cells while compound 6e showed dilated blood vessels with more apoptotic cells if compared with NAC. Caspase-3 inhibition assay revealed that compounds 6a, 6b and 6d weaken caspase-3 expression to an extent higher than NAC (1.063, 0.430, 0.731 and 1.115, respectively). Docking studies with caspase-3 revealed that most of the tested compounds showed good binding with the enzyme especially for compound
我们报告了新的喹啉-2-一/吡唑杂化物的合成及其抗凋亡活性。使用N-乙酰半胱氨酸(NAC)作为抗凋亡参考,研究了减少I / R诱导的大鼠结肠组织损伤的效果。与模型组相比,化合物6a,6c和6f的氧化应激参数MDA,SOD,GSH和NOx表现出显着改善,并且比参考NAC(N-乙酰半胱氨酸)更大,而化合物6d和6e与模型组相比显示出较弱的抗氧化活性。参考NAC。此外,与模型组相比,化合物6a,6c和6f显示出炎性介质TNFα和CRB的降低显着大于NAC,尤其是化合物6c,其与conc 2.13mg / dL的NAC相比发现CRB为1.90(mg / dL)。此外,对所有目标化合物进行了结肠组织病理学研究,结果表明,与NAC相比,化合物6a和6f的H&E切片显示明显的正常结肠细胞,而化合物6e显示的血管扩张,凋亡细胞更多。Caspase-3抑制分析表明,化合物6a,6b和6d减弱caspase-3的表达的程度高于NAC(分别为1
