Tuberculosis (TB) is leading cause of death worldwide from infectious diseases and its inadequate treatment has led to emergence of resistant strains. The emergence of these strains renders the search for new drugs for the treatment of TB. The aim of this study was the evaluation of the anti-TB activity of the extract from fungus Gliocladium sp. MR41, and bioassay-guided fractionation and ident...

Background and purpose: Quinoxaline derivatives are standing interest of people who work on anti-cancer drugs. There are many reports about using these agents as DNA cleaving, transglutaminase 2 inhibitor, topoisomerase II inhibitor and tumor antibiotic. Other drugs used in treatment of tuberculosis such as isoniazid, pyrazinamide and rifampin have similar structures to quinoxaline and quinoxal...

Three antituberculosis medications are investigated in this work consist of rifampicin, isoniazid and pyrazinamide. The ultra violet (UV) spectra of these compounds are overlapped, thus use of suitable chemometric methods are helpful for simultaneous spectrophotometric determination of them. A generalized version of net analyte signal standard addition method (GNASSAM) was used for determinatio...

Cycloserine (Seromycin) has been reported to have definite antituberculosis activity in human infection (6, 7, 8, 11, 12), but no effect in the experimental tuberculosis of mice (5, 13). In experimental tuberculosis of guinea-pigs, the antibiotic was also found inactive by two groups of investigators (9, 13), although later some histological improvement was reported by one of these groups (10)....

Oxazolidinones represent a new class of antituberculosis drugs that exert their function by inhibiting protein synthesis. Here, we compared the activities of three oxazolidinones, linezolid, PNU-100480, and AZD5847, against latent tuberculosis using a simple model employing the streptomycin-starved Mycobacterium tuberculosis strain 18b. The in vitro drug susceptibility results showed that the t...

Objective. Tuberculosis is a serious problem of public health. The increase on the number of clinical cases of tuberculosis infected with multidrug resistant (MDR) M. tuberculosis calls for the development of novel therapy. Design. We investigated the effect of mefloquine and two enantiomers, (+)erythro-mefloquine and (+)threo-mefloquine against M. tuberculosis strains in the environment resemb...

A BioFocus DPI SoftFocus library of ∼35 000 compounds was screened against Mycobacterium tuberculosis (Mtb) in order to identify novel hits with antitubercular activity. The hits were evaluated in biology triage assays to exclude compounds suggested to function via frequently encountered promiscuous mechanisms of action including inhibition of the QcrB subunit of the cytochrome bc1 complex, dis...
