important class of heterocyclic compounds with diverse biological activities. Here, we report a series of pteridin-7(8H)-one derivatives and their antiproliferative activities toward MKN-45, MGC-803, EC-109, and H1650. Structure-activity relationship studies showed that compound 12 exerted the most potent antiproliferative activity against MKN-45 and MGC-803 with the IC50 values of 4.32 and 7.01 μM
蝶啶是重要的一类具有多种生物活性的杂环化合物。在这里,我们报告一系列的蝶呤7(8 H)一衍生物及其对MKN-45,MGC-803,EC-109和H1650的抗增殖活性。结构-活性关系研究表明,化合物12对MKN-45和MGC-803表现出最强的抗增殖活性,IC 50值分别为4.32和7.01μM。此外,化合物12诱导MKN-45细胞的形态变化和凋亡,Bax表达增加,Bcl-2表达下调并引起caspase-3 / 9裂解。此外,我们首先报道了新型双环8,9-dihydro-7 H的构建-嘌呤-8-羧酸盐支架通过具有两个CN键和已建立的手性碳中心的竞争性5-内基环化反应进行构建。
