Isocytosine-based inhibitors of xanthine oxidase: Design, synthesis, SAR, PK and in vivo efficacy in rat model of hyperuricemia
摘要:
Structure-activity relationship studies were carried out for lead generation following structure-guided design approach from an isocytosine scaffold identified earlier for xanthine oxidase inhibition. A 470-fold improvement in in vitro IC50 was obtained in the process. Five most potent compounds with nanomolar IC50 values were selected for pharmacokinetics and in vivo experiments. The best compound showed good in vivo activity when administered intraperitoneally but was not active by oral route. The results suggest that improvement in oral exposure could improve the in vivo efficacy of this series. (C) 2012 Elsevier Ltd. All rights reserved.

2-amino-5-bromo-6-phenyl-4(3H)-pyrimidinone. An analogue study incorporating a series of 2-amino-5-substituted-6-arylpyrimidinones revealed that the most potent interferon inducers were mono- and difluorophenyl analogues. These same analogues were also potent antiviral agents against Semliki Forest virus and herpes simplex type 1. In addition the monomethoxyphenyl analogues were potent antiviral agents but weak interferon
