Thirteen new hydroxyethylamines have been synthesized from reactions of (2S,3S)Boc-phenylalanine epoxide, piperonylamine and arenesulfonyl chlorides in good yields. These compounds were evaluated as antibacterial agents against Mycobacterium tuberculosis H37Rv using the Alamar Blue susceptibility test and their activity expressed as the minimum inhibitory concentration (MIC) in μM. Two amino alcohols displayed significant activity when compared with first line drug ethambutol (EMB). Therefore this class of compounds could be a good starting point to develop new lead compounds in the treatment of tuberculosis.

Encapsulin nanocompartments loaded with dedicated cargo proteins via unique targeting peptides, play a key role in stress resistance, iron storage and natural product biosynthesis. Mmp1 and cysteine desulfurase (Enc-CD) have been identified as the most abundant representatives of family 2 encapsulin systems. However, the molecular assembly, catalytic mechanism, and physiological functions of the Mmp1 encapsulin system have not been studied in detail.

Article Synopsis
- Mycobacterium tuberculosis is a leading cause of global mortality, and to combat it effectively, improvements in diagnostics, drug regimens, and vaccinations are essential.
- The study investigates Furamidine, a compound that may enhance autophagy—a defense mechanism against pathogens—by evaluating its effects on tuberculosis bacteria within human cells.
- Findings demonstrate that Furamidine reduces mycobacterial growth and induces autophagy by affecting intracellular calcium levels and activating specific proteins, suggesting it could be a promising approach to improve TB treatment.
Design, Synthesis, and Anti-Mycobacterial Evaluation of Triclosan-Isoniazid Hybrids.

A series of Triclosan-based hybrids and their Schiff base derivatives with isoniazid were designed through in silico modeling and synthesized using copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction. These compounds were then evaluated against both Mycobacterium tuberculosis (Mtb) and Mycobacterium abscessus (Mab). However, none of the synthesized hybrids exhibited significant growth inhibition, with minimum inhibitory concentration (MIC) values consistently exceeding 100 µg/mL.

Tuberculosis (TB) continues to be a primary worldwide health concern due to relatively ineffective treatments. The prolonged duration of conventional antibiotic therapy warrants innovative approaches to shorten treatment courses. In response to challenges, the study explores potential of Ajoene, a naturally occurring garlic extract-derived compound, for potential TB treatment.
