Two series of acetylenic derivatives of cholesterol were synthesized from stigmasterol and pregnenolone. These compounds carry an acetylenic function at C-22 and were devised with the aim to inhibit the C-22 hydroxylation of ecdysone biosynthesis by a suicide-substrate mechanism. Two of these compounds (15a, 15f) inhibit the synthesis of ecdysone in follicular cells under in vitro conditions. The inhibition
从豆甾醇和孕烯醇酮合成了胆固醇的两个炔属衍生物。这些化合物在C-22处具有乙炔功能,旨在通过自杀底物机制抑制蜕皮激素生物合成的C-22羟基化。这些化合物中的两种(15a,15f)在体外条件下可抑制卵泡细胞中蜕皮激素的合成。该抑制是对C-22羟化酶系统的选择性。
