Mycobacterium tuberculosis Beijing in the State of Nuevo Leon, Mexico.

Tuberculosis remains a serious threat to human health as an infectious disease in Mexico. Data about the genotypes of circulating Mycobacterium tuberculosis isolates (MTB) in the State of Nuevo Leon, Mexico are scarce. We aimed to determine the genotypes of circulating MTB belonging to the Beijing lineage recovered from patients in the State of Nuevo Leon, Mexico.

Synthesis, antimycobacterial and cytotoxic activity of α,β-unsaturated amides and 2,4-disubstituted oxazoline derivatives.

The synthesis of six α,β,-unsaturated amides and six 2,4-disubstituted oxazolines derivatives and their evaluation against two Mycobacterium tuberculosis strains (sensitive H37Rv and a resistant clinical isolate) is reported. 2,4-Disubstituted oxazolines (S)-3b,d,e were the most active in the sensitive strain with a MIC of 14.2, 13.
