Webb12 apr. 2024 · 1 Introduction. M. tuberculosis is a bacteria of pathogenic (Acid-fast, Gram-positive) species from the Mycobacteriaceae family that is known to be a causative agent of tuberculosis (Van der Zanden et al., 2002).It is evident from global tuberculosis report (2024) of World Health Organization (WHO) that tuberculosis (TB) is the major source … Webb1 nov. 2014 · New triclosan (TRC) analogues were evaluated for their activity against the enoyl–acyl carrier protein reductase InhA in Mycobacterium tuberculosis (Mtb). TRC is a well‐known inhibitor of InhA, and specific modifications to its positions 5 and 4′ afforded 27 derivatives; of these compounds, seven derivatives showed improved potency over that …

Find diseases associated with this biological … WebbAmong the several anti-TB drugs, the first-line anti-TB prodrug isoniazid (INH) has the most potent bactericidal activity. After INH activation by the catalase-peroxidase (KatG) enzyme, the isonicotinic acyl–NADH (INADH) complex is created, which interacts with the enoyl-acyl carrier protein reductase (InhA) active site inhibiting the MT activity.
WebbMDR-TB isolates also had variable inhA mutations. Point mutation of inhA promoter region, such as -15 (C →T) was frequently found. Substitution of amino acid (Lsy8Asn) due to p oint mutation (AAA →AAC) of inhA ORF was found in 1 isolate. WebbTuberculosis (TB), an infectious disease caused by Mycobacterium tuberculosis, is among the top 10 leading causes of death worldwide. The treatment course for TB is challenging; it requires antibiotic administration for at least 6 months, and bacterial drug resistance makes treatment even more difficult. Understanding the mechanisms of …
WebbThe c-15t mutation in the inhA promoter region increases inhA mRNA levels by 20-fold resulting in higher InhA protein levels and an 8-fold MIC increase in M. tuberculosis . This mutation is found in about one third of the INH-resistant clinical isolates but more often in XDR TB cases than MDR or INH-monoresistant TB cases, suggesting that the c-15t …
Webb22 mars 2016 · To inhibit InhA, isoniazid must be activated by the catalase-peroxidase KatG. Isoniazid resistance is linked primarily to mutations in the katG gene. Discovery of InhA inhibitors that do not require KatG activation is crucial to combat MDR TB. Multiple discovery efforts have been made against InhA in recent years. telefoonnummer 049Webb9 okt. 2013 · InhA is a well validated Mycobacterium tuberculosis (Mtb) target as evidenced by the clinical success of isoniazid.
