Keeping in view the drawbacks associated with research on anti-TB drugs based on plant extracts and the non-availability of fluorinated natural products with antitubercular activity has prompted us to make an effort towards the synthesis and characterization of a novel series of fifteen substituted fluorobenzimidazoles. The newly synthesized compounds were characterized by I.R, 1H-NMR, 13C-NMR,...

Due to the increasing emergence of drug resistant Tuberculosis (TB), particularly multidrug resistant TB (MDR-TB), extensive-drug resistant TB (XDR-TB) and also the development of resistance in the micro-organisms against available drugs there is a need to develop new, potent, fast-acting antibacterial and antitubercular drugs with low toxicity. With this aim different extracts of Phaseolus vul...

A series of triclosan mimic diphenyl ether derivatives have been synthesized and evaluated for their in vitro antitubercular activity against Mycobacterium tuberculosis H37Rv. The binding mode of the compounds at the active site of enoyl-acyl carrier protein reductase of M. tuberculosis has been explored. Among them, compound 10b was found to possess antitubercular activity (minimum inhibitory ...

Quaternized chlorpromazine, triflupromazine, and promethazine derivatives were synthesized and examined as antitubercular agents against both actively growing and non-replicating Mycobacterium tuberculosis H37Rv. Impressively, several compounds inhibited non-replicating M. tuberculosis at concentrations equal to or double their MICs against the actively growing strain. All active compounds were...

OBJECTIVES A novel and simple method to synthesize antitubercular-protein conjugate by solid phase synthesis was developed employing a carboxypolystyrene resin. The aim was to covalently bind a drug with antitubercular activity, isoniazid, to a biomacromolecule, gelatin, widely used in the pharmaceutical, cosmetic and food industry. METHODS Calorimetric and (1) H NMR analyses were performed t...

reaction of 2-hydrazinocarbonyl-3-chloro-5-phenoxy-benzo[b] thiophene with different substituted phenyl isothiocyanate gave n-substituted arylthiosemi-carbazide derivatives (1a-h). 1,3,4-thiadiazole derivatives (2a-h) were prepared by the cyclization of arylthiosemicarbazides (1a-h) with concentrated sulphuric acid. all the compounds were screened for their antitubercular activity against mycob...

Recently, one third of the world’s population is infected with Mycobacterium tuberculosis and 8 million new and relapse cases of tuberculosis are reported every year. The emergence of new cases, the increased incidence of multidrug resistant strains of M. tuberculosis, and the adverse effects of first and second-line antituberculosis drugs have led to renewed research interest in natural produc...

Pursuing our search program for new antitubercular drugs we decided to explore the potentiality of pyrrole moiety by molecular modeling and synthesizing novel pyrrole Schiff bases analogues of phthivazid. Enoyl-acyl carrier protein reductase catalyzes the last rate-limiting step in the elongation cycle of the fatty-acid biosynthesis pathway and has been validated as a potential antitubercular d...
