3β-치환 5-Androstene-17-Carboxamides 합성과 5α-Reductase 저해 활성 = Synthesis and 5α-Reductase Inhibitory Activity of 3β-Substituted 5-Androstene-17-Carboxamides

다국어 초록 (Multilingual Abstract)

A series of 3β-substituted 5-androstene-17β-carboxamides were synthesized from analogs of 3β-hydroxy-5-androstene-17β-carboxylic acid (1) with tert-butylamine, N,N-diethylamine and 3-aminopyridine and some compounds were epoxidized with mCPBA. A rat prostate testosterone 5α-reductase inhibitory activity of synthesized compounds was assessed by radioimmunoassay using [1,2,6,7-3H]-testosterone as substrate. All synthesized compounds showed lower activity than finasteride and the N-(3-pyridino)-3β-carboxycarbonyloxy-5-androstene-17β-carboxamide (12) showed weak inhibitory activity (IC50: 2.4×10-7 M).
