Description: SAN50900, also known as FLT3-IN-3, is a potent and selective FLT3 inhibitor. SAN50900 displays nanomolar activity in biochem. assays and selectively blocks proliferation of AML cell lines harboring FLT3-​ITD mutations, whereas other transformed and normal human cells are several orders of magnitude less sensitive. SAN50900 was first reported in J Med Chem. 2018 May 10;61(9):3855-3869. (compd. 7d). This product has not formal name. For the convenience of scientific communication, we named it by combining its Inchi key (3 letters from the first letter of each section) with the last 5 digit of its CAS#) according to MedKoo Chemical Nomenclature (

Additional Information

FLT3 tyrosine kinase is a potential drug target in acute myeloid leukemia (AML) because patients with FLT3-​ITD mutations respond poorly to std. cytotoxic agents and there is a clear link between the disease and the oncogenic properties of FLT3. The MV4-​11 cells treated with 7d suppressed the phosphorylation of FLT3 and its downstream signaling pathways, with subsequent G1 cell cycle arrest and apoptosis. Addnl., a single dose of 7d in mice with s.c. MV4-​11 xenografts caused sustained inhibition of FLT3 and STAT5 phosphorylation over 48 h, in contrast to the shorter effect obsd. after administration of the ref. FLT3 inhibitor quizartinib.
