Description:

WARNING: This product is for research use only, not for human or veterinary use.

4SC-203 is a multikinase inhibitor with potential antineoplastic activity. Multikinase inhibitor 4SC-203 selectively inhibits FMS-related tyrosine kinase 3 (FLT3/STK1), FLT3 mutated forms, and vascular endothelial growth factor receptors (VEGFRs). This may result in the inhibition of angiogenesis and cell proliferation in tumor cells in which these kinases are upregulated. FLT3 (FLK2), a class III tyrosine kinase receptor, is overexpressed or mutated in most B lineage and acute myeloid leukemias (AML). VEGFRs, tyrosine kinase receptors, are overexpressed in a variety of tumor cell types and play key roles in angiogenesis.

More Info
4SC-203 is a novel multi-target kinase inhibitor. In preclinical testing the compound has shown unique and strong selectivity against a set of kinases including FLT3, FLT3 mutants and VEGF-receptors. FLT3 is involved in the growth and maturation of normal blood cells. With the inhibition of VEGF receptor tyrosine kinases, 4SC-203 may also inhibit angiogenic processes – i.e. the formation of vascular structures that provide nutrition for tumours enabling them to grow rapidly – and could therefore also be applicable in solid cancer types. 4SC-203 was jointly developed with ProQinase GmbH, a company based in Freiburg, Germany. The molecule has successfully completed a randomised, double-blind, placebocontrolled Phase I study in healthy volunteers which demonstrated the safety, tolerability and pharmacokinetics of this intravenously delivered compound.
