Kinetic Compatibility as a Predictor of PTP1B Inhibitor Combination Outcomes: An Integrated Experimental and Computational Study. (PubMed, ChemMedChem) - Aug 21, 2026 - "Although chlorogenic acid, suramin, ursolic acid, and the glycyrrhetinic acid derivative FC122 are individually known PTP1B inhibitors, no study has systematically characterized how mechanistic diversity determines the pharmacological outcome of their combinations. For the first time, the MD-AMBER-Umbrella-COM protocol was applied to generate a comparative membrane permeability profile for mechanistically diverse PTP1B inhibitors, proposing a permeability order (SUR > FC122 > CGA ≈ UA). These results suggest that kinetic compatibility is a more reliable predictor of promising inhibitor combinations than binding-site geography alone, and they offer a rational framework for designing multisite PTP1B inhibition strategies in type 2 diabetes mellitus."
