for broad and potent anti-cancer agents, a series of 5-phenyl-1H-pyrazol-3-yl 1(acyl)indoline-5-sulfonates (4) and 1-(1-(acyl)indolin-5-ylsulfonyl)-5-phenylpyrazolidin-3-ones (5) were prepared and evaluated for their cytotoxicity against six human cancer cell lines. Although the pyrazoles 4 or pyrazolidinones 5 showed relatively good activity, still they showed lesser activity in comparison to imidazolidinones
为了研究 4-phenyl-1-arylsulfonylimidazolidinones (2) 中
咪唑啉酮部分可能的等排替代,用于广泛有效的抗癌剂,一系列 5-phenyl-1H-pyrazol-3-yl 1(acyl)indoline-5 -
磺酸盐 (4) 和 1-(1-(acyl)indolin-5-ylsulfonyl)-5-phenylpyrazolidin-3-ones (5) 制备并评估了它们对六种人类癌
细胞系的细胞毒性。尽管
吡唑 4 或
吡唑烷酮 5 表现出相对较好的活性,但与
咪唑烷酮 2 相比,它们仍然表现出较低的活性。这些活性降低可以解释为氢键特征的变化和取代模式对五元环结构变化的影响分别从
咪唑烷酮 2 到
吡唑 4 和
吡唑烷酮 5。所以,
