Novel pyrrolopyrazine derivatives were synthesized according to a very simple protocol starting from N-propargylated-2-acyl-pyrroles. These derivatives were obtained in good to excellent yields (68–94%) in the presence of ammonium acetate and Cs2CO3, and then subjected to cytotoxicity testing against glioblastoma cell line T98G. Among the tested molecules, those that cause 68.9%, 59.1%, and 37.5% cell
根据非常简单的方案,从N-炔丙基化-2-酰基-吡咯开始合成新的吡咯并吡嗪衍生物。这些衍生物在乙酸铵和Cs 2 CO 3的存在下以良好至极好的收率(68–94%)获得,然后针对成胶质细胞瘤细胞系T98G进行了细胞毒性测试。在测试的分子中,那些导致68.9%,59.1%和37.5%细胞死亡的分子被鉴定为先导化合物。结构-活性关系(SAR)研究表明,构象,π-π相互作用和卤素键可能对效率很重要。最后,对吡咯并吡嗪衍生物的理论ADMET研究表明,药代动力学阶段是合适的。 图形摘要
