Abstract
Novel rel-(5R,6S,7S)-2-oxo-5,7-diaryl-3,5,6,7-tetrahydro-2H-thiopyrano[2,3-d]thiazol-6-yl-oxo-acetic acids were synthesized in 52–70% yields via regioselective and diastereoselective hetero-Diels-Alder reaction of 5-arylidene-4-thioxo-2-thiazolidinones with a series of arylidene pyruvic acids. The synthesized compounds were evaluated for anticancer activity in NCI60 cancer cell lines and for antiexudative activity on the carrageenan edema model in rats. Biological screening data led to identification of 3e as having moderate antitumor activity on the colon cancer HT-29 cell line and of 3b as having promising antiexudative effect.
摘要
新型rel-(5R,6S,7S)-2-氧代-5,7-二芳基-3,5,6,7-四氢-2H-噻吩并[2,3-d]噻唑-6-基-氧代-乙酸在52-70%的产率下通过5-芳基亚亚甲基-4-硫代-2-噻唑烷酮与一系列芳基亚亚甲基丙酮酸的区域选择性和对映选择性异-Diels-Alder反应合成。合成的化合物在NCI60癌细胞系中进行了抗癌活性评价,并在大鼠卡拉胶水肿模型上进行了抗渗出活性评价。生物筛选数据表明3e在结肠癌HT-29细胞系中具有中等抗肿瘤活性,3b具有有希望的抗渗出效果。
