Benzoxazole benzenesulfonamides as allosteric inhibitors of fructose-1,6-bisphosphatase
摘要:
A series of novel benzoxazole benzenesulfonamides was synthesized as inhibitors of fructose-1,6-bisphosphatase (FBPase-1). Extensive SAR studies led to a potent inhibitor, 53, with an IC50 of 0.57 mu M. Compound 17 exhibited excellent bioavailability and a good pharmacokinetic profile in rats. (C) 2006 Elsevier Ltd.

The synthesis of heterocycles relies heavily on diverse sigmatropic rearrangements triggered by the cleavage of X–Y (X, Y = C, O, N, S, I) bonds. However, a unified rearrangement approach for constructing heterocyclic libraries is highly desirable. Encouraged by computational analysis of [3,3]-sigmatropic rearrangements, we can now rapidly synthesize oxa-heterocycles by treating N-phenoxyacetamides
