Definitions
- the present invention relates to the use of compounds of the general formula I for increasing libido in post-menopausal women.
- the present invention also embraces pharmaceutical compositions comprising these compounds and methods of using the compounds and their pharmaceutical compositions.
- Centchroman is a non-steroidal compound known to have antiestrogenic activity. It is in use in India as an oral contraceptive (see, for example, Salman et al., U.S. Patent Specification No. 4,447,622; Singh et al., Acta Endocrinal (Copenh) 1 26 ( 1 992), 444 - 450; Grubb. Curr Opin Obstet Gynecol 3 (1 991 ), 491 - 495; Sankaran et al., Contraception 9 ( 1 974), 279 - 289; Indian Patent Specification No. 1 291 87).
- Centchroman has also been investigated as an anti-cancer agent for treatment of advanced breast cancer (Misra et al., Int J Cancer 43 (1 989), 781 - 783. Recently, centchroman as a racemate has been found as a potent cholesterol lowering pharmaceutical expressed by a significant decrease of the serum concentrations (S.D. Bain et al., _ Min Ben Qss. 3 (1 994), S 394).
- U.S. patent 5,453,442 describes methods of lowering serum cholesterol and inhibiting smoother muscle cell proliferation in humans and inhibiting uterine fibroid disease and endometriosis in women by administering compounds of formula I as shown therein.
- US patent 5,280,040 describes methods and phar- maceutical compositions for reducing bone loss using 3,4-diaryl chromans and their pharmaceutically acceptable salts. There is no disclosure in the patents of using the compounds to increase libido in post-menopausal women. There remains a need in the art for compositions and methods useful for increasing libido in post-menopausal women.
- This invention provides the use of a compound having the formula
- R ⁇ R 4 and R 5 are individually hydrogen, hydroxy, halogen, tri- fluoromethyl, C,. 6 alkyl, C ⁇ alkoxy or (tertiary aminoXC, ⁇ alkoxy); and R 2 and R 3 are individually hydrogen or C . e alkyl, or a pharmaceutically acceptable salt thereof, for the manufacture of a pharmaceutical composition for increasing li- bido in post-menopausal women.
- the current invention concerns the discovery that the compounds of formula I are useful for increasing libido.
- the methods of treatment provided by this invention are practiced by administering to a human in need a dose of a compound of formula I or a pharmaceutically acceptable salt thereof, that is effective to increase libido.
- post-menopausal women is defined to include not only women of advanced age who have passed through menopause, but also women who have been oophorectomised, hysterectomized or oophorohysterectomised or for some other reason have suppressed estrogen production, such as those who have un- dergone long-term administration of corticosteroids, suffer from Cushions' syndromes or have gonadal dysgenesis.
- libido refers to those aspects of the human psy- che which are related to sexual interest and drive. Additionally, the expression “libido” refers to related psychic attitudes concerned with mental well-being and which refer to such characteristics as mental alertness and activity, creativity, enthusiasm, sociability and an awareness of interpersonal relationships. Libido is generally recognized to be the result of a complex interaction of factors in which genetic, anatomic, neurologic, psychologic and biochemical factors all play prominent roles. The exact mechanism by which the compounds of the present invention achieve this effect is not understood except to the extent that it is attributable to a biochemical mechanism.
- R , R ⁇ and R° are individually hydrogen, hydroxy, halogen, trifluoromethyl, C,. 6 alkyl, C,. 6 alkoxy or (tertiary ammoMC ⁇ alkoxy); and R ⁇ and
- R ⁇ are individually hydrogen or a C, ⁇ alkyl.
- C, ⁇ alkyl includes straight and branched chain alkyl radicals containing from 1 to 6 carbon atoms, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, tert-butyl, n-amyl, sec- amyl, n-hexyl, 2-ethylbutyl, 2,3-dimethylbutyl and the like.
- 6 alkoxy includes straight and branched chain alkoxy radicals containing from 1 to 6 carbon atoms, such as methoxy, ethoxy, n-propoxy, isopropoxy, n-butoxy, tert- butoxy, n-amyloxy, sec-amyloxy, n-hexyloxy, 2-ethylbutoxy, 2,3-dimethylbutoxy and the like.
- Hydrogen includes chloro, fluoro, bromo and iodo.
- (tertiary amino)(C 1 . 6 alkoxy) is a C 1-6 alkoxy group which is substituted by a tertiary amino radical.
- the tertiary amino radical may be a N,N-dialkylamine such as a N,N-dimethylamino, N,N-diethylamino, N,N-dipropylamino and N,N- dibutylamino or a polymethyleneimine, e.g., piperidine, pyrrolidine, N- methylpiperazine or morpholine.
- Preferred compounds include those in which R 1 is C 1-6 alkoxy; R 2 and R 3 are C ⁇ alkyl, especially methyl; R 4 is hydrogen; and R 5 is (tertiary aminoMC ⁇ e alkoxy) of the polymethyleneimine type.
- R ' is in the 7-position and is C,.
- each of R 2 and R 3 is methyl, R ⁇ is hydrogen, and R ⁇ is in the 4- position and is a (tertiary aminoMC ⁇ e alkoxy) radical such as 2-(pyrrolidin-1 - yl)ethoxy with formula II
- the compounds of formula I in the transconfiguration. These compounds may be used as racemic mixtures, or the isolated d- or I- enantiomers may be used. The trans-l-enantiomers are more preferred.
- a particularly preferred compound for use within the present invention is cen- tchroman having the formula IV
- 3,4-diarylchromans of formula I may be prepared in the form of pharmaceutically acceptable salts, especially acid-addition salts, including salts of organic acids and mineral acids.
- salts include salts of organic acids such as formic acid, fumaric acid, maleic acid, acetic acid, propionic acid, glycolic acid, lactic acid, pyruvic acid, oxalic acid, succinic acid, malic acid, tartaric acid, citric acid, benzoic acid, salicylic acid and the like.
- Suitable inorganic acid-addition salts include salts of hydrochloric, hydrobromic, sulphuric and phosphoric acids and the like.
