Human Methionine Aminopeptidase-2 Complexed with SB-587094

OverviewOverview

High-throughput screening for inhibitors of the human metalloprotease, methionine aminopeptidase-2 (MetAP2), identified a potent class of, 3-anilino-5-benzylthio-1,2,4-triazole compounds. Efficient array and, interative synthesis of triazoles led to rapid SAR development around the, aniline, benzylthio, and triazole moeities. Evaluation of these analogs in, a human MetAP2 enzyme assay led to the identification of several, inhibitors with potencies in the 50-100 picomolar range. The deleterious, effects on inhibitor potency by methylation of the anilino-triazole, nitrogens, as well as the X-ray crystal structure of triazole 102 bound in, the active site of MetAP2, confirm the key interactions between the, triazole nitrogens, the active site cobalt atoms, and the His-231, side-chain. The structure has also provided a rationale for interpreting, SAR within the triazole series. Key aniline (2-isopropylphenyl) and sulfur, substituents (furanylmethyl) identified in the SAR studies led to the, identification of potent inhibitors (103 and 104) of endothelial cell, proliferation. Triazoles 103 and 104 also exhibited dose-dependent, activity in an aortic ring tissue model of angiogenesis highlighting the, potential utility of MetAP2 inhibitors as anticancer agents.
