Oxazole derivatives are important medicinal compounds which are inhibitors of various enzymes such as NPP1, NPP2, NPP3, tyrosine kinase, dipeptidyl-peptidase IV, cyclooxygenase-2, and protein tyrosine phosphatase. In this study, an extensive range of new biologically active biphenyl oxazole derivatives was

Nonribosomal peptide synthetase (NRPS) oxidase (Ox) domains oxidize protein-bound intermediates to install crucial structural motifs in bioactive natural products. The mechanism of this domain remains elusive. Here, by studying indigoidine synthetase, a single-module NRPS involved in the biosynthesis of indigoidine

Bond breaking is a challenging problem in both experimental and theoretical chemistry, due to the transient nature and multi-configurational electronic structure of dissociating molecules. We use anion photodetachment to probe the diradical interactions in the ring-opening reaction of oxazole and
