Exploring the Binding Affinity of Novel Syringic Acid Analogues and Critical Determinants of Selectivity as Potent Proteasome Inhibitors.

Syringic acid, a known plant phenolic compound and its analogues are known to possess high proteasome inhibitory activity. In the current work, we describe synthesis, characterization, DFT, docking of syringic acid (SA) and analogues (SAA1 and SAA2) and biological effects were studied. Syringic acid and its analogues were docked for the first time with the crystal structures of β5 proteasome of diverse eukaryotic organisms.

Comprehensive structural and functional characterization of Mycobacterium tuberculosis UDP-NAG enolpyruvyl transferase (Mtb-MurA) and prediction of its accurate binding affinities with inhibitors.

Tuberculosis (TB) remains the most frequent and important infectious disease causing morbidity and death in the world. One third of the world's population is infected with Mycobacterium tuberculosis (Mtb), the etiologic agent of TB. The bacterial enzyme MurA catalyzes the transfer of enolpyruvate from phosphoenolpyruvate (PEP) to uridine diphospho-N-acetylglucosamine (UNAG), which is the first committed step of bacterial cell wall biosynthesis.
