摘要:
Compounds of the formula I ##STR1## wherein R.sub.1 hydrogen or methyl; R.sub.2 is methyl; R.sub.3 hydrogen, Alk-R.sub.4, X-Alk, C.sub.1-6 -X-Alk, XCO-Alk, CN, CO-Alk, CO-Ar, CO-O-Alk, CO-NH-Alk, CO-NH-Ar, CO-NH-Het and CO-N(Alk).sub.2 ; Alk is C.sub.1-12 straight or branched alkyl; Ar is phenyl, Het is piperidinyl, piperizinyl, pyrrolidinyl, pyrrolyl, furanyl or thienyl and X is O, N or S. Such compounds are useful in the treatment of pathologic conditions that benefit from blockade of isozymes of 5.alpha.-reductase.
摘要:
17.beta.-acyl-3-carboxy-androsta-3,5-dienes as testosterone 5.alpha.-reductase inhibitors of the formula: ##STR1## wherein R is C.sub.3 -C.sub.8 cycloalkyl, which can be substituted with C.sub.1 -C.sub.4 alkoxy or C.sub.6 -C.sub.12 aryl, which can be substituted with one or more of: --OH, --OC.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkyl, --(CH.sub.2).sub.m OH, --(CH.sub.2).sub.n COOH, including protected --OH, where m is 1-4, n is 1-3, and pharmaceutically acceptable salts or esters thereof. Also described is a pharmaceutical formulation. The above compounds are active as testosterone 5.alpha.-reductase inhibitors and thus are useful topically for treatment of acne, seborrhea, female hirsutism, and systemically in treatment of benign prostatic hypertrophy.
摘要:
New intermediates in the synthesis of 17.beta.-acyl-3-carboxy-androsta-3,5-dienes, of the formula: ##STR1## wherein R.sup.2 is 2-thiopyridyl, andR.sup.3 is C.sub.2 -C.sub.4 alkoxycarbonyl, C.sub.1 -C.sub.4, or trifluoromethylsulfonyloxy. The above compounds are useful intermediates in producing testosterone 5.alpha.-reductase inhibitors which are useful topically for treatment of acne, seborrhea, female hirsutism, and systemically in treatment of benign prostatic hypertrophy.
摘要:
This invention is concerned with 6-(substituted amidino-9-substituted benzyl purine derivatives and in particular 6-(aminomethylideneamino)-9-substituted benzyl purines. The compounds are active anticoccidial agents and suitable compositions and methods are described for the administration of such compounds to poultry for the prevention and treatment of coccidiosis.
摘要:
This invention is concerned with a novel process for the preparation of N.sup.6 -alkyl-arprinocid (6-alkyl-amino-9-substituted benzyl purines). Such compounds are active anticoccidial agents. The process involves the preparation of a Schiff base from an acetal of dialkylformamide and reduction with a metal hydride.
