Abstract
Thiolactomycin (TLM) is a natural product inhibitor of KasA, the ?-ketoacyl synthase A from Mycobacterium tuberculosis. To improve the affinity of TLM for KasA, a series of TLM analogs have been synthesized based on interligand NOEs between TLM and a pantetheine analog when both are bound simultaneously to the enzyme. Kinetic binding data reveal that position 3 of the thiolactone ring is a suitable position for elaboration of the TLM scaffold, and the structure-activity relationship studies provide information on the molecular features that govern time-dependent inhibition in this enzyme system. These experiments also exemplify the utility of transient one-dimensional NOE spectroscopy for obtaining interligand NOEs compared with traditional steady state two-dimensional NOESY spectroscopy.

Over the past three decades nuclear magnetic resonance spectroscopy has been developed into a mature technique for the characterization of interactions of small molecule ligands with their corresponding protein and nucleic acid receptors. In fact, a significant number of industrial and academic laboratories employ NMR for screening small...
