摘要： The present invention relates to steroidal esters of 17-oximino-5-androsten-3-ol, of compound of general formula (A) wherein R is selected from a group consisting of arylalkyl, aryl, substituted aryl. The ester derivatives are synthesized starting from Dehydroandrosterone acetate. The compounds were tested for their antiproliferative activity and 5α-reductase inhibitory activity in comparison to Finasteride. Decreased androgen level have been found in serum of animal treated with newly synthesized compounds. These compounds have also shown better cytotoxicity in comparison to reference drug Finasteride. Thus such compounds can be useful in treatment of androgen dependent disorder of prostate alone or by synergistic effect they can decrease the size of prostate due to their antiproliferative activity.
