The development of first Staphylococcus aureus SplB protease inhibitors: Phosphonic analogues of glutamine
摘要:
Produced by Staphylococcus aureus, SplB belongs to the chymotrypsin-like serine protease family. Since the biological role of SplB protease is unknown, the design and application of its specific inhibitors may help to reveal the function of this enzyme. Until now no SplB inhibitors have been reported. Herein, we present the design and synthesis of novel a-aminophosphonic analogues of glutamine, as well as their peptidyl derivatives. The inhibitory effects of these compounds towards the newly discovered SplB serine protease from S. aureus are characterized. We have also investigated the influence of aromatic ester substituents on inhibitory potency towards SplB. One of the compounds-Cbz-Glu-Leu-Gln(P)(OC6H4-4-O-CH3)(2)-displayed an apparent second-order inhibition rate value of 1400 M(-1)s(-1). (C) 2012 Elsevier Ltd. All rights reserved.

the development of new bisubstrate inhibitors that include electron-deficient aromatic groups to mimic the nicotinamide moiety. In addition, a trans-alkene linker was found to be optimal for connecting the substrate and cofactor mimics in these inhibitors. The most potent NNMT inhibitor identified exhibits an IC50 value of 3.7 nM, placing it among the most active NNMT inhibitors reported to date. Complementary

potential therapeutic target. By structural modification of a lead NNMT inhibitor previously developed in our group, we prepared a diverse library of inhibitors to probe the different regions of the enzyme's active site. This investigation revealed that incorporation of a naphthalene moiety, intended to bind the hydrophobic nicotinamide binding pocket via π-π stacking interactions, significantly increases
