Synthesis, characterization, and antibacterial activity of some thiazoles derived from allyl thioureas
Synthesis of thiazoles was carried out from allyl thioureas using different cyclizing agents such as hydrogen chloride gas and bromine. Synthesized compounds were characterized by IR, 1H and 13C NMR, mass spectrometry, and elemental analysis. The synthesized thiazoles were evaluated for their antibacterial activity against Gram postitive (Lactobacillus bulgaris and Streptococcus mitis) and Gram negative (Yersinia) as well as antifungal activity against Aspergillus niger fungi.
Synthesis and biological evaluation of arylthiourea derivatives with antitubercular activity
Tuberculosis (TB) is a contagious disease caused by Mycobacterium tuberculosis (M. tuberculosis), and remains one of the most life-threatening plagues for public health in the world. The emergence of drug resistant strains of TB and co-infection with HIV has further complicated TB treatment. Here, the synthesis and characterizaton of a series of compounds were described, and these were followed by evaluating for their antibacterial activity against M. tuberculosis. Several novel arylthiourea derivatives exhibited excellent activity (lowest MIC=0.09 μg/ml) against M. tuberculosis including drug resistant strains of M. tuberculosis. The results suggest that these compounds are promising candidates for new anti-TB agent development.
