A new approach to the synthesis of isomeric 19-hydroxypregn-4-en-20-one (1) and 19-hydroxy-5β-pregn-3-en-20-one (2), the selective ligands of membrane progesterone receptors, in a ratio of 1.5:1 is presented. The effect of these steroids on the gene expression of several cytokines (TNFα, IL-1β, IL-6, and TGFβ) in K562 cells was studied. Progesterone and compound 1 acted unidirectionally, significantly
一种合成异构体 19-hydroxypregn-4-en-20-one (1) 和 19-hydroxy-5β-pregn-3-en-20-one (2)(膜孕酮受体的选择性配体)的新方法,以 1.5:1 的比例呈现。研究了这些类固醇对 K562 细胞中几种细胞因子(TNFα、IL-1β、IL-6 和 TGFβ)基因表达的影响。孕酮和化合物 1 单向作用,显着降低这些细胞中的 TGFβ mRNA 水平。化合物 2 表现出最高的活性,它调节三个研究基因的表达,增加 TNFα mRNA 和 IL-1β mRNA 的水平并降低 TGFβ mRNA 的水平。在 K562 细胞中发现的膜孕酮受体的合成选择性配体的免疫调节作用与天然激素的作用相当(1)甚至超过(2)。
