Therapeutic composition based on flavonoids, intended to be used in the treatment of tumours by cytotoxic agents The present invention relates to the use of compounds of flavonoid type in the treatment of cancers by cytotoxic agents.
A cancer is a disorder of the somatic genes, in the course of which genetic dysfunctions worsen as the tumour progresses from the state of precancerous lesion to that of malignant transformation, the cancerous tumour becoming metastatic and often. resistant to cytotoxic medicines. -Despite the very considerable efforts conducted in all the developed countries, in particular through experimental and clinical research programmes, mortality due to the various cancers (solid tumours and haematological neoplasias) remains unacceptably high.
In many countries, cancer is placed second, just after cardiovascular diseases, as the cause of mortality.
In terms of newly diagnosed cancers, the distribution between solid tumours and haematological (bone marrow, blood, lymphatic system) neoplasias shows that 9 cancers out of 10 are solid tumours. Unlike that which is observed in haematological oncology (therapeutic success in 40 to 900 of blood cell cancers), only a small number of advanced or disseminated solid tumours respond to only chemotherapeutic treatments. It is partly for this reason that the overall mortality due to cancer increased in the U.S.A. between 1973 and 1992.
It is not, unfortunately, certain that this tendency may be reversed only by the appearance, alongside the'established ehemotherapeutic arsenal, of novel antitumour medicines such as taxanes (paclitaxel and docetaxel), which interfere with the formation of microtubules (W. P. McGuire et al., Am. Intern. Med., 1989), camptothecin-derived topoisomerase I inhibitors ~ .n ~.r (topotecan and irinotecan), vinorelbine (novel alkaloid derived from the periwinkle), gemcitabine (novel cytotoxic antimetabolic agent), raltitrexed (thymidylate synthetase inhibitor) or miltefosine (first representative of the alkylphosphocholine family). These treatments add, either as a first choice or as a second choice, to the medicines for which the specific activity is now well recognized, such as doxorubicin, cisplatin, vincristine, methotrexate, 5 fluorouracil.
One of the most difficult current problems of anticancer chemotherapy is due to the fact that numerous populations of malignant- -cells exhibit considerable resistance to established cytotoxic substances. Most commonly, this situation results from the existence of multiresistance genes or from the frequency of genetic mutations in certain types of tumour. Thus, the treatment of cancers requires novel approaches which are complementary to those currently implemented, and which are intended to more successfully combat the extension and heterogeneity of the tumour load, and the acquisition of "multi-cytotoxic-drug" resistance.
Among these novel approaches, some are already promising. This is the case of the induction of apoptosis, and the inhibition of tumour angiogenesis and of metastatic processes, not to mention gene therapy or immunotherapy.
. The inventors were interested in a different approach. The objective sought was to make the population of tumour cells more sensitive to reference anticancer treatments, in order to achieve a double benefit:
1) increase the cytotoxic activity and therefore the effectiveness, and 2) decrease the frequency and severity of certain side effects, due to the reduction in dosage which might follow the induction of the increase in the antitumour effectiveness.

a .3.a ,~ _ 3 _ It is this strategy which is behind the_ discovery of an original mechanism caused by substances - which have weak antitumour power, or are lacking this power - but which are capable of inducing a very significant increase in the cytotoxic activity of proven anticancer medicines. This original mechanism comes from the possibility for these substances either to stimulate the recruitment of clonogenic cells within the tumour, making it more sensitive to the conventional treatment with cytotoxic agents, or to inhibit the proliferation of clonogenic cells, thus contributing to the regression of the tumour.
A subj ect of the present invention is thus the use, in the treatment of cancers with at least one antitumour agent chosen from cytotoxic agents, of a compound having activity on the proliferation of clonogenic cells, chosen from flavonoids and in particular the compounds of formula:

this being a formula in which:
- R1, R2, R3 and R4 are chosen, independently of each other, from H, OH, a Cl-CQ alkoxy group and an -OCOR~
group, R~ being a Cl-C4 alkyl group, at least one of the substituents R1, R2, R3 or RQ being other than H, and R2 --_ and R3 possibly forming together a methylenedioxy group, - RS is chosen from H, OH, a C1-CQ alkoxy group and an O-glycosyl group, - R6 is chosen from a cyclohexyl group, a phenyl group and a phenyl group substituted 1 to 3 times with groups chosen from H, OH and a C1-C4 alkoxy group, - and ....... designates either a double bond or a single bond.

~ ,.,::, jf The cytotoxic agents can be used at their conventional dose, and in this case, their effectiveness is improved, or at lower doses given the increase in their antitumour effectiveness.
~i A subject of the present invention is also a composition having activity on the proliferation of clonogenic cells by interfering with the generation of clonogenic cells, either by stimulating the proliferation and recruitment, or by inhibiting the proliferation, comprising a therapeutically effective amount of a flavonoid and in particular of a compound of formula I chosen from the compounds of formula:
i this being a formula in which:
- R1, R2, R3 and R4 are chosen, independently of each other, from H, OH, a C1-C4 alkoxy group and an -OCOR7 group, R7 being a C1-C9 alkyl group, at least one of the substituents Rl, R2, R3 or RQ being other than H, and RZ
and R3 possibly forming together a methylenedioxy group, - RS is chosen from H, OH, a C1-Cq aikoxy group and an 0-glycosyl group, - R6 is chosen from a cyclohexyl group, a phenyl group and a phenyl group substituted 1 to 3 times with groups y 25 chosen from H, OH and a C1-C4 alkoxy group, - and ....... designates either a double bond or a single bond.
A subject of the present invention is also the use of a flavonoid and in particular of a compound of formula I as defined above, for manufacturing a medicine intended to interfere (by induction or inhibition) with the generation of clonogenic cells in tumours during treatment with at least one cytotoxic agent.

i , t~
_ 5 _ In the chemotherapeutic treatment of cancers with cytotoxic agents, flavonoids, and in particular the compounds of formula I, can be administered at the start of the chemotherapeutic treatments, either in a single dosage intake or over several days at the start of these treatments (for example for 5 to 7 days) and, depending on the .chemotherapeutic protocol, at the start of each cycle of treatment (for example for 2 to 5 days) in the course of each therapy.
The compounds of formula I are advantageously administered by infusion (generally in 1 to 3 hours) at doses of 5 to 50 mg/kg/day or 200 to 2000 mg/m2/day.
In order to obtain a maximum- effect on the production of clonbgenic cells, the flavonoids should be administered such that the tissue concentrations obtained are as high as conceivably possible.
For protocols of treatment in the acute phases of therapies, the intravenous route is to be favoured uslna:
- ready-to-use infusion solutes (bags, bottles, etc.) intended to be administered without modification by intravenous infusion using an infusion line and according to the recommended flow rate:
lyophilizates to be resuspended for intravenous infusion, using pharmaceutical solutes known 'to those skilled in the art;
- for maintenance treatments, it is also _ __ possible to envisage the oral route when the chemotherapy treatment favours the oral administration of cytostatic agents. For this purpose, oral lyophilizates (for oral or perlingual absorption) immediate- or delayed-release tablets, oral solutions, suspensions, granules, capsules, etc. may be used.

Interaction (stimulation or inhibition of proliferation) with the generation of clonogenic cells (clonogenic assay) 1 J~ j -The assay used is that described by Hamburger et al., (Science, 1977; 197, 461-463) and Salmon et al., (New England J. Med., 298, 1321-1327). A cell is considered to be clonogenic if it has the capacity to 5 proliferate and to give rise to a cell colony. Human tumour stem cells are the cells behind the neoplastic cells which constitute a given tumour. These tumour stem cells are responsible for the processes of recurrence which can be observed after surgical 10 resection of primary tumours; and are also responsible for the formation of metastases. In a tumour or a tumour cell line, these clonogenic stem cells differ from the other cells of the tumour or of the neoplastic cell line under consideration, by the fact that they conserve their capacity to proliferate in the absence of any solid support.
In this assay, the tumour cells are cultured on a semi-solid support consisting of agar. Only cells which do not require a solid support for their growth (i.e. the very tumorigenic cells termed "anchorage-independent cells" by M.I. Dawson et al., Cancer Res.
1995; 55: 4446-4451; also named clonogenic cells with reference to "clonal growth") are capable of developing on such an agar-based support. Specifically, on such a medium, normal cells - which grow in "adherent mode"
("anchorage-dependence cells" according to the terminology of M.I. Dawson) - such as, for example, fibroblasts, do not survive. Within a tumour cell population, cultured on such a -support, it is these clonogenic cells (associated with an unlimited number of cell divisions, and the proliferation of which is termed "anchorage-independent [clonal] growth" by . M.I. Dawson) which are capable of growing. The percentage of these clonogenic cells within a tumour or a cell line various between 0.1% and O.OOlo. The nonclonogenic cells (associated with a limited number of cell divisions) do not develop in this assay since they require a solid support for their growth which must take place in "adherent mode" ("anchorage-'e . _.

dependent (adherent] growth", according to M.I. Dawson et al., Cancer Res. 1995; 55: 4446-51).
The influence of compounds of formula (I) on the growth of the cell colonies obtained by culturing, for example, the mammary tumour lines MCF7 and MXT, and the colorectal line HT-29, on the semi-liquid culture medium termed "soft agar" was measured. On such a medium, only the clonogenic cells termed "anchorage-independent (clonal) cells" by M.I. Dawson survive and develop. The growth of these cells in such a "nonadherent" mode indicates their degree of tumorigenicity. The inhibition of the growth of the size of a tumour in which a greater number of clonogenic cells have developed then becomes the sign of reinforced cytotoxic activity.
Conversely, this assay can also reveal that a compound is capable of inhibiting the generation/
proliferation of clonogenic cells, which makes the tumour less able to develop, and therefore decreases the population of tumour cells.
The tumour cell lines studied are maintained in culture in 25 cm2 falcon dishes. They are then trypsinized and the cells are well dissociated from each other. The percentage of live cells is determined after trypan blue staining. A cell suspension at the concentration of 5 x 109 to 15 x 109 cells/ml (depending on the cell type under consideration) is prepared in a solution of agar at 0.30. Next, 200 ~1 of this - suspension are seeded int o petri dishes 35 mm in diameter, into which 3 ml of a base layer consisting of a solution of agar at 0.5% are placed. The 200 ~1 of cell suspension are themselves covered with 1.8 mL of an upper layer consisting of a solution of agar at 0.30. The dishes are then placed in an incubator at 37°C, 5o COZ and 70o humidity until treatment. The latter is carried out approximately l to 2 hours after seeding. The compounds to be assayed are prepared at a concentration 100 times greater than the concentration desired, and 50 ~1 of these treating solutions are wi i deposited onto the upper agar layer of the corresponding dishes. In the present study, the final concentration of the products assayed is 10-5, 10-7 and 10-9 M. The dishes are then maintained for 21 days in an incubator. On the 21st day, the dishes are treated by depositing on the upper layer 100 ~l of a solution of MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide). at 1 mg/ml prepared with RPMI 1640 medium, for 3 h at 37°C. After this lapse of time, the cell colonies are fixed by adding 2 ml of formol per dish. After fixing for 24 hours, the formol is evaporated off and the number of cell colonies stained, and therefore consisting of cells which are metabolically active and which have- a surface area greater than 100 ~mz is determined using an inverted microscope.
The mean number of clonogenic cell clones, determined for each experimental condition studied, is expressed as a percentage with respect to the mean number of clonogenic cell clones counted in the control condition and taken to,be equal to 100%. These values, expressed as a percentage with respect to the control condition, are given in Table l, for quercetin.

On the three cell lines MCF7, HT-29 and MXT, quercetin is capable of partially inhibiting the proliferation of the clonogenic cells within the tumour; i.e. of inducing a significant decrease in the number of colonies of these cells with respect to that w obtained in the control condition (from 20o to 50%), and therefore contributes to making the tumours from which they are derived more sensitive to the conventional treatment with cytotoxic agents.
Cytotoxic activity on -the nonclonogenic cells: "MTT assay" . -The influence of the compounds of formula (I) on the nonclonogenic cells was evaluated using the MTT
colorimetric assay.
The principle of the MTT assay is based on the mitochondrial reduction, by metabolically active live cells, of the yellow-coloured product MTT (3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) into a blue-coloured product, formazan. The amount of formazan thus obtained is directly proportional to the amount df live cells present in the culture well(s).
This formazan amount is measured by spectrophotometry.
The cell lines are maintained in monolayer culture at 37°C in closed-cap dishes containing MEM 25 MM HEPES basic medium (Minimum Essential Medium). This medium is suitable for the growth' of a range of varied diploid or primary mammalian cells. This medium is then supplemented with:
- a 5o amount of FCS (foetal calf serum) decomplemented at 56°C for, 1 hour, - with 0.6 mg/ml of L-glutamine, - with 200 IU/ml of penicillin, - with 200 ~g/ml of streptomycin, - with 0.1 mg/ml of gentamicin.

:.. d The 12 human cancer cell lines which were used were obtained from the American Type Culture Collection (ATCC, Rockville, MD, USA).
These 12 cell lines are:
U-373MG (ATCC code: HTB-17) and U-87MG (ATCC
code': HTB-14) which are two glioblastomas, - SW1088 (ATCC code: HTB-12) which is an astrocytoma, - A549 (ATCC code: CCL-185) and A-427 (ATCC
code: HTB-53) which are two non-small-cell lung cancers, - HCT-15 (ATCC code: CCL-225) and LoVo (ATCC
code: CCL-229) which are .two colorectal cancers, - T-47D (ATCC code: HTB-133) and MCF7 (ATCC
code: HTB-22) which are two breast cancers, - J82 (ATCC code: HTB-1) and T24 (ATCC code:
HTB-4) which are two bladder cancers, - PC-3 (ATCC code: CRL-1435) which is a prostate cancer.
In experimental terms: 100 ~l of a cell suspension containing 20 000 to 50 000 (depending on the cell type used) cells/ml of culture medium are seeded into flat-bottomed 96-well multi-well plates and are incubated at 37°C under an atmosphere comprising 50 COz and 70% of humidity. After 24 hours of incubation, the culture medium is replaced with 100 ~,l of fresh medium containing either the various compounds to be tested at concentrations ranging from 10-5 to 10-1° M, or the solvent which was used in order to dissolve the products to be tested (control condition). After 72 hours of incubation under the above conditions, the culture medium is replaced with 100 ~1 of a yellowish solution of MTT dissolved, at a rate of 1 mg/ml, in RPMI 1640. The microplates are re-incubated for 3 hours at 37°C, and then centrifuged for 10 minutes at 400 g:
The yellowish solution of MTT is removed a.nd the blue formazane crystals formed at the cellular level are ,, s dissolved in 100 ~1 of DMSO. The microplates are then shaken for 5 minutes. The intensity of the blue coloration resulting, therefore, from the transformation of the yellow MTT product into blue forrnazane by the cells still alive at the end of the experiment is quantified' by spectrophotometry using a machine of type DYNATECFF IMMUNOASSAY SYSTEM at the wavelengths of 570 nm and 630 nm corresponding, respectively, to the wavelengths of maximum absorbence of the formazane and to the background noise. Software integrated into the spectrophotometer calculates the mean values of optical density, and the standard deviation (Std. Dev.) and standard error of the mean (SEM) values. - -By way of example, the results of the mean optical density, expressed as percentage with respect to the mean optical density measured in the control condition (taken to be equal to 100$), obtained - by way of nonlimiting example - with a flavonoid:

These results show that quercetin has weak antitumour power. This product, which is non-cytotoxic, induces inhibition of the overall cell proliferation of these lines only at the concentration of 10-5 M, and this inhibition doe s not exceed 200: At the other concentrations assayed; only a few minor effects can be detected, 3. Determination of the maximum tolerated dose (MTD):
The evaluation of the maximum tolerated dose was carried out in 4- to 6-week-old B6D2F1/Jico mice.
The compounds were administered via the intraperitoneal route at increasing doses ranging. ~ from - 2.5 to 160 mg/kg. The value of the MTD (expressed in mg/kg) is determined based on the observation of the survival rate of the animals over a period of 14 days after a single administration of the product under consideration. The evolution of the weight of the animals is also monitored during this period. When the value of the MTD is greater than 160 mg/kg, the value of the MTD is assimilated to 160 mg/kg by default.
The quercetin is assocated by default with an MTD equal to 160 mg/kg. This result emphasizes that the products belonging to the flavonoid family have no direct toxicity and can be used at high tissue concentrations, and therefore at high doses.
