A one-step synthesis of novel functionalized 3,4-dihydro-2H-pyrroles from 2-isocyanoacetates and readily synthesized acrylonitriles is reported. The reaction proceeds smoothly under mild conditions with high efficiency. The structures of two representative structures, 3a and 3m, were confirmed by X-ray crystallographic analysis.
manuscript we present the design, synthesis and biological evaluation of novel benzazole derived acrylonitriles bearing bicyclic heteroaromatic rings. Either benzimidazole, benzothiazole or imidazo[4,5-b]pyridine scaffolds are linked via acrylonitrile linker with different bicyclic heteroaromatics. All newly prepared are evaluated for their in vitro antiproliferative activity on 8 human cancer cells as well
在这份手稿中,我们介绍了新型苯唑衍生的带有双环杂芳环的丙烯腈的设计、合成和生物学评价。苯并咪唑、苯并噻唑或咪唑并[4,5- b ]吡啶支架通过丙烯腈接头与不同的双环杂芳烃连接。所有新制备的都在 MTS 细胞毒性和在 2D 和 3D 测定格式上进行的 BrdU 增殖测定中评估了它们对 8 种人类癌细胞以及三种人类肺癌细胞系的体外抗增殖活性。除萘基取代的苯并咪唑衍生物13和苯并噻唑基取代的衍生物17外,大多数测试化合物的活性均较弱, 都是苯并咪唑衍生的丙烯腈。此外,作为一种有前途的化合物,已证明是咪唑并[4,5- b ]吡啶衍生物25和30,对A549细胞具有选择性活性。此外,测试了所有化合物对九种细菌菌株和酿酒酵母的抗菌活性。只有苯并[ b ]呋喃-2-基取代的苯并咪唑衍生物14表现出中等活性。
