Synthesis of imine-pyrazolopyrimidinones and their mechanistic interventions on anticancer activity
摘要:
Design, synthesis and anticancer activity of a series of imine-pyrazolopyrimidinones is reported for the first time. Compounds 9d, 9n and 9o in the series show encouraging in vitro anticancer activity with low micromolar IC50 values against prostate (PC3) and breast (MCF7) cancer cell lines. Some notions about structure-activity relationships and plausible mechanism of biological activity are presented. (C) 2013 Elsevier Ltd. All rights reserved.
由适当的5-氨基吡唑-4-羧酸酯制备1-取代的5-氨基吡唑-4-羰基叠氮化物。酰基叠氮化物经历Curtius重排,然后用醇淬灭以形成相应的氨基甲酸酯。通过催化氢解解封1-取代的5-氨基-4-苄氧基羰基氨基吡唑,得到所需的4,5-二氨基吡唑。立即将这些4,5-二氨基吡唑与乙二醛缩合,得到1-取代的吡唑并[3,4- b ]吡嗪。
