Resistance. mechanisms include the acquisition of secondary FLT3 mutations and pr otective stromal. WebJun 1, 2015 · Significance: We report the first cocrystal structure of FLT3 with a kinase inhibitor, elucidating the structural mechanism of resistance due to the gatekeeper F691L mutation. PLX3397 is a novel FLT3 inhibitor with in vitro activity against this mutation but is vulnerable to kinase domain mutations in the FLT3 activation loop.
