The synthesis and structure–activity relationship of pyridazinones as glucan synthase inhibitors
摘要:
A structure-activity relationship study of the lead 5-[4-(benzylsulfonyl) piperazin-1-yl]-4-morpholino-2- phenyl-pyridazin-3(2H)-one 1 has resulted in the identification of 2-(3,5-difluorophenyl)-4-(3-fluorocyclopentyloxy)- 5-[4-(isopropylsulfonyl) piperazin-1-yl]-pyridazin-3(2H)-one 11c as a beta- 1,3-glucan synthase inhibitor. Compound 11c exhibited significant efficacy in an in vivo mouse model of Candida glabrata infection. (C) 2011 Elsevier Ltd. All rights reserved.
