can then be made by operating according to known methods.
- bistramide A from ascidia is of the order of 0.1%, while it is only 0.021% for bistramide D.
- the reduction reaction leads, in equivalent proportion to the two epimers of carbon 4, one of which corresponds to bistramide D. This step is carried out with an average yield of 70%, which therefore amounts to multiplying the amount of bistramide D available by a factor of around 1.7 (or 3.5 for the 2 epimers).
- the invention also relates to bistramides as obtained by extraction from L. bistratum and / or its prochlorons, and the derivatives of these bistramides.
- This extraction process comprises successive fractionations by chromatography from an organic extract of L. bistratum and / or its prochlorons. These splits are carried out by implementing the following operations:
- the nature of the support of the chromatography columns and its particle size, as well as the mixture or mixtures of solvents used are chosen so as to selectively separate in a few steps the biologically active bistramides.
- the first two fractionations are advantageously carried out on silica columns using solvents of the ethyl acetate type, dichloromethane, advantageously added with methanol.
- water is used with solvents of the methanol, dichloromethane or acetonitrile type.
- Elution can be carried out according to a gradient, or alternatively isocratically.
- the fractions as isolated at each stage are also targeted by the invention.
- the organic extract to which this succession of fractionation steps is applied is obtained by the treatment of lyophilized powder of L. bistratum and / or its prochlorons with dichloromethane.
- the prochlorons are obtained from colonies of L. bistratum by sieving a suspension formed by compression of the sea squirts in sea water.
- bistramides according to the process described above is applied to an extract such as 'obtained after freezing, lyophilization and extraction with dichloromethane of the residue separated by sieving.
- bistramides induce an irreversible atypical terminal differentiation of tumor cells, resulting in a arrest of the development of the tumor.
- bistramide A This mode of action, which had been envisaged for bistramide A, could not however be taken advantage of, given the acute toxicity of this product. Its administration during the duration of a repetitive treatment, would necessarily involve the intoxication of the organism treated.
- the slightly toxic nature of the products of the invention for the organism allows the differentiating effect to appear on the stem cells of the tumor tissue, without adverse effects on healthy cells, thus authorizing the establishment of a therapeutic platform for treatment.
- the cytostatic effect of the bistramides of the invention is also exerted against parasites.
- bistramides cause the parasite proliferation to stop during the G1 phase of the cell cycle.
- bistramide D has in vitro anti-Leishmanian activity on L. (L) donovani.
- the invention therefore aims to take advantage of the properties of these bistramides for the preparation of pharmaceutical compositions.
- compositions of the invention are characterized in that they contain an effective amount of at least one bistramide as defined above, in combination with an inert pharmaceutical vehicle.
- bistramide used advantageously constitutes, thanks to the nature of its substituents, such as ethers or esters, a prodrug.
- compositions contain, where appropriate, active ingredients from other drugs.
- active ingredients from other drugs.
- anti-mitotic spindle poison drugs such as vincristine, vinblastine or vinorelbine in the context of anti-tumor applications, or with chloroquine for the treatment of parasitic diseases. They will also be used with advantage in combination with compounds facilitating their assimilation such as sugars such as glucose.
- compositions of the invention are particularly suitable for the chemotherapy of cancers in which few cells are in a state of proliferation. They are thus advantageously usable for the treatment of solid human tumors with slow evolution, therefore very chemoresistant, like 80% of bronchopulmonary tumors and certain colonic tumors, breast tumors and melanomas for which the current therapy does not have any really effective drug.
- compositions can also be used for the treatment of parasitic diseases, such as malaria or leishmaniasis.
- the invention therefore also relates to the application of the bistramides defined above to obtain a medicament intended for use as an anti-parasite. It relates in particular to the use of these bistramides and in particular of those corresponding to formulas (II) to (IV), for developing medicaments for the treatment of malaria, or else of leishmaniases.
- the packaging for sale, in particular labeling and instructions for use, and advantageously the packaging are developed according to the intended therapeutic application.
- compositions of the invention can be administered in different forms, more especially by the oral or injectable route.
- compositions advantageously contain from 10 to 100 mg of active principle per dosage unit, preferably from 40 to 60 mg.
- compositions for injection by intravenous, subcutaneous or intramuscular route prepared from sterile or sterilizable solutions. They can also be suspensions or emulsions.
- injectable forms contain per unit of intake from 10 to 50 mg of active principle, preferably from 15 to 30 mg.
- the dosage usable in humans corresponds to the following doses: thus, for example, the patient is administered 10 to 30 mg / day, in one or more doses for the treatment of bronchopulmonary tumors.
- the invention also relates to biological reagents whose active principles consist of the derivatives of bistramides defined above.
- bistramide derivatives and to the study of their anti-tumor and anti-parasitic activity and with reference to the single figure which represents a growth curve as a function of the time of xenografts lung tumors in nude mice after treatment with bistramides of the invention.
- Lissoclinum bistratum (5900 g) is treated 3 times with dichloromethane, at the rate of 3500 ml of solvent per kilo of lyophilized raw material, at room temperature, and with stirring. The organic solutions are filtered, combined, then evaporated to dryness on a rotary evaporator (temperature 40 ° C). The weight of crude extract obtained is 44.2 g.
- This crude extract is fractionated by low pressure liquid chromatography (silica 60-200 ⁇ m 900 g; ethyl acetate: methanol 93: 7 in isocratic elution, 20 ml / min). This results in 11 fractions, of which fraction 9 which contains the bistramides by reference (6000 ° to 8000 ° ml, 22.3 g) (all the elution volumes mentioned in this process include the dead volume of the column).
- Fraction 9 is treated by high pressure liquid chromatography (Jones Chromatography column 52 x 300 mm, silica 8 ⁇ m, dichloromethane: methanol 95: 5 in isocratic elution at 90 ml / min, UV detection 254 nm and RI, mass injected 3g per cycle).
- three fractions are selected: n ° 1 (521 ° at 720 ° ml, 1004 mg), n ° 2 (1261 ° at 2520 ° ml, 2992 mg) and n ° 3 (2521 ° at 3780 ° ml , 532 mg).
- the intermediate fraction not retained (721 ° to 1260 ° ml) corresponds to bistramide A.
- Lot n ° 2 is purified by HPLC (CEDI column
- bistramide D Tr 22 min
- bistramide D 21.4.10-3%
- bistramide K 3.7.10-3%
- bistramide L 2.9.10-3%.
- Fab (fast atomic bombardment) measurements are obtained on a Kratos Concept II HH device.
- the samples are dissolved in a thioglycerol and a small drop of the sample solution is placed on the copper target of the fab direct insertion probe.
- the sample is bombarded with 7 keV xenon atoms.
- the ions produced are accelerated below 8 kV and the negative ions are detected.
- bistramide D and bistramide K in mass spectrometry ei and fab positive represent the molecular ion minus H2O.
- M-H ions are observed for the two metabolites in the fab negative spectra.
- bistramide K shows that it is an isomer of bistramide D.
- the ascidians are detached from their support, carefully washed with plenty of water to get rid of mud and other debris. They are drained, opened one by one with a knife, pressed by hand, then mechanically in a seawater bath. The suspension in seawater is filtered through increasingly fine sieves (123, 63, 40, 10 and 5 ⁇ m). The prochlorons are retained by the 10 ⁇ m sieve. The algae residue is frozen, lyophilized and extracted with dichloromethane. Obtaining the bistramides from this extract is carried out according to the same process as from the extract of whole ascidians.
- bistramide A A solution of 50 mg (0.07 mmol) of bistramide A in 3 ml of THF is cooled in an ice bath.
- Bistramide A is obtained by operating according to Gouiffes et al. in Toxicon, 1988, volume 26, pages 1129-1136.
- the first fractions contain the epimer of bistramide D (16 mg; 32%). Bistramide D (18 mg; 36%) is then recovered. The total yield of reduced products is 68%.
- the procedure is as indicated above, but replacing sodium borohydride with potassium borohydride. The total yield of reduced products is 72%.
- 53 mg (0.07 mmol) of bistramide A are dissolved in 3 ml of methanol containing 10% acetic acid. After the solution has cooled in an ice bath, 13 mg (0.21 mmol) of potassium cyanoborohydride are added.
- reaction mixture After 4 hours of stirring under an inert atmosphere, the reaction mixture is poured into 5 ml of water + ice, then extracted twice with 5 ml of ethyl acetate. After drying over MgSO4, the solvent is evaporated and the residue is purified by chromatography on a column of silica eluted with a mixture of dichloromethane: methanol (95: 5).
- bistramide D The epimer of bistramide D is first elected (18 mg; 34%), then bistramide D is recovered (21 mg; 39%). The total yield of reduced products is 78%.
- the cytostatic effect of the products at the cell cycle level was also studied by cytofluorimetry.
- phase G1 There is an antiproliferative effect of the products linked to an irreversible blockage in the Gl phase, leading to the death of "non-small cell” bronchopulmonary tumor cells (NSCLC-N6).
- This blocking in phase G1 is followed by a transition to phase G1DT, which characterizes the state of terminal differentiation.
- the cells which reach this G1DT phase produce an intracytoplasmic, antiproliferative substance, of a protein nature, which is the product of the expression of a specific gene, which probably plays the role of an anti-oncogene.
- the antitumor activity of the products of the invention has been studied against solid tumors of the NSCLC type grafted in nude mice (D. Riou, C. Roussakis, JF Biard, JF Verbist: "Comparative study of antitumor activity of bistramides A, D and K against a non-small cell bronchopulmonary carcinoma ", Anticancer Research, 1993, 13, 2321-2334).
- Each mouse received 0.2 ml of a cell solution obtained by mechanical dispersion of approximately 1 g of excised mouse tumor in 4.8 ml of sterile saline solution.
- the tumors grafted subcutaneously were measured over their long length L and their short length 1.
- the tumor growth on day d was calculated by the formula Vtj / Vtjo for each mouse, Vtjo being the tumor volume at the start of the treatment.
- the single figure shows the curves of tumor growth as a function of time (days) obtained with or without treatment with bistramides.
- Each point is the average of the tumor growths of 6 mice
- bistramide K is injected at the rate of 10 mg / kg intraperitoneally, for 16 days, and the bistramide D 5 mg / kg intraperitoneally daily for 16 days; 10 mg / kg intravenously on days 1, 5, 9, 14, and 20 mg / kg intravenously on days 1, 5, 9 , 14.
- the examination of these curves shows that compared to the controls (100%), the tumor growth is established, after 30 days, for the treated animals, at:
- bistramide D (5 mg / kg, PI): 100%
- bistramide K (10 mg / kg, PI): 49%
- bistramide A used under the conditions reported above, is too toxic for an anti-tumor effect to be observed.
- bistramide D 2 g are dissolved in 1000 ml of pyrogen-free physiological solution.
- the solution obtained is distributed, under aseptic conditions, in 10 ml ampoules, containing 20 mg of product per ampoule.
- the rodents the animals used are white female mice, SWISS (IFFA CREDO) weighing approximately 30 grams. The number of mice, distributed by batch is five. 2. the strain
- the Plasmodium vinckei petteri species used comes from the strain 279 BY, (see article Cambie G et al in CR.Acad.Sci.PARIS 310, series 111,183-188). This plasmody performs a schizogonic cycle in 24 hours, synchronously. By the freeze-thaw technique of infected blood, only the merozoite stage resists, the other forms being destroyed. If the merozoites are injected at Oh, we observe successively as the predominant stage:
- TM middle trophozoite stage
- AT elderly trophozoite stage
- the maturation of the parasite in the red blood cell, from the ring stage to the aged trophozoite stage corresponds to the Gl phase of the cell cycle.
- This phase is followed by the multiplication of the parasite, S and M phases of the cell cycle.
- the schizont stage corresponds to the bursting and release of the merozoites.
- the parasitaemia calculation (number of parasites per 100 red cells) is done on a smear.
- Bistramide D is used in these tests in sterile physiological water containing 5% DMSO. This product is injected subcutaneously in the thigh.
- PETERS test To verify the activity of the compound studied, the PETERS test is applied, which constitutes the reference for the screening of molecules with antimalarial activity.
- test A
- test B
- test C - controls on D4: parasitaemia 1.20%
- bistramides of the invention To assess the parasite stage or stages most sensitive to the action of the bistramides of the invention, the effect of these bistramides on each predominant parasitic stage during the cell cycle of a given species of Plasmodium has been studied.
- control batch a merozoite batch, a ring batch, a young trophozoite batch, a medium trophozoite batch and an aged trophozoite batch.
- the parasitaemia delay or patent period is evaluated as the time in days necessary for the parasitaemia to reach 1%.
- bistramide D A selective activity of bistramide D is therefore observed on the middle and old trophozoite stages. According to a preliminary flow cytometry study, murine red cells parasitized by the species
- Plasmodium vinckei petteri show, in the presence of bistramide D, a partial blockage of the parasite at the stage of its maturation. This results in a cessation of parasitic proliferation in the middle and old trophozoite stage.
- This blockage which corresponds to the Gl phase of the cell cycle, is dose-dependent, and is probably linked to atypical maturation of the parasite.
- the objective is to monitor parasitaemia on a daily basis and assess the inhibition of parasitaemia according to the therapeutic scheme adopted for a treatment.
- the morphological modifications of the parasite are highlighted by the parasitic formula, the calculation of the parasitic formula is also done on a smear and makes it possible to evaluate the proportion of each stage: ring, young trophozoite, medium trophozoite, aged trophozoite per 100 red cells.
- the methodology applied is as follows: a) after infestation, three batches of five mice are formed, namely - a control batch, OJ, - a batch known as single-dose, for which a single injection of bistramide D (15 mg / kg), to JO, is carried out on the mouse a batch known as multidose, where the injection of bistramide D is carried out by administering five doses respectively to JO, Day 1, Day 2, Day 3, Day 4 (total dose 15 mg / kg) b) the preparation and reading of the smears is carried out daily for 21 days.
- the percentage of parasitaemia and the percentage of inhibition of parasite development were determined for each batch.
- the parasite is mainly found in aged trophozoite form (93%) in the multidose group and in ring form in the control group.
- the parasite therefore appears to be blocked at the aged trophozoite stage.
