  Pyridinylpyrimidines selectively inhibit human methionine aminopeptidase-1

  摘要：

  Cellular protein synthesis is initiated with methionine in eukaryotes with few exceptions. Methionine aminopeptidases (MetAPs) which catalyze the process of N-terminal methionine excision are essential for all organisms. In mammals, type 2 MetAP (MetAP2) is known to be important for angiogenesis, while type 1 MetAP (MetAP1) has been shown to play a pivotal role in cell proliferation. Our previous high-throughput screening of a commercial compound library uncovered a novel class of inhibitors for both human MetAP1 (HsMetAP1) and human MetAP2 (HsMetAP2). This class of inhibitors contains a pyridinylpyrimidine core. To understand the structure-activity relationship (SAR) and to search for analogues of 2 with greater potency and higher HsMetAP1-selectivity, a total of 58 analogues were acquired through either commercial source or by in-house synthesis and their inhibitory activities against HsMetAP1 and HsMetAP2 were determined. Through this systematic medicinal chemistry analysis, we have identified (1) 5-chloro-6-methyl-2-pyridin-2-ylpyrimidine as the minimum element for the inhibition of HsMetAP1; (2) 5'-chloro as the favored substituent on the pyridine ring for the enhanced potency against HsMetAP1; and (3) long C4 side chains as the essentials for higher HsMetAP1-selectivity. At the end of our SAR campaign, 25b, 25c, 26d and 30a-30c are among the most selective and potent inhibitors of purified HsMetAP1 reported to date. In addition, we also performed crystallographic analysis of one representative inhibitor (26d) in complex with N-terminally truncated HsMetAP1. (C) 2013 Elsevier Ltd. All rights reserved.
