  Mycobacterium tuberculosis lysine-ɛ-aminotransferase a potential target in dormancy: Benzothiazole based inhibitors

  摘要：

  MTB lysine-epsilon-aminotransferase (LAT) was found to play a crucial role in persistence and antibiotic tolerance. LAT serves as a potential target in the management of latent tuberculosis. In present work we attempted to derivatize the benzothiazole lead identified through high throughput virtual screening of Birla Institute of Technology and Science in house database. For Structure activity relationship purpose 22 derivatives were synthesized and characterized. Among synthesized compounds, eight compounds were found to be more efficacious in terms of LAT inhibition when compared to lead compound (IC50 10.38 +/- 1.21 mu M). Compound 22 exhibits bactericidal action against nutrient starved Mycobacterium tuberculosis (MTB). It also exhibits significant activity in nutrient starvation model (2.9 log folds) and biofilm model (2.3 log folds). 2017 Elsevier Ltd. All rights reserved.

  A series of (E)-2-(benzo[d]thiazol-2-yl)-3-arylacrylonitriles was synthesized by microwave assisted Knoevenagel condensation under solvent-free conditions from the corresponding 2-(benzo[d]thiazol-2-yl) acetonitrile and aromatic aldehydes with electrondonating/electron-withdrawing groups. The reaction times were considerably short and the products obtained in moderate yields (50 to 75%) and good purity. The configuration of the acrylonitrile double bond could not be established by regular NMR methods. However, theoretical studies suggest that the E isomer is more stable than Z, which is in good agreement with some experimental evidences.
