Petra, osiris, and molinspiration together as a guide in drug design: Predictions and correlation structure/antibacterial activity relationships of new N-sulfonyl monocyclic β-lactams

We report in this article the design and calculated molecular properties of 18 new mono-cyclic β-lactams 4-21, on the basis of one hypothetical antibacterial pharmacophore structure designed to interact with both of Gram-positive bacteria and Gram-negative bacteria. The in vitro biological evaluation of these compounds allowed us to point out new potential non-nucleoside hits, with MIC values in the range of 2-8 μg/mL active against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Pseudomonas aeruginosa. A correlation structure/antibacterial activities relationship of these monocyclic β-lactams is described. Supplemental materials are available for this article.
