- 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.

- Synthesis of mesoionic 4-(para-substituted phenyl-5-2,4-dichlorophenyl)-1, 3-4-thiadiazolium-2-aminides by direct cyclization via acylation of thiosemicarbazides
-
The synthesis of ten novel mesoionic 4-[para-substituted (H, CH 3, OCH3, NO2, Cl, Br, OH, t-C4H 9, C6H5, C4H9) phenyl-5-2,4-dichlorophenyl]-1,3-4-thiadiazolium-2-aminides, as hydrochlorides, are described. The synthesis strategy utilized the corresponding para-substituted isothiocyanates as starting materials to obtain the thiosemicarbazides through reaction with phenylhydrazine (61-98%), which were then submitted to acylation with 2,4-dichloro benzoyl chloride and direct cyclization to generate the desired substituted mesoionic compounds in good yields (ca. 80%).
