sensitive to the nature of C-3substituents, with small alkyl substituents such as a gem-diethyl group improving the inhibitory potency when compared to gem-methyl benzyl or ethyl benzyl counterparts. 4-Oxo-β-lactams containing a heteroarylthiomethyl group on the para position of an N1-aryl moiety afforded highly potent and selective inhibition of HLE, even at a very low inhibitor to enzyme ratio, as shown

Achieving DipeptidylPeptidase 8 and 9 (DPP8/9) selectivity is a current challenge in chemical biology. Supported by activity-based protein profiling and X-ray crystallography, we disclose 4-oxo-β-lactams as potent, non-substrate-like nanomolar DPP8/9 inhibitors with different binding modes for DPP8/9, including an unprecedented targeting of an extended S2′ subsite in DPP8 and the best selectivity
