1.1.5.3 additional information screening and identification of cell-permeant small-molecule inhibitors of mGPDH (iGP) discovered through small-molecule screening. Structure-activity analysis identifies a core benzimidazole-phenyl-succinamide structure as being essential to inhibition of mGPDH while modifications to the benzimidazole ring system modulate both potency and off-target effects. The iGPs penetrate cellular membranes. Inhibitor selectivity, and effects of the inhibitors on kinetics of mGPDH, overview Mus musculus
