Description: BMS-751324 is a clinical prodrug of p38α MAP kinase inhibitor. BMS-751324 is prodrug of BMS-582949. BMS-751324 was designed to address the issue of pH-dependent solubility and exposure associated with BMS-582949, a phase II clinical p38α MAP kinase inhibitor. BMS-751324 is featured with a carbamoylmethylene linked promoiety containing hydroxyphenyl acetic acid (HPA) derived ester and phosphate functionalities. BMS-751324 was not only stable but also water-soluble under both acidic and neutral conditions. BMS-751324 was effectively bioconverted into parent drug BMS-582949 in vivo by alkaline phosphatase and esterase in a stepwise manner, providing higher exposure of BMS-582949 compared to its direct administration, especially within higher dose ranges. In a rat LPS-induced TNFα pharmacodynamic model and a rat adjuvant arthritis model, BMS-751324 demonstrated similar efficacy to BMS-582949. Most importantly, it was shown in clinical studies that prodrug BMS-582949 was indeed effective in addressing the pH-dependent absorption issue associated with BMS-582949.
