Tandutinib(MLN518)

Tandutinib (MLN518, CT53518) is a potent FLT3 antagonist with IC50 of 0.22 μM, also inhibits PDGFR and c-Kit, 15 to 20-fold higher potency for FLT3 versus CSF-1R and >100-fold selectivity for the same target versus FGFR, EGFR and KDR. IC50 value: 0.22 uM [1]Target: Flt3; PDGFRβ; c-Kitin vitro: Tandutinib has little activity against EGFR, FGFR, KDR, InsR, Src, Abl, PKC, PKA and MAPKs. Tandutinib inhibits IL-3-independent cell growth and FLT3-ITD autophosphorylation with an IC50 of 10-100
Tandutinib is an N-arylpiperazine that is piperazine in which the hydrogen attached to the nitrogen at position 1 is replaced by a 6-methoxy-7-[3-(piperidin-1-yl)propoxy]quinazolin-4-yl group, while the hydrogen attached to the nitrogen at position 4 is replaced by a (p-isopropoxyphenyl)aminocarbonyl group. Tandutinib is an inhibitor of tyrosine kinases FLT3, PDGFR and KIT. It has a role as an antineoplastic agent and an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor. It is a N-carbamoylpiperazine, a N-arylpiperazine, a member of quinazolines, a member of piperidines, an aromatic ether, a tertiary amino compound and a member of phenylureas.|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.|Tandutinib is a piperazinyl quinazoline receptor tyrosine kinase inhibitor with antineoplastic activity. Tandutinib inhibits the autophosphorylation of FLT3 (FMS-Like Tyrosine kinase-3), c-KIT and PDGF (platelet-derived growth factor) receptor tyrosine kinases, thereby inhibiting cellular proliferation and inducing apoptosis.
