Methionine aminopeptidase type 2 catalyzes the removal of the amino-terminal methionine from newly translated polypeptides and has been shown to be a promising target for anti-angiogenesis and anticancer drugs. We describe a novel μARCS HTS method to identify inhibitors of this target utilizing porous matrices to introduce reagents throughout the assay. A library of 250,000 compounds was screened and compounds with IC50 values of less than 10μM were identified. These compounds may serve as initial lead molecules for further medicinal chemistry optimization.
