recent studies have indicated that 1, 4-dihydropyridine-3, 5-dicarboxamidederivativesshow significant anti-tubercular activity. in this research, new derivatives of 1, 4-dihydropyridine were designed and synthesized using hantzsch condensation in which dicyclohexyl and different dicyclohexylcarbamoylwere substituted at c-3 and c-5 positions of the dhp ring.in addition, 4 (5)-chloro-2-methyl-5 (...

The 2-aminothiazole series has anti-bacterial activity against the important global pathogen Mycobacterium tuberculosis. We explored the nature of the activity by designing and synthesizing a large number of analogs and testing these for activity against M. tuberculosis, as well as eukaryotic cells. We determined that the C-2 position of the thiazole can accommodate a range of lipophilic substi...

Tuberculosis is a global menace, caused by Mycobacterium tuberculosis, responsible for millions of premature deaths every year. In the era of drug-resistant tuberculosis, peptide-based therapeutics may provide alternate to small molecule based drugs. In order to create knowledgebase, AntiTbPdb (http://webs.iiitd.edu.in/raghava/antitbpdb/), experimentally validated anti-tubercular and anti-mycob...

Hepatic tuberculosis is uncommon, lack of specific clinical manifestations and imaging features, so it can easily be misdiagnosed in clinical. Herein, we discuss variety of its forms and summarize the diagnosis and treatment of hepatic tuberculosis in this paper. Five cases of hepatic tuberculosis are described. The diagnosis, treatment and outcome of the patients are discussed. Image examinati...

In an investigation into their potential ecological role(s), a group of mainly diterpene isonitriles, nine in total, isolated from the tropical marine sponge Cymbastela hooperi, and the sesquiterpene axisonitrile-3, isolated from the tropical marine sponge Acanthella kletra, were evaluated in a series of bioassays including anti-fouling, anti-algal, anti-photosynthetic, anti-bacterial (Gram +ve...

In the present investigation, a series of 3-(4-methoxyphenyl)-1-isonicotinoyl-5-(substituted phenyl)-formazans (5a-r) were synthesized by condensation of schiff base (3) and diazonium salt of various substituted aromatic amines, (3a-r). The intermediate schiff base (3) was itself synthesized by condensation of isonicotinic acid hydrazide with 4methoxybenzaldehyde (2). The structures of the comp...

Mycobacterium tuberculosis is the focus of several investigations for design of newer drugs, as tuberculosis remains a major epidemic despite the availability of several drugs and a vaccine. Mycobacteria owe many of their unique qualities to mycolic acids, which are known to be important for their growth, survival, and pathogenicity. Mycolic acid biosynthesis has therefore been the focus of a n...
