from 0.071 to 0.303 μM. A mechanisticstudy revealed that compound 6e induced apoptosis on A498 cell line by 38.02% compared to 1.64% in control. This apoptotic effect was supported by an 8.58-fold increase in the level of caspase-3 compared to the control cells. Additionally, compound 6e inhibited A498 cell growth mostly at the S phase. Furthermore, molecular modeling studies showed that compound 6e
合成了一系列新的二苯甲酮腙衍生物并评估了它们的抗增殖活性。缩氨基硫脲衍生物5c和胍腙衍生物6d-f对 A498 肾癌细胞具有有效的抗增殖活性,IC 50分别为 14.5、0.28、0.30 和 0.3 μM。化合物5c、6d、6e和6f显示出对组织蛋白酶 L 和组织蛋白酶 B 的抑制活性(IC 50范围为 0.071 至 0.303 μM。机理研究表明化合物6e与对照中的 1.64% 相比,A498 细胞系诱导凋亡 38.02%。与对照细胞相比,caspase-3 水平增加了 8.58 倍,从而支持了这种凋亡效应。此外,化合物6e主要在 S 期抑制 A498 细胞生长。此外,分子模型研究表明,化合物6e通过疏水性氢键相互作用与必需氨基酸相互作用,因此与组织蛋白酶 L 和组织蛋白酶 B 结合位点具有良好的拟合。因此,化合物 6e 可被认为是一种有前途的抗癌先导化合物,值得进一步探索/优化作为通过组织蛋白酶抑制的抗增殖剂。

examine their effect on both prostaglandin (PG) production and neutrophils recruitment. The thiazole derivatives displayed a potent effect in terms of reducing ear edema. The analysis suggested that the presence of 4-phenyl-2-hydrazinothiazole and the absence of C4′-OCH3 on the benzophenonederivative structure are strongly related to the inhibition of PG production. In addition, the derivatives 2e, 3a and
