Intramacrophage potential of a tetrahydropyridine: A promising compound in combating Mycobacterium tuberculosis.

Due to several obstacles in treating tuberculosis (TB), the search for new therapeutic alternatives remains a global priority. The nitrogenous heterocyclic compounds are promising in searching for new anti-Mycobacterium tuberculosis molecules, and our previous results highlight the potential of tetrahydropyridines. After exploring the antimycobacterial potential and putative mechanism of action of a tetrahydropyridine derivative (NUNL02), we seek to measure the oxidative stress caused by NUNL02 inside the extracellular replicating M.

2,2,2-trifluoro-1-(1,4,5,6-tetrahydropyridin-3-yl)ethanone derivative as efflux pump inhibitor in Mycobacterium tuberculosis.

Although the administration of combined therapy is efficient to tuberculosis (TB) treatment caused by susceptible Mycobacterium tuberculosis strains, to overcome the multidrug resistance is still a challenge. Some studies have reported evidence about tetrahydropyridines as a putative efflux pump inhibitor, including in mycobacteria, being a promising strategy against M. tuberculosis.

Synthesis of -Pyrrolyl(furanyl)-Substituted Piperazines, 1,4-Dizepanes, and 1,4-Diazocanes.

The synthetic potential of 5-bromo-1,1,1-trifluoro-4-methoxypent-3-en-2-one toward the catalyst-free synthesis of -pyrrolyl(furanyl)-piperazines, 1,4-diazepanes, and 1,4-diazocanes through a telescoped protocol is reported. This three-component one-pot method provided 23 examples with high chemo- and regioselectivity at yields up to 96%.
