Toluidinesulfonamide Hypoxia-induced Factor 1 Inhibitors: Alleviating Drug-drug Interactions through Use of PubChem Data and Comparative Molecular Field Analysis Guided Synthesis

Inhibitors of hypoxia-inducible factor 1 (HIF-1) represent promising anticancer therapeutics. We have identified a series of potent toluidinesulfonamide HIF-1 inhibitors. However, the series was threatened by a potential liability to inhibit CYP2C9 which could cause dangerous drug-drug interactions when being coadministered with other drugs. We used structure-activity data from the PubChem database to develop a topomer CoMFA model that guided the design of novel sulfonamides with high selectivity for HIF-1 over CYP2C9 inhibition.
