Synthetic analogues of natural 5Z,9Z-dienoic acids - hybrid molecules based on the oximes of cholesterol, pregnenolone, and androsterone with 1,14-tetradeca-5Z,9Z-dienedicarboxylic acid - were synthesized for the first time and studied for antitumor activity in vitro. The acid was prepared using catalytic cyclomagnesiation of O-containing 1,2-dienes with Grignard reagent in the presence of Cp2TiCl2
首次合成了天然5Z,9Z-二烯酸的合成类似物-基于
胆固醇,
孕烯醇酮和雄甾酮
肟与1,14-十四碳-5Z,9Z-二烯二
羧酸的杂合分子-并在其中研究了其抗肿瘤活性体外。在Cp2TiCl2存在的情况下,使用
格氏试剂,通过含O的1,2-二烯的催化环化反应制备酸,这是关键步骤。使用流式细胞仪,首次证明了新分子在HeLa,Hek293,U937,Jurkat和K562中是有效的细胞凋亡诱导剂。
