In this study, some pyrazolone-based Schiff base derivatives 2a-e (except 2a) were synthesized for the first time and structurally illuminated by some spectroscopic techniques (1H, 13C NMR, FT-IR) and elemental analysis. All synthesized molecules were screened for their anticancer and antioxidant activities, as well as AChE, BChE, and tyrosinase inhibitory properties. The obtained results exhibited
本研究首次合成了一些基于吡唑啉酮的席夫碱衍生物2a-e(2a除外),并通过一些光谱技术(1 H, 13 C NMR, FT-IR)和元素分析进行了结构阐明。筛选所有合成分子的抗癌和抗氧化活性,以及 AChE、BChE 和酪氨酸酶抑制特性。所得结果表明化合物1b (IC 50 = 9.497 μM)和2a (IC 50 = 30.49 μM) 显着降低 HeLa 细胞的增殖。另一方面,用吖啶橙/碘化丙啶双染色研究了这两种化合物的细胞凋亡作用。用这两种化合物处理的分子的凋亡细胞比率确定为 60% 和 64%。化合物2b (IC 50 = 17.95 ± 0.47 μM)在ABTS测定中被确定为非常有活性的物质。 在铜还原抗氧化能力 (CUPRAC) 测定中,化合物2e (A 0.5 = 43.75 ± 0.62 μM) 表明与标准化合物α -TOC (A 0.5 = 50.58 ± 0
