PubMed Abstract:
Following from the evaluation of different types of electrophiles, combined modeling and crystallographic analyses are used to generate potent boronic acid based inhibitors of a penicillin binding protein. The results suggest that a structurally informed approach to penicillin binding protein inhibition will be useful for the development of both improved reversibly binding inhibitors, including boronic acids, and acylating inhibitors, such as β-lactams.
