Starting from the 3,5-dimethyl pyrazole ring and acetophenone derivatives, five different N-propargylated C-3 substituted pyrazoles were obtained. These derivatives were reacted with different amine derivatives using Cs2CO3 in methanol and 11 different pyrazolo [1,5-a] pyrazine-4(5H)-one derivatives were obtained, which are not found in the literature. The cytotoxic effects of these derivatives in the A549
摘要 从 3,5-二甲基吡唑环和苯乙酮衍生物开始,得到了五种不同的 N-炔丙基化 C-3 取代吡唑。这些衍生物在甲醇中使用Cs 2 CO 3与不同的胺衍生物反应,得到了11种不同的吡唑并[1,5-a]吡嗪-4(5 H )-one衍生物,这些衍生物在文献中没有发现。研究了这些衍生物在 A549 细胞系中的细胞毒性作用。发现两种衍生物的 160 µM 浓度可将细胞死亡率提高至 50%,而两种衍生物可将细胞死亡率提高高达 40%。构效关系 (SAR) 研究揭示了具有长烷基链的酰胺基团和具有p -CF 3的苯环组对于效率可能很重要。通过对吡唑并吡嗪衍生物的理论 ADMET 研究,预计药代动力学阶段是合适的。 图形摘要
