tritiated water assay for aromatase, with human placental microsomes as the enzyme source and [1-3H]-androst-4-ene-3,17-dione (83% 3H 1 beta) as the substrate. All of the compounds caused less than 20% inhibition of enzyme activity when tested at one and five times the substrate concentration (0.25 microM, 1.25 microM) and were poorer inhibitors than two known inhibitors, 7 alpha-[(p-aminophenyl)thio]
合成了19-氮杂雄烯二酮(10β-氨基-4-雌烯-3,17-二酮,2)和19-氨基-4-雄烯-3,17-二酮(3)的衍生物作为芳香化酶的潜在抑制剂(雌激素合成酶) )。通过Curtius重排,由3,17-二氧代-4-androsten-19-oic酸(5)合成化合物2及其衍生物。由中间体3,17-双(亚乙基二氧基)-5-androsten-19-al肟(14)合成3的衍生物,该中间体用阮内镍还原为相应的胺(16)。但是,尝试通过几种不同的方法从16种化合物中合成3种母体化合物是不成功的。在human水测试中检测芳香化酶的抑制活性,以人胎盘微粒体为酶源,以[1-3H] -androst-4-ene-3,17-dione(83%3H 1 beta)为酶源。基板。
