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 antitumoractivities 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。

enhanced mouse liver microsome stability. The structure–activity relationship for EphB3 inhibition of both heterocyclicseries was similar. Kinase inhibitory activity was also demonstrated for representative analogs in cell culture. An analog (32, LDN-211904) was also profiled for inhibitory activity against a panel of 288 kinases and found to be quite selective for tyrosine kinases. Overall, these studies
吡唑并[1,5- a ]吡啶的 2-氯苯胺衍生物的构效关系研究表明,通过保留 2-氯苯胺并向 5吡唑并[1,5- a ]吡啶的-位。此外,用咪唑并[1,2- a ]吡啶替代吡唑并[1,5- a ]吡啶具有良好的耐受性,并导致小鼠肝微粒体稳定性增强。EphB3 抑制两种杂环系列的构效关系相似。细胞培养中的代表性类似物也证明了激酶抑制活性。一个模拟 ( 32, LDN-211904) 还分析了对一组 288 种激酶的抑制活性,发现对酪氨酸激酶具有很高的选择性。总体而言,这些研究为检查 EphB3 受体的体外、细胞和潜在的体内激酶依赖性功能提供了有用的分子探针。
