Abstract

The present study describes our continued efforts in the discovery and characterization of a series of 2-sulfonamidebenzamides as allosteric modulators of MrgX1. MrgX1 has been shown to be an attractive target as a nonopioid receptor for the potential treatment of chronic pain. Working from our original compound, ML382, and utilizing iterative medicinal chemistry, we have identified key halogen substituents that improve MrgX1 potency by ∼8-fold. In addition, we have evaluated the compounds in Tier 1 drug metabolism and pharmacokinetics assays and have identified key compounds that impart improved potency and microsomal stability.
