Polyheterocycles are one of the most desired synthetic targets due to their numerous and valuable applications in various fields. We report the design and the parallel synthesis of novel linear oligocyclic guanidine peptidomimetics from predesigned reduced polyamides. A screening of these compounds identified active Mycobacterium tuberculosis DNA gyrase inhibitors which do not inhibit human DNA topoisomerase IIα and topoisomerase I.

Background: Wastewater-based epidemiology (WBE) is already being adopted for the surveillance of health conditions of communities and shows great potential for the monitoring of infectious pathogens of public health importance. There is however paucity of robust data to support extensive WBE in Nigeria. This study evaluated the prevalence of clinically relevant infectious pathogens and provided antimicrobial resistance profiles of bacteria pathogens in wastewater canals in Lagos State at a single point in time.

Mycobacterium species cause several vital human diseases, including tuberculosis and non-tuberculous mycobacterial infections which are treated with different drug regimens Therefore, accurate and rapid diagnosis is essential for effective treatment and controlling the spread of these pathogens. This study aims to develop the isothermal method combining RPA and CRISPR-Cas12a techniques, named as MyTRACK, to detect and differentiate major clinical mycobacteria at the species level. The assay has no cross-reactivity with limit of detection of 1 to 100 copies/reaction for various targeted mycobacteria.

Background: Worldwide, tuberculosis (TB) is among the most common causes of death. To our knowledge, there has been no study showing the prevalence of EPTB in Khuzestan province. Therefore, the objective of this research was to investigate the prevalence of EPTB in patients with or without pulmonary TB in different cities of Khuzestan province from 2002 to 2023.

This report explores the potential of novel 6-aryloxy-2-aminopyrimidine-benzonitrile scaffolds as promising anti-infective agents in the face of the increasing threat of infectious diseases. Starting from 2-amino-4,6-dichloropyrimidine, a series of 24 compounds inspired from the antiviral drugs dapivirine, etravirine, and rilpivirine were designed and synthesized via a two-step reaction sequence in good yields. Biological testing of synthetic analogs revealed potent inhibition against both viral and tuberculosis targets.
