A novel series of 2,4,6-trisubstituted 1,3,5-triazine derivatives bearing aryl hydrazone moiety were designed and synthesized under the guidance of scaffold hopping and bioisosterism from the autophagy inhibitor VLX600. The target compounds were evaluated for cytotoxicity against HT-29 by MTT assay with VLX600 as positive control. Then, ten potent target compounds (5c-5f, 5i-5r, 5s, 5t) were further
设计并合成了一系列带有芳基hop部分的2,4,6-三取代的1,3,5-三嗪衍生物,并在自噬抑制剂VLX600的支架跳跃和生物等排作用的指导下进行了合成。通过以VLX600作为阳性对照的MTT试验评估靶化合物对HT-29的细胞毒性。然后,针对两种癌细胞系H460和A549和一种正常细胞系WI-38,进一步评估了十种有效的目标化合物(5c-5f,5i-5r,5s,5t)。它们中的大多数对一种或多种细胞系表现出明显的细胞毒性。特别是,鉴定出了一种有前途的化合物5f,它对HT-29,H460和A549癌细胞系表现出最强的细胞毒性,IC50值分别为0.047μM,0.071μM和0.071μM,是后者的10到62倍比VLX600强(IC50 = 0.47μM,4.1μM,4。4μM)。还讨论了化合物的初步结构-活性关系(SAR)。
