Cell cycle analysis of SNB-75 cells treated with compound 15 showed cell cycle arrest at G2/M phase. Further, the assay of levels of active caspase-3 and caspase-9 was investigated. Moreover, Molecular docking of compounds, 9d, 10b, 12, 15, 16, monastrol and mon-97 was performed to study the interaction between inhibitors and the kinesin spindle protein allosteric binding site.
设计并合成了二十一个21位3,4-二氢嘧啶衍生物,该化合物在2位,3位和5位带有不同的取代基,在4位带有杂环1,3-苯并二恶唑,并作为monastrol类似物合成。根据NCI(美国)方案,筛选了新合成的化合物对60种癌细胞系的细胞毒活性。化合物10b和15显示出对大多数细胞系的最佳抗肿瘤活性。随后以5剂模式测试化合物15,并在GI50水平下显示出对CNS,前列腺和白血病亚组的高选择性,选择性比分别为22.30、15.38和12.56。化合物9d,10b,12、15和16对驱动蛋白酶的IC50分别为3.86±0.12、10.70±0.35、3.95±0.12、4.36±0.14和14.07±0.45μM,而原型化合物monastrol,报告的IC50值为20±0.42μM。与阿霉素(IC50 = 11.34±0.44 µM / ml)相比,测试化合物中针对正常细胞系(HEK 293)最安全的化合物为10b,IC50值为62
