  Development of 5-Aminopyrazole-4-carboxamide-based Bumped-Kinase Inhibitors for Cryptosporidiosis Therapy

  摘要：

  Cryptosporidium is a leading cause of pediatric diarrhea worldwide. Currently, there is neither a vaccine nor a consistently effective drug available for this disease. Selective 5-aminopyrazole-4-carboxamide-based bumped-kinase inhibitors (BKIs) are effective in both in vitro and in vivo models of Cryptosporidium parvum. Potential cardiotoxicity in some BKIs led to the continued exploration of the 5-aminopyrazole-4-carboxamide scaffold to find safe and effective drug candidates for Cryptosporidium. A series of newly designed BKIs were tested for efficacy against C. parvum using in vitro and in vivo (mouse infection model) assays and safety issues. Compound 6 (BKI 1708) was found to be efficacious at 8 mg/kg dosed once daily (QD) for 5 days with no observable signs of toxicity up to 200 mg/kg dosed QD for 7 days. Compound 15 (BKI 1770) was found to be efficacious at 30 mg/kg dosed twice daily (BID) for 5 days with no observable signs of toxicity up to 300 mg/kg dosed QD for 7 days. Compounds 6 and 15 are promising preclinical leads for cryptosporidiosis therapy with acceptable safety parameters and efficacy in the mouse model of cryptosporidiosis.

  We previously discovered compounds based on a 5-aminopyrazole-4-carboxamide scaffold to be potent and selective inhibitors of CDPK1 from T. gondii. The current work, through structure-activity relationship studies, led to the discovery of compounds (34 and 35) with improved characteristics over the starting inhibitor 1 in terms of solubility, plasma exposure after oral administration in mice, or efficacy on parasite growth inhibition. Compounds 34 and 35 were further demonstrated to be more effective than 1 in a mouse infection model and markedly reduced the amount of T. gondii in the brain, spleen, and peritoneal fluid, and 35 given at 20 mg/kg eliminated T. gondii from the peritoneal fluid.
