MRX-2843

SKU: orb1308007

Description

MRX-2843 (UNC2371) is a potent, orally bioavailable small molecule inhibitor targeting MERTK and FLT3 with IC50 values of 1.3 nM and 0.64 nM, respectively. It is a valuable research tool for studying oncology, particularly in acute myeloid leukemia (AML), and has demonstrated activity in both cellular assays and in vivo tumor models.

Bioactivity

• Target IC50:
  FLT3:0.64 nM|MerTK:1.3 nM
• In Vivo:
  In murine orthotopic xenograft models, once-daily oral therapy prolonged survival 2- to 3-fold over that of vehicle-treated controls. Additionally, MRX-2843 retained activity against quizartinib-resistant FLT3-ITD-mutant proteins with clinically relevant alterations at the D835 or F691 loci and prolonged survival in xenograft models of quizartinib-resistant AML. Together, these observations validate MRX-2843 as a translational agent and support its clinical development for the treatment of AML.
• In Vitro:
  MRX-2843, a type 1 small-molecule tyrosine kinase inhibitor that abrogates activation of both MERTK and FLT3 and their downstream effectors. MRX-2843 treatment induces apoptosis and inhibits colony formation in AML cell lines and primary patient samples expressing MERTK and/or FLT3-ITD, with a wide therapeutic window compared with that of normal human cord blood cells.
