Trypanothione
WebTrypanothione-disulfide reductase. In enzymology, a trypanothione-disulfide reductase ( EC 1.8.1.12) is an enzyme that catalyzes the chemical reaction. Thus, the two substrates of this enzyme are trypanothione and NADP +, whereas its 3 products are trypanothione disulfide, NADPH, and H + . This enzyme belongs to the family of oxidoreductases ... WebThe lack of therapeutic alternatives for the treatment of Chagas disease, a neglected disease, drives the discovery of new drugs with trypanocidal activity. Consequently, we conducted in vitro studies using UBMC-4, a potential Trypanosoma cruzi AKT-like pleckstrin homology (PH) domain inhibitory compound found using bioinformatics tools. The half …
