Structure Elucidation of Antibiotics

Methods Mol Biol. 2023:2601:97-122. doi: 10.1007/978-1-0716-2855-3_6.

Abstract

To date, there are hundreds of characterized natural products with antibacterial activity against pathogenic bacteria, and several have become bonafide antibiotic drugs. The development of antibacterial natural products into antibiotic drugs, both in the past and in the future, hinges upon an accurate description of the exact chemical structure of the compound. Bolstered by some form of mass spectrometry (MS), nuclear magnetic resonance (NMR) spectroscopy is the primary technique for elucidating the chemical structure of organic molecules including natural products. By combining various one-dimensional (1D) and two-dimensional (2D) experiments, the connectivity between atoms is established and a complete "picture" of the molecule is thereby revealed.
