calcium-dependent protein kinase 1 (CDPK1) is a promising target for drug development against cryptosporidiosis. We report a series of low-nanomolar CDPK1 5-aminopyrazole-4-carboxamide (AC) scaffold inhibitors that also potently inhibit growth Correlation between anti-CDPK1 and growth inhibition, as previously reported for pyrazolopyrimidines, was not apparent. Nonetheless, lead AC compounds exhibited a substantial reduction of parasite burden in the neonatal mouse cryptosporidiosis model when dosed at 25 mg/kg.
钙依赖性蛋白激酶1(CDPK1)是抗隐孢子虫病药物开发的一个有前景的靶点。我们报告了一系列低纳摩尔浓度的CDPK1 5-氨基吡唑-4-甲酰胺(AC)支架抑制剂,它们也能有效抑制生长。与之前报道的吡唑并嘧啶不同,抗CDPK1作用与生长抑制之间的相关性并不明显。尽管如此,先导AC化合物在新生小鼠隐孢子虫病模型中以25 mg/kg给药时,寄生虫负荷显著降低。
