Three series of 4-morpholinothieno[3,2-d]pyrimidine derivatives containing arylmethylene hydrazine moiety (11a–f, 13a–k and 15a–h) were synthesized and their chemical structures as well as the relative stereochemistry were confirmed. The synthesized compounds were evaluated for their cytotoxicity against three cancer cell lines (H460, HT-29, MDA-MB-231). Most of them exhibited moderate to significant cytotoxicity and high-selectivity against one or more cell lines, especially compounds 11c, 13b, 15f and 15g possessing dramatically increased cytotoxicity as compared with the positive controls, which were further evaluated for six other cancer cell lines and one normal cell line. The most promising compound 11c, bearing 3,4-methylenedioxy phenyl group, showed remarkable cytotoxicity against H460, HT-29 and MDA-MB-231 cell lines with IC50 values of 0.003 µM, 0.42 µM and 0.74 µM, which was 1.6- to 290-fold more potent than GDC-0941.
合成了三系列含有芳基亚甲基肼部分的4-吗啉硫烯并[3,2-d]嘧啶衍生物(11a–f, 13a–k 和 15a–h),并确认了它们的化学结构以及相对立体化学。合成的化合物对三种癌细胞系(H460, HT-29, MDA-MB-231)的细胞毒性进行了评估。大多数化合物表现出中等到显著的细胞毒性,并对一种或多种细胞系展现出高选择性,特别是化合物11c、13b、15f和15g与阳性对照相比显示出显著提高的细胞毒性,后者进一步在另外六种癌细胞系和一种正常细胞系中进行了评估。最有前景的化合物11c,含有3,4-亚甲基二氧苯基基团,对H460、HT-29和MDA-MB-231细胞系显示出显著细胞毒性,IC50值分别为0.003 µM、0.42 µM和0.74 µM,比GDC-0941的效力提高了1.6到290倍。
