In search of new active molecules against MCF-7, A549 and HepG2, tetrazole based pyrazoline and isoxazoline derivatives under both conventional and ultrasonic irradiation method were designed and efficiently synthesized. Structures of newly synthesized compounds 5a-h and 6a-h were characterized by 1H NMR, 13C NMR, MS and elemental analysis. Several derivatives were found to be excellent cytotoxic against
为寻找针对MCF-7,A549和HepG2的新活性分子,设计并有效合成了四唑基吡唑啉和异恶唑啉衍生物。通过1 H NMR,13 C NMR,MS和元素分析对新合成的化合物5a-h和6a-h的结构进行表征。已发现几种衍生物对MCF-7,A549和HepG2细胞系具有优异的细胞毒性,其特征在于IC 50值较低(0.78-3.12 µg / mL)。化合物5b和5c证明了与CA-4相当的抗增殖作用。蛋白质印迹分析表明,报道的化合物在可溶性级分中积累了更多的微管蛋白。对接研究表明,这些化合物的结合在微管蛋白的秋水仙碱位点模仿。体外研究表明,基于四唑的吡唑啉和异恶唑啉可能具有进一步开发新型治疗剂的理想结构要求。
