    摘要: Novel amino substituted 4-azasteroid 5.alpha.-reductase inhibitors of formula (I). ##STR1## wherein A is (a), (b) or (c), are claimed as well as pharmaceutically acceptable salts and formulations thereof. These compounds are effective in inhibiting testosterone 5.alpha.-reductase(s) and are thus useful in the treatment of a number of hyperandrogenic conditions including benign prostatic hypertrophy, acne, seborrhea, female hirsutism, and male and female pattern baldness (alopecia).

    摘要: 9-(1,3-Dihydroxy-2-propoxymethyl)guanine and 9-(2,3-dihydroxy-1-propoxymethyl)guanine have been found to have potent anti-viral activity against herpes viruses. These compounds, their acyl derivatives, their phosphate derivatives and their pharmaceutically acceptable salts, pharmaceutical formulations containing these compounds, the treatment of DNA viral or herpes viral infections with these compounds, method of preparing these compounds, and novel intermediates useful in their preparation are all disclosed.The compounds may be prepared by reaction of the appropriate acetoxymethyl ether with diacetylguanine, followed by deprotection. The acetoxymethyl ethers may be obtained by reaction of glycerol formal with acetic anhydride in the presence of a catalyst.
