Small-molecular inhibitors of Ca²⁺-induced mitochondrial permeability transition (MPT) derived from muscle relaxant dantrolene

Bioorg Med Chem. 2012 Nov 1;20(21):6384-93. doi: 10.1016/j.bmc.2012.08.062. Epub 2012 Sep 14.

Abstract

A structure consisting of substituted hydantoin linked to a 5-(halophenyl)furan-2-yl group via an amide bond was identified as a promising scaffold for development of low-molecular-weight therapeutic agents to treat vascular dysfunction, including ischemia/reperfusion injury. Among the compounds synthesized, 5-(3,5-dichlorophenyl)-N-{2,4-dioxo-3-[(pyridin-3-yl)methyl]imidazolidin-1-yl}-2-furamide (17) possessed the most potent inhibitory activity against Ca(2+)-induced mitochondrial swelling. The structural development, synthesis and structure-activity relationship of these compounds are described.
