A small library of highly functionalized phenylaminopyrazoles, bearing different substituents at position 1, 3, and 4 of the pyrazole ring, was prepared by the one-pot condensation of active methylene reagents, phenylisothiocyanate, and substituted hydrazine (namely, methyl- and benzyl-hydrazine). The identified reaction conditions proved to be versatile and efficient. Furthermore, the evaluation of
通过活性亚甲基试剂、异硫氰酸苯酯和取代的肼(即甲基-和苄基-肼)。确定的反应条件被证明是通用和有效的。此外,对替代逐步方案的评估影响了一锅法的化学和区域选择性结果。两个N的化学性质-甲基吡唑异构体,被选为整个系列的原型,通过核磁共振和质谱研究明确鉴定。此外,半经验计算为两种异构体的不同色谱行为提供了结构依据。制备的四取代苯氨基吡唑在一组癌症和正常细胞系的基于细胞的测定中进行了测试。测试的化合物对选定的细胞系没有表现出任何细胞毒性作用,因此支持了它们的药学潜力。
