Structure–activity relationships of the peptide deformylase inhibitor BB-3497: modification of the P2′ and P3′ side chains
摘要:
Structural modifications to the peptide deformylase inhibitor BB-3497 are described. In this paper, we describe the initial SAR around this lead for modifications to both the P2' and P3' side chains. Enzyme inhibition and antibacterial activity data revealed that a variety of substituents are tolerated at the P2' and P3' positions of the inhibitor backbone. The data from this study highlights the potential for modification at the P2' and P3' positions to optimise the physicochemical properties. (C) 2003 Elsevier Ltd. All rights reserved.
β-Methanesulfonyl-L-valine as a novel, unnatural amino acid surrogate for P2 in the design of HIV protease inhibitors.
摘要:
beta-Methanesulfonyl-L-valine as a surrogate for asparagine and valine was designed, synthesized, and characterized. A representative compound 1 showed IC50 of 4.9 nM.
