-pyrazol-5-yl- N , N -dimethylformamidines and pyrazolyl-2-azadienes. All of the starting materials and resulting products were tested against NCI-H226, NPC-TW01, and Jurkat cancer cells to evaluate their antiproliferative activities. 1 H -Pyrazol-5-yl- N , N -dimethylformamidines 2b , 2c , and 2d were most potent with IC50 values in low micromolar range. The formyl group at C-4 position and the grafted amidinyl
摘要 成功开发了化学选择性微波辅助的酰胺化反应,合成了1 H- 吡唑-5-基 -N , N- 二甲基甲am和吡唑基-2-氮杂二烯。对所有起始原料和所得产品进行了针对NCI-H226,NPC-TW01和Jurkat癌细胞的测试,以评估其抗增殖活性。1 H- 吡唑-5-基 -N , N- 二甲基 甲am 2b , 2c 和 2d 对IC 50最有效低摩尔浓度范围内的值。C-4位的甲酰基和吡唑分子主核中的接枝a基对于抑制活性是必需的。 图形概要
