Abstract
Derivatives of eplandrosterone and progesterone were synthesized. The androgenic and the anabolic activities of some of tlieln were investigated on prepubertal male albino rats of 21 days old by:-i determining tlie weight gain of the body, levator ani muscle, ventral prostate gland, testis, selniilal vesicles, vas deferens and epididymis, ii- estimation of serum luteinizing (LH) hormone, iii- histopatliological examination of the testis and ventral prostate glands. The results from this study showed that the presence of an appended substituted 2- aminopyridine ring at the C- 17 of testosterone gave the maximum androgenic activity, whereas the presence of a substituted piperidine ring fused to ring D of 5 α- androstane exhibited tlie maximum anabolic activity. However, fusion of a pyrazoline moiety with the ring D of 5 α- androstane led to a compound with considerable androgenic and anabolic activity.
