Anabolic and androgenic activities, in rat, of some nandrolone and androstanolone esters

Anabolic and androgenic activities, in rat, of some nandrolone and androstanolone esters. Chaudry, M. A. Q.; James, K.In this study， 52230-63-4 and 35800-55-6 are also used. C.; Ng, C. T.; Nicholls, P. J. (Welsh Sch. Pharm., Univ. Wales, Cardiff, Wales). J. Pharm. Pharmacol., 28(12), 882-5 (English) 1976. CODEN: JPPMAB. DOCUMENT TYPE: Journal CA Section: 2 (Hormone Pharmacology) The ratio of anabolic activity (assessed as cumulative wt. of rat levator anus muscle responding to a 2.mu.M dose) to androgenic activity (assessed as sum of the cumulative wts. of rat prostate and seminal vesicles responding to a 2.mu.M dose) of nandrolone and androstanolone esters after i.m. injection was detd. Nandrolone propionate [7207-92-3], nandrolone butyrate [18069-72-2], androstanolone propionate [855-22-1], and androstanolone butyrate [18069-66-4] showed min. values of the ratio. The anabolic-androgenic ratios of the nandrolone esters increased from the min. value as the series was ascended. This method appears to give a reliable assessment of anabolic and androgenic activities of steroid esters. .
