3,5-二氨基-4-(3-三氟甲基苯基二氮烯基)-1 H-吡唑被用作合成新型吡唑基杂环的起始支架,以研究其对三种人类癌细胞系增殖的影响。使用MTT分析法检测人肝癌细胞系(HepG-2),结肠癌细胞系(HCT-116)和人乳腺癌细胞系(MCF-7)。根据IR,1 H NMR,13表征合成的化合物13 C NMR,质谱数据和元素分析结果。细胞毒性测定结果表明,某些化合物对所有测试的细胞系均显示出有效的生长抑制作用,IC50值在0.64–7.73μg/ mL范围内。乳腺癌细胞被用于进一步的详细研究,以了解最有效化合物的细胞生长抑制和细胞凋亡诱导作用的机制。结果表明,化合物3a,10b和11aMCF-7细胞在细胞周期的G2 / M期停滞,并可能通过caspase-3依赖性途径诱导凋亡。最活跃的化合物对caspase 3活性位点的分子建模和结合模式分析进一步为它们的促凋亡作用提供了协同机制。为了探索
Pharmaceutical compositions and compounds are provided. The compounds of the invention demonstrate anti-proliferative activity, and may promote apoptosis in cells lacking normal regulation of cell cycle and death. In one embodiment of the invention, pharmaceutical compositions of the compounds in combination with a physiologically acceptable carrier are provided. The pharmaceutical compositions are useful in the treatment of hyperproliferative disorders, which disorders include tumor growth, lymphoproliferative diseases, angiogenesis. The compounds of the invention are substituted pyrazoles and pyrazolines.
Discovery, SAR study and ADME properties of methyl 4-amino-3-cyano-1-(2-benzyloxyphenyl)-1<i>H</i>-pyrazole-5-carboxylate as an HIV-1 replication inhibitor
screened our in-house library of pyrazole-based compounds to evaluate their in cellulo activity against HIV-1 replication. Two hits with very similar structures appeared from single and multiple-round infection assays to be non-toxic and active in a dose-dependent manner. Chemical expansion of their series allowed an in-depth and consistent structure–activity-relationship study (SAR) to be built. Further
受已知基于吡唑的 HIV 抑制剂的抗病毒活性的启发,我们筛选了我们内部的基于吡唑的化合物库,以评估它们在纤维素中对 HIV-1 复制的活性。从单轮和多轮感染测定中显示出具有非常相似结构的两个命中是无毒的并且以剂量依赖性方式具有活性。他们系列的化学扩展允许建立深入和一致的结构-活性-关系研究 (SAR)。进一步的 ADME 评估导致选择了 4-amino-3-cyano-1-(2-benzyloxyphenyl)-1 H-pyrazole-5-carboxylate 具有有利的药代动力学特征。最后,对其作用方式的检查表明,该化合物不属于三种主要的抗 HIV 药物,这是在病毒耐药性背景下最令人感兴趣的特征。
