Synthesis, biological evaluation and molecular modelling of sulfonohydrazides as selective PI3K p110α inhibitors
摘要:
A series of 2-methyl-5-nitrobenzenesulfonohydrazides were prepared and evaluated as inhibitors of PI3K. An isoquinoline derivative shows good selectivity for the p110 alpha isoform over p110 beta and p110 delta, and also demonstrates good in vitro activity in a cell proliferation assay. Molecular modelling provides a rationalisation for the observed SAR. (c) 2007 Elsevier Ltd. All rights reserved.

Oxidative radical cyclisation using Bu3SnH has been used for the synthesis of [1,2-c]-fused imidazoles and [1,2-a]-fused pyrroles from imidazolecarbaldehydes and acylpyrroles respectively. The intermediate nucleophilic N-alkyl radicals cyclise onto imidazole and pyrrole rings followed by oxidative re-aromatisation. (C) 1997 Elsevier Science Ltd.
