MedKoo CAT#: 407186

CAS#: 1652573-86-8

Description: PLX7683 is a paradox breaker. Paradox breakers overcame several known mechanisms of resistance to first-generation RAF inhibitors. Dissociating MAPK pathway inhibition from paradoxical activation might yield both improved safety and more durable efficacy than first-generation RAF inhibitors
