TROGLITAZONE COMPOUNDS FOR TREATING CLIMACTERIC

Abstract: The present invention is directed toward the use of the drug Troglitazone and related thiazolidinedione compounds in the treatment of the climacteric and cancer. This use is based on the novel discovery that Troglitazone inhibits steroidogenesis in granulosa cell cultures. This activity is believed to result from the ability of thiazolidinedione derivatives to act as a ligand for the orphan steroid receptor peroxisome proliferator-activated receptor gamma (PPAR gamma ). Troglitazone and related compounds can therefore be used to prevent excessive uterine bleeding during. Further, enhanced translocation of this orphan nuclear receptor into the nucleus of cells will block transcription in rapidly proliferating cancer cells that express PPAR gamma , resulting in loss of cell viability.

Description: DESCRIPTION TROGLITAZONE COMPOUNDS FOR TREATING CLIMACTERIC BACKGROUND OF THE INVENTION The Federal government has rights in the present invention insofar as it was supported by NIH grant No. 1-R01-HD28393. 1. Field of the Invention The present invention relates generally to a novel use of Troglitazone and related thiazolidinedione derivatives. More specifically, it relates to the use of Troglitazone and related thiazolidinedione derivatives in the treatment of the climacteric. It also relates to the use of Troglitazone and the like for the treatment of cancer. 2. Description of Related Art Troglitazone is a member of a class of antidiabetic drugs termed thiazolidinediones. Although the mechanism is unknown, this class of drugs lowers insulin resistance and improves glucose tolerance(Nolan et al, 1994). For these reasons Troglitazone has found use in the treatment of noninsulin-dependent diabetes mellitus (NIDDM) (U.S. Patent No. 5,478,852 incoφorated by reference herein). NIDDM, otherwise referred to as Type II diabetes, is the form of diabetes mellitus which occurs predominately in adults in whom adequate production of insulin is available for use, yet a defect exists in insulin-mediated utilization and metabolism of glucose in peripheral tissues. The population with impaired glucose tolerance progresses to NIDDM at a rate of 5% to 10% of cases per year. Failure to treat NIDDM can result in mortality due to cardiovascular disease and other diabetic complications including retinopathy, nephropathy, and peripheral neuropathy. Administration of Troglitazone can provide effective treatment of populations experiencing impaired glucose tolerance and may result in the delay or prevention of the onset of NIDDM. Moreover, Troglitazone has been further implicated in the treatment of polycystic ovary syndrome (PCO). This is a syndrome in women that is characterized by chronic anovulation and hypεrandrogenism. Women with this syndrome often have insulin resistance and an increased risk for the development of noninsulin-dependent diabetes mellitus. In women with PCO given Troglitazone (400 mg every day), insulin resistance was reduced and 2 of the 25 women studied had ovulatory menses (Dunaif et al, 1996). While advances continue to be made in chemotherapy treatment of cancer, effective agents are still lacking for the treatment many types of cancer. One such type is mesenchymal tumors. The mesenchyma consists of the meshwork of embryogenic connective tissue in the mesoderm from which are formed the connective tissues of the body as well as blood vessels and lymphatic vessels. There are many types of mesenchymal tumors including but not limited to sarcomas (general), rhabdomyosarcomas, fibrosarcomas, retinoblastoma, hemangiopericytoma, congenital mesoblastic nephroma, and mesotheliomas (Pierce and Figlin, 1992; Odell, 1996; Connelly and Budd, 1996). These types of tumors are aggressive and fast growing, thus development of effective chemotherapeutic agents for their treatment is of particular need. One mechanism through which thiazolidinediones are believed to have biological effect is their ability to serve as a high affinity ligand for the orphan steroid receptor peroxisome proliferator-activated receptor gamma (PPARγ) (Lehmann et al, 1995). PPARγ is a member of the nuclear receptor superfamily of orphan steroid receptors that serve as transcription factors (Motojima, 1993). This family includes receptors for the steroid, thyroid and retinoid hormones. Activation of PPARγ is implicated in adipocyte differentiation through the activation of adipocyte-specific gene expression (Lehmann et al, 1995). This gene expression is mediated through binding to a PPARγ response element (PPRE) in the promoter region of target genes (Forman et al, 1995). This PPRE is composed of a directly repeating core site separated by one nucleotide (NNN-AGGTCA-N-AGGTCA). To bind to a PPRE, PPARγ must form a heterodimer with the 9-cis retinoic acid receptor (RXR). This sequence is classified as a DR-1 consensus sequence that is universal for orphan receptors (Vidal-Puig, 1996). Because of the universal nature of this consensus sequence, other transcription factors can bind to the PPRE and compete with the binding of PPARγ. One such transcription factor is COUP-TFII that antagonizes PPAR signaling in mammalian cells (Marcus et al, 1996). PPARγ is in a family of three orphan receptors that are encoded by different genes (Motojima, 1993). The three PPAR genes are PPARα, PPARδ, and PPARγ (Motojima, 1993). Moreover, 2 isoforms of PPARγ also exist, PPARγ 1 and γ2 (Vidal-Puig et al, 1996). These 2 proteins differ only in their NH 2 -terminal-30 amino acids and are the result of alternative promoter usage and differential mRNA splicing (Vidal-Puig et al, 1996). In addition to thiazolidinediones, another ligand for the PPARγ nuclear receptor is the arachidonic acid metabolite 15-deoxy-delta 12 ' 14 -prostaglandin J 2 (15d-PGJ 2 ). This prostaglandin activates PPARγ-dependent adipogenesis, but activated PPARα only at high concentrations (Forman et al, 1995; Kliewer et al, 1995). This is further evidence that the PPAR family subtypes are distinct from one another in their pharmacological response to ligands. The climacteric is defined as the syndrome of endocrine, somatic and psychological changes occurring at the termination of the reproductive period in the female. The menstrual irregularities are episodes of prolonged menstrual bleeding caused by a loss of ovulation. The loss of ovulation is caused by a failure of development of ovarian follicles. Currently the most common method for treatment of the climacteric is hormone replacement, including administration of birth control pills, oral administration of estrogen and progesterone preparations or oral administration of progesterone only preparations (Shaaban, 1996). While relieving symptoms of the climacteric, these treatments have many associated risks and side effects. Risks associated with hormone treatment include endometrial carcinoma, hypertension, hyperlipidemia, cholelithiasis (gallstones), breast cancer, and deep venous thrombosis (Barentsen, 1996). Compounds useful for practicing the present invention, and methods of making these compounds are known.

SUMMARY OF THE INVENTION The present invention is the result of the suφrising finding that Troglitazone and related thiazolidinedione compounds inhibit steroidogenesis in granulosa cells. A related aspect of the present invention is the discovery that therapeutic levels of Troglitazone can kill rapidly growing cancerous cells expressing the oφhan nuclear receptor PPARγ, while not affecting the viability of normal cells. The discovery of these new uses for Troglitazone and related compounds provides important new agents for the treatment of certain types of cancers and for the treatment of the climacteric. The term climacteric is well known in the art as the syndrome of endocrine, somatic and psychological changes occurring at the termination of the reproductive period in the female. A type of cancer which is particularly likely to be treatable with troglitazone and related thiazolidinedione derivatives are mesenchymal tumors. The mesenchyma consists of the meshwork of embryogenic connective tissue in the mesoderm from which are formed the connective tissues of the body as well as blood vessels and lymphatic vessels. There are many types of mesenchymal tumors including but not limited to sarcomas (general), rhabdomyosarcomas, fibrosarcomas, retinoblastoma, hemangiopericytoma, congenital mesoblastic nephroma, and mesotheliomas. Studies show that Troglitazone is a ligand for the oφhan nuclear receptor PPARγ. Translocation of this transcription factor in the nucleus of cells at sufficient rates inhibits transcription and reduces progesterone production in normal granulosa cells without a loss in cell viability. However, this inhibition of transcription in rapidly dividing cancer cells expressing PPARγ results in the loss of cell viability and inhibition of cell growth. The mechanism of PPARγ inhibition of gene transcription most likely results from the competition of the PPARγ transcription factor with the other oφhan nuclear factors binding to DR-1 consensus elements on genes and impairing the promoter activity of those elements. The inhibitory effects of Troglitazone on steroidogenesis make it useful for the reduction of menstrual bleeding in women as they develop reduced ovulation as they approach menopause. Because there is no loss of viability in normal cells, but a reduction in rapidly growing cancer cells, Troglitazone and related compounds may also be used in the treatment of cancer, to impair the growth of cancer cells without killing normal cells As agents having the aforementioned effects, the compounds of the following formulas are useful in treating individuals.

A solid carrier can be one or more substances which may also act as diluents, flavoring agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material. In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active component. In tablets, the active component is mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the size and shape desired. The powders and tablets preferably contain from five or ten to about seventy percent of the active compound. Suitable carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter and the like. The term "preparation" is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration. For preparing suppositories, a low melting wax, such as a mixture of fatty acid glycerides or cocoa butter, is first melted and the active compound is dispersed homogeneously therein, as by stirring. The molten homogenous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify.

EXAMPLE 1 Suppression of Progesterone Production in Porcine Granulosa Cells with Troglitazone and Related Compounds Initial studies investigated the dose-response of Troglitazone and related compounds on progesterone production in cultures of porcine granulosa cells. Porcine granulosa cells were isolated from 1- to 5-mm follicles of ovaries from immature swine (60-70 kg) obtained from a local slaughterhouse (Urban et al, 1994). The cells were plated in Eagle's minimum essential medium and 3% fetal calf serum (FCS) at a concentration of 20-30 million cells/60-mm dish for 12-16 h to facilitate granulosa cell attachment to the plates. Monolayer cultures were maintained at 37°C in 5% CO 2 throughout the study. After granulosa cell attachment, medium containing the FCS was discarded and serum-free medium with varying concentrations of Troglitazone, pioglitazone and BRL 49653 was added for 24 h. One ml of medium was collected for measurement of progesterone by an assay previously described that uses the chromatographic separation of steroids to enhance specificity (Urban et al, 1994). As shown in FIG. 1, all three of the drugs suppressed progesterone production by porcine granulosa cells in a dose-dependent fashion, but Troglitazone was more potent at suppressing progesterone production than 2 other drugs in the thiazolidinedione class of drugs (FIG. 1). This demonstrated the likely utility of Troglitazone and related thiazolidinedione derivatives in the treatment of the climacteric, and that thiazolidine derivatives have physiologic activities similar to those of Troglitazone. The time course for the suppression of progesterone was done in the same porcine granulosa cell culture system. Cells were treated for up to 24 h with zero, 1 , or 10 μg/ml of Troglitazone. As shown in FIG. 2, progesterone production was suppressed by Troglitazone as early as 4 h. The concentration of Troglitazone did not affect the time of onset of suppression (FIG. 2). EXAMPLE 2 Cell Viability of Porcine Granulosa Cells During Treatment With Troglitazone Although there was not a significant decrease in DNA content between control and Troglitazone-treated porcine granulosa cells, total protein concentrations were lower in the Troglitazone treatment groups. Therefore, cell viability was tested in these cells using a colorimetric assay that is dependent on the oxidation of MTS to formazan (absorbance measured at 490 nm) by dehydrogenase enzymes found in metabolically active cells (Promega, Madison Wl). This assay was verified in porcine granulosa cells by showing a linear increase in absoφtion with increasing cell density. Even at the highest doses of Troglitazone (100 μg/ml), there was not a decrease in cell viability in granulosa cells (FIG. 3). This demonstrates that Troglitazone and related thiazolidinedione derivatives are unlikely to affect the viability of normal granulosa cells. EXAMPLE 3 Studies on the Mechanism of Troglitazone Suppression of Porcine Granulosa Cell Progesterone Production The suppression of progesterone production in porcine granulosa cells by Troglitazone could be due to effects of the drug on the supply of cholesterol to the mitochondria. Before investigating proteins in the pathway of cholesterol transport to the mitochondria, it was first tested whether Troglitazone would inhibit progesterone production when cells were co-treated with 25-OH cholesterol. This compound diffuses directly to the P-450 cholesterol side-chain cleavage enzyme (P450scc) in the mitochondria and acts as a substrate for progesterone production (Veldhuis and Furlanetto, 1985). Treatment of porcine granulosa cells with Troglitazone and 25-OH cholesterol demonstrated that even in the presence of 25-OH cholesterol, Troglitazone suppressed progesterone production (FIG. 4). Having shown that Troglitazone did not impair the cholesterol transport system in porcine granulosa cells, the effects of the drug on the mRNA concentrations of the rate-limiting enzyme in the steroidogenic pathway, P450scc, were determined (Miller, 1988). Suppression of transcription of this enzyme would result in decreased progesterone production by granulosa cells. Porcine granulosa cells were cultured and treated with Troglitazone (5 μg/ml) for 24 h. Troglitazone treatment did not suppress mRNA concentrations of P450scc (FIG. 5) suggesting that the compound does not inhibit progesterone synthesis by decreasing expression of this specific enzyme. With no evidence of a direct effect of Troglitazone on the transport of cholesterol or the mRNA concentrations of the rate-limiting enzyme for steroidogenesis, P450scc, a more general effect of Troglitazone on cellular function was studied. As stated above, Troglitazone is a ligand for the PPARγ oφhan nuclear receptor (Lehmann, 1995). This receptor binds to a DR-1 consensus element that is non-specific and will bind many transcription factors in this nuclear receptor family. It was indicated that a marked translocation of PPARγ into the nucleus could disrupt the function of many genes. This mechanism would make rapidly growing cells expressing PPARγ, such as those of many types mesenchymal tumors, more susceptible to this phenomenon. A DR-1 consensus oligonucleotide was synthesized (NNN-AGGTCA-N- AGGTCA, SEQ ID NO:l) and used in electrophoretic mobility gel shift assay (EMSA) with 15 μg of nuclear extract protein from porcine granulosa cells treated with Troglitazone, pioglitazone and BRL 49653. All three of the compounds, Troglitazone, pioglitazone and BRL 49653 increased binding to the PPRE in granulosa cell nuclear extracts (FIG. 6), indicating that all three compounds had a similar effect with respect to binding of the DR-1 consensus sequence, although the binding was greatest with Troglitazone. Binding was specific in that unlabeled PPRE competitively inhibited binding of the labeled DNA (FIG. 6). Moreover, an antibody to PPARγ showed a supershifted band in EMSA (FIG. 6). To further correlate the enhanced binding of PPARγ to the DR-1 consensus sequence after treatment with Troglitazone, cultures of porcine granulosa cells were treated with Troglitazone, pioglitazone, and BRL 49653 (all at a 5 μg/ml concentration) and nuclear extract protein was collected. As shown in FIG. 7, suppression of progesterone in these cells occurred with Troglitazone and this correlated with the increased binding to the DR-1 consensus sequence in EMSA. EXAMPLE 4 Dose-Response of Human HGL5 Cells Treated with Troglitazone A PPARγ expressing human granulosa cell line (HGL5) was selected that had been transformed by the E6 and E7 regions of the human papillomavirus (Rainey et al, 1994). Although these cells were slow growing in cell culture, they retained their steroidogenic capacity (Rainey et al, 1994). Troglitazone also suppressed progesterone production in this cell line, although the suppression occurred only at concentrations of Troglitazone greater than 10 μg/ml (FIG. 8). Moreover, there was a biphasic response to Troglitazone, with lower concentrations actually increasing progesterone production (FIG. 8). EMSA was next performed on nuclear extract protein from HGL5 cells to determine whether the increase in binding to the DR-1 consensus sequence induced by Troglitazone in porcine granulosa cells was also present in this cell line. Troglitazone at a 30 μg/ml concentration inhibited progesterone production by these cells and also markedly increased binding to the PPRE (FIG. 10). The effects of Troglitazone on cell viability in the HGL5 cells was next tested. A similar assay was used as described above for porcine granulosa cells, using MTT instead of MTS for conversion to formazan. As shown in FIG. 9, Troglitazone concentrations as low as 0.5 μg/ml caused a loss of cell viability. This demonstrated the utility of Troglitazone in decreasing the viability of this immortal, transformed cell line. EXAMPLE 5 Treatment of Mouse Fibroblast NWTb3 Cells with Troglitazone: Effects on Cell Viability, and Binding to the PPRE Because a decrease in cell viability was observed with the human granulosa cell line (HGL5), the effects of Troglitazone on 2 other cell lines was studied. The first cell line tested with Troglitazone was a PPARγ expressing transformed mouse fibroblast line derived from NIH 3T3 cells which over expresses the IGF-I receptor (NWTb3). These cells are of mesenchymal origin and grow more rapidly than the HGL5 line. In this cell line Troglitazone caused a loss of cell viability at concentrations of 1.0 μg/ml and greater (FIG. 1 1). These results indicated that Troglitazone is effective in decreasing the viability of PPARγ-expressing transformed cell lines, and further indicate the applicability of Troglitazone in the treatment of tumor cells. EMSA was also done on nuclear extract protein from NWTb3 cells treated with 10 μg/ml of Troglitazone to determine whether an increase in binding to the PPRE was seen as in the 2 previous systems (porcine and human granulosa). As shown in FIG. 12, an increase in binding of PPRE was seen during treatment with Troglitazone. This again, suggests that the effects of troglitazone and related thiazolidinedione derivatives are mediated by binding to the DR-1 consensus sequence. EXAMPLE 6 Effects of Troglitazone on the Viability of Human MCF-7 Cells A non-PPARγ expressing human breast cancer cell line, MCF-7, was tested. In this cell line, which is non-mesenchymal in origin, cell viability decreased only with high concentrations of Troglitazone (FIG. 13). Nuclear extract protein collected from MCF-7 cells treated with 30 μg/ml of Troglitazone for 24 h and used in EMSA with the DR-1 consensus sequence showed no presence of binding. The results show that loss of cell viability is correlated with the expression of PPARγ in transformed and cancer cells. EXAMPLE 7 Treatment of the Climacteric with Troglitazone A female human patient typically enters the climacteric from about age 40 to age 55, resulting in irregular menses and episodes of prolonged bleeding. In the case of a patient with a history of deep venous thrombosis, severe hypertension, severe hyperlipidemia, breast cancer, endometrial cancer, or cholelithiasis, Troglitazone would be the primary treatment option. In the absence of these risk factors, Troglitazone may be offered as an option to hormone treatment. Prevention of irregular menstrual bleeding may be achieved in a human climacteric patient by administration of a therapeutically active amount of Troglitazone. During an initial treatment period, administration of Troglitazone in an amount of about 200 mg per day may be directed with monitoring of condition. If symptoms continue, administration may be increased to about 400 mg per day. Estrogen levels in the patient can be periodically monitored for low estrogen levels or symptoms of low estrogen levels, such as hot flashes. Treatment with Troglitazone may continue until these symptoms develop or there is evidence that the patient is menopausal. Such evidence may be suggested by an elevation in levels of follicle stimulating hormone. EXAMPLE 8 Treatment of a Human Cancer Patient with Troglitazone Troglitazone may be used for the treatment of tumor cells expressing PPARγ. The studies documented herein, demonstrate that Troglitazone can be used to reduce the viability of PPARγ-expressing cell lines, and that rapidly growing cells are particularly sensitive to Troglitazone. Thus tumors that are known to express PPARγ would be tumor types likely to be treated with troglitazone. Mesenchymal tumors are one type of tumor which is particularly likely to express PPARγ. In cases where it is not known if a tumor expresses PPARγ, one may use a number of methods to screen tumor cells for expression of PPARγ including EMSA, as well as Northern and Western Blot analysis. Tumor cell lines may be also be screened for sensitivity to Troglitazone in vitro or in vivo. Cultured tumor cells may be treated with concentrations of Troglitazone varying from about 0.1 μg to about 30 μg. Viability of the tumors cells may then be assayed using a colorimetric assay that is dependent on the oxidation of MTS to formazan (absorbance measured at 490 nm) by dehydrogenase enzymes found in metabolically active cells (Promega, Madison Wl). In vivo treatment of a human cancer patient with Troglitazone may be achieved by administration of about 400 mg per day of Troglitazone. An initial period of treatment with Troglitazone or a thiazolidinedione derivative of a cancer patient may be initiated with monitoring of condition. Treatment may be continued or discontinued based on condition of the patient. Use of Troglitazone therapy in conjunction with other chemotherapeutic agents, radiation, or surgery may in many cases be the preferred mode of treatment. Troglitazone treatment therefore, would inhibit the growth of the cancer so that other therapies may be added, thereby increasing the likelihood of curing the patient. Troglitazone and related thiazolidinedione derivatives may additionally be used to treat patients with severely metastatic disease. Such treatment may slow tumor growth and reduce tumor mass, thereby prolonging survival and increasing the quality of life of terminal cancer patients.
