Twenty-three 2-(substituted)phenyl-1,2,4-triazolo[1,5-a]pyridines have been synthesized by cycloadditison reaction between N-amino methylpyridinium mesitylenesulfonates and substituted benzonitriles under the presence of potassium hydroxide at room temperature. The structures of all products were confirmed by 1H NMR, MS and elemental analyses. The antitumor activities of these compounds were evaluated
在室温下,在氢氧化钾的存在下,N-氨基甲基吡啶基间苯磺酸磺酸盐与取代的苄腈之间的环加成反应已合成了二十三种2-(取代)苯基-1,2,4-三唑并[1,5- a ]吡啶。所有产物的结构均通过1 H NMR,MS和元素分析确认。通过MTT法在体外评估了这些化合物对人卵巢癌细胞系(HO-8910)的抗肿瘤活性。初步结果表明,化合物1E(IC 50 28μM)和化合物1瓦特(IC 50表现出更强的抗肿瘤比顺铂活性(IC31μM)5035μM)在体外。因此,1e和1w具有潜在的抗肿瘤活性,值得进一步研究。
