Benzothiazole (BTA) and its derivatives are the most important heterocyclic compounds, which are common and integral feature of a variety of natural products and pharmaceutical agents. BTA shows a variety of pharmacological properties, and its analogs offer a high degree of structural diversity that has proven useful for the search of new therapeutic(More)
From the reaction of 1-methylimidazole (1a), 4,5-dichloro-1H-imidazole (1b(I)) and 1-methylbenzimidazole (1c) with p-cyanobenzyl bromide (2a), non-symmetrically substituted N-heterocyclic carbene (NHC) [(3a-c)] precursors, 5,6-dimethyl-1H-benzimidazole (1d) and 4,5-diphenyl-1H-imidazole (1e) with p-cyanobenzyl bromide (2a) and benzyl bromide (2b),(More)
New lanthanide(III) complexes with 2-[2-hydroxy-3-methoxyphenyl]-3-[hydroxyl-3-methoxybenzylamino]-1,2-dihydroquin- azoline-4(3H)-one (Hmpbaq) have been synthesized and characterized by elemental analysis, conductance measurements, magnetic susceptibilities, spectroscopic (IR, NMR, UV, EPR), and thermal studies. Molar conductance studies indicate 1 : 1(More)
Tuberculosis is a contagious disease with comparatively high mortality worldwide. The statistics shows that around three million people throughout the world die annually from tuberculosis and there are around eight million new cases each year, of which developing countries showed major share. Therefore, the discovery and development of effective(More)
Tuberculosis (TB) remains a global public health problem in recent years. TB originated mainly from various strains of Mycobacterium tuberculosis, is a highly infectious and chronic disease with high infection rate since ancient times. Since the last 50 years, the same long-duration, multidrug treatment plan is being followed for the treatment of(More)
The synthesis and characterisation of lanthanide(III) and yttrium(III) nitrate complexes of benzimidazole-2-acetic acid (HBIA) are reported. The complexes have been characterised by elemental analysis, molar conductance, magnetic studies, IR, (1)H NMR, UV-visible, EPR, and TG/DTA studies. They have the stoichiometry [Ln(3)(BIA)(2)(NO(3))(7)(H(2)O)(4)] .(More)
The title compound, C11H12N6O2, a π-conjugated triazene, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. Both mol-ecules have an E conformation about the -N=N- bond and have slightly twisted overall conformations. In mol-ecule A, the imidazole ring is inclined to the benzene ring by 8.12 (4)°, while in mol-ecule B the two(More)
Macrocyclic chemistry is one of the emerging research areas in the chemical science.
