Owing to the persistence of tuberculosis (TB) as well as the emergence of multidrug-resistant and extensively drug-resistant (XDR) forms of the disease, the development of new antitubercular drugs is crucial. Developing inhibitors of shikimate kinase (SK) in the shikimate pathway will provide a selective target for antitubercular agents. Many studies have used in silico technology to identify c...

OBJECTIVES Analyse a series of halogenated 3-deaza-adenosine analogues for efficacy against Mycobacterium tuberculosis H37Ra and determine if adenosine (Ado) kinase plays a role in the mechanism of action of these compounds. METHODS The MIC as determined by microdilution broth assay provided a measure of antitubercular efficacy. MIC values were measured in M. tuberculosis strains H37Ra, SRICK...

Two series of chloroisatin-3-semicarbazones and hydrazones have been designed and prepared by condensing 4-chloro and 6-chloroisatin with several substituted semicarbazides and related bioisosteric hydrazides, respectively. Investigation of in vitro antimicrobial activity of compounds has been performed by agar double dilution method against nine pathogenic bacteria and four pathogenic fungi. T...

OBJECTIVES To evaluate a novel series of quinoxaline 1,4-di-N-oxides for in vitro activity against Mycobacterium tuberculosis and for efficacy in a mouse model of tuberculosis (TB). METHODS Ketone and amide derivatives of quinoxaline 1,4-di-N-oxide were evaluated in in vitro and in vivo tests including: (i) activity against M. tuberculosis resistant to currently used antitubercular drugs incl...

In the present investigation, a series of 12 Mannich bases (QP1-12) and 5 Schiff bases (QSP1-5) of pyrazol-5(4H)-one moiety containing 3-(hydrazinyl)-2-phenylquinazolin-4(3H)-one has been synthesized and characterized by physicochemical as well as spectral means. The synthesized Mannich and Schiff bases were screened for their preliminary antimicrobial activity against Gram-positive and Gram-ne...

BACKGROUND Psoas abscess complicating tuberculous spondylitis is a rare morbidity in extrapulmonary tuberculosis. There are no established guidelines for evaluating the clinical response of psoas abscess. Although several studies have shown that positron emission tomography-computed tomography with 18 F-fluorodeoxyglucose can play a potential role in diagnosing multifocal tuberculosis and monit...
