A novel series of twenty 3-thiocyanato-1H-indoles, carrying diversification at positions N-1, C-2 and C-5 of the heterocyclic core, were synthesized; their antiproliferative activity against four human cancer cell lines (HL60, HEP-2, NCI-H292 and MCF-7) was evaluated, employing doxorubicin as positive control. Indole, N-methylindole and 2-(4-chlorophenyl)-N-methylindole demonstrated to be essentially
合成了一系列新的二十二十个3-硫代氰基-1 H-吲哚,它们在杂环核的N-1,C-2和C-5位上具有多样性。使用阿霉素作为阳性对照,评估了它们对四种人类癌细胞系(HL60,HEP-2,NCI-H292和MCF-7)的抗增殖活性。吲哚,Ñ甲基吲和2-(4-氯苯基) - ñ甲基吲证明是基本上无活性的,而他们的几个同类的3-氰硫基1 ħ -indoles显示良好至效力优秀水平(IC 50 ≤6μM) ,同时不溶血。 N-苯基-3-硫氰酸根-1 H-吲哚和1-甲基-2-(4-氯苯基)-3-硫氰酸根-1 H-吲哚对所有细胞系表现出良好至高的效力。另一方面,N-(4-氯苯基)-,2-(4-氯苯基)-和2-苯基-3-硫代氰基-1 H-吲哚衍生物对测试细胞系的活性略低。 总体而言,这些结果表明,可以适当地修饰吲哚-3-硫氰酸酯基序以提供高度细胞毒性的化合物,并且可以将取代的吲哚用作对更有效的化合物有用的支架。
