INTRODUCTION Increasing numbers of children with drug-resistant tuberculosis are accessing second-line antituberculosis drugs; these are more toxic than first-line drugs. Little is known about the safety of new antituberculosis drugs in children. Knowledge of adverse effects, and how to assess and manage these, is important to ensure good adherence and treatment outcomes. AREAS COVERED A Pubm...

INTRODUCTION Combination antituberculosis drug therapy remains the mainstay of treating tuberculosis. Unfortunately, antituberculosis drugs produce side effects including (toxic) impaired visual function, which may be irreversible. We report a case of antituberculosis-drug-induced impaired visual function that was reversed following early detection and attention. CASE PRESENTATION A 37-year-o...

Fluoroquinolones are known widely used synthetic antibacterial agents. Generally, there were some obstacles associated with their therapeutic use. Moreover, many research studies all over the world proved variable biological effects of fluoroquinolones such as antituberculosis, anticancer, or even antiviral activities. The current review is focused on modifications that occurred in fluoroquinol...

Background The present study was undertaken to investigate the hepatoprotective effect of Aloe vera against side effect of antituberculosis drug. Material and methods Twenty-five rats will be divided into five groups, namely the control group (without any treatment), the group of rats treated with anti-tuberculosis drugs, and a group of rats were treated antituberculosis drugs and got Aloe ve...

Nonreplicating and metabolically quiescent bacteria are implicated in latent tuberculosis infections and relapses following "sterilizing" chemotherapy. However, evidence linking bacterial dormancy and persistence in vivo is largely inconclusive. Here we measure the single-cell dynamics of Mycobacterium tuberculosis replication and ribosomal activity using quantitative time-lapse microscopy and ...

Pyrazinamidase activity in clinical isolates of Mycobacterium tuberculosis has been previously found to correlate with susceptibility to the antituberculosis drug pyrazinamide. The Wayne method for determining pyrazinamidase activity, a technique also utilized as an aid in identification of mycobacteria, and thin-layer chromatography method were found to be useful screening methods for suscepti...

Small-molecule inhibitors of the mycobacterial transcriptional repressor EthR have previously been shown to act as boosters of the second-line antituberculosis drug ethionamide. Fragment-based drug discovery approaches have been used in the past to make highly potent EthR inhibitors with ethionamide boosting activity both in vitro and ex vivo. Herein, we report the development of fragment-sized...

A total of seven novel benzimidazoles were synthesized by a 4-step reaction starting from 4-fluoro-3-nitrobenzoic acid under relatively mild reaction conditions. The synthesized compounds were screened for their antimycobacterial activity against M. tuberculosis H₃₇Rv (MTB-H₃₇Rv) and INH-resistant M. tuberculosis (INHR-MTB) strains using agar dilution method. Three of them displayed good activi...
