Eight new phenylisoxazole isoniazid derivatives, 3-(2′-fluorophenyl)isoxazole-5-carbaldehyde isonicotinylhydrazone (1), 3-(2′-methoxyphenyl)isoxazole-5-carbaldehyde (2), 3-(2′-chlorophenyl)isoxazole-5-carbaldehyde (3), 3-(3′-clorophenyl)isoxazole-5-carbaldehyde (4), 3-(4′-bromophenyl)isoxazole-5-carbaldehyde (5), 5-(4′-methoxiphenyl)isoxazole-3-carbaldehyde (6), 5-(4′-methylphenyl)isoxazole-3-c...

Heterocyclic compounds containing a pyrimidine nucleus are of special interests due to their applications in medicinal chemistry as they are the basic skeleton of several bioactive compounds such as antifungal, antibacterial, antitumor and antitubercular. As a part of our research in the synthesis of pyrimidine derivatives containing biological activities, some new tetrahydropyrimidine derivati...

A survey of the pertinent literature reveals that aryl imidazoles have been found to possess a wide spectrum of biological activity such as antibacterial [1], antirheumatoid arthritis [2], antitubercular [3], antiviral [4], anti-inflammatory [5] and anticancer activities [6-8]. Specifically, it has been revealed from the literature that imidazoles fused with indole nucleus possess various biolo...

Tuberculosis was declared as a global pandemic and panic because the causative Mycobacterium tuberculosis can kill an incredible number of individuals which formulate a major obstacle to social and economic development of the country. Most of the developing countries are affected by tuberculosis. Antitubercular therapy involves the use of Directly Observed Therapy Short (DOTS) course for 6-9 mo...

Pyrimidines represent an important class of heterocycles containing two nitrogen atoms at position 1 and 3 the six membered ring show wide range biological activities. Numerous methods for synthesis pyrimidine their diverse reactions offer enormous scope in field medicinal chemistry. Pyrimidine possesses spectrum activities including antitubercular, antibacterial, antifungal, antiviral, anti-in...

New analogues of antitubercular drug PA-824 were synthesized, featuring alternative side chain ether linkers of varying size and flexibility, seeking drug candidates with enhanced metabolic stability and high efficacy. Both α-methyl substitution and removal of the benzylic methylene were broadly tolerated in vitro, with a biaryl example of the latter class exhibiting an 8-fold better efficacy t...
