MLN518 is a novel, oral, small molecule designed to inhibit type III receptor tyrosine kinases, including FLT3, (platelet-derived growth-factor receptor) PDGFR and c-KIT. Tyrosine kinases are enzymes involved in several cellular processes and are known to be activated in cancer cells to drive tumor growth. AML patients with FLT3 mutations experience earlier disease relapse and shorter survival rates compared to patients without these mutations. Approximately 25 to 30 percent of all adult AML patients have a mutation of the FLT3 gene. The use of MLN518 to treat AML has been granted fast-track status by the U.S. Food and Drug Administration. Phase I/II trials are underway.


Investigated for use/treatment in leukemia (myeloid).

Mechanism Of Action

MLN518 inhibits tyrosine kinases; Specifically, it is selective for FLT3, KIT, and platelet-derived growth-factor receptor (PDGFR).


MLN518 is a novel quinazoline-based small molecule inhibitor of the FLT3, KIT, and platelet-derived growth-factor receptor (PDGFR) tyrosine kinases with that has been shown to have great efficacy in murine models of FLT3 ITD-positive leukemia. Experiments with mice demonstrate that at effective concentrations, MLN518 has mild toxicity toward normal hematopoiesis for FLT3 ITD-positive leukemia. MLN518 has also been shown to preferentially inhibit the growth of blast colonies from FLT3 ITD-positive as compared to ITD-negative patients with AML, without significantly affecting colony formation by normal human progenitor cells.

Chemical Classification

This compound belongs to the class of organic compounds known as n-arylpiperazines. These are organic compounds containing a piperazine ring where the nitrogen ring atom carries an aryl group.
