A NON-HORMONAL APPROACH TO MALE CONTRACEPTION

摘要

The present invention provides a method by which to reversibly render male mammals infertile. Thus, the disclosed N-substituted imino compounds, and pharmaceutical compositions thereof, completely impair the fertility of male mammals, but exhibit no effect on that of female mammals, and are thus usefu l as male contraceptives. Particularly efficacious compounds are imino sugars derived from N-alkylated piperidines of the formulae: wherein R2 is can be a linear or branched C1-18 alkyl, C2-18 alkenyl or alkynyl; or aralkyl; which may be optionally substituted with one or more of -OH; -F; -CI; -Br; -I; -NH 2; alkyl- and dialkylamino; linear or branched C1-6 alkyl, C2-6 alkenyl and alkynyl; aralkyl; linear or branched C1-6 alkoxy, aryloxy; aralkoxy; -CN, - NO2, -COOH, -COO(alkyl); -COO(aryl); - C(O)NH(C1-6 alkyl); -C(O)NH(aryl); sulfonyl; (C1-6 alkyl)sulfonyl; arylsulfonyl; sulfamoyl, (C1-6 alkyl)sulfamoyl; (C1-6 alkyl)thio; (C1-6 alkyl)sulfonamide; arylsulfonamide; - NHNH2; and -NHOH.
