“…Like a typical nitrofuran, NFOH can inhibit the T. cruzi trypanothione reductase, releasing the toxic superoxide anion that ultimately causes DNA damage and cell death. Moreover, NFOH is also able to inhibit 60% of cruzipain activity, whereas nitrofurazone produces only 30% inhibition (31). This new property also suppresses the metabolic pathways that involve the major T. cruzi cysteine protease.…”

“…Rational design and latentiation led to the design of NFOH, which acts as a prodrug with strong in vitro anti-T. cruzi activity, being twice as active as the parent compound, NF (8,15). NFOH is reported to be four times less mutagenic in the Ames test than its parent compound (15), and it has been postulated to have a dual mechanism of action (31). Like a typical nitrofuran, NFOH can inhibit the T. cruzi trypanothione reductase, releasing the toxic superoxide anion that ultimately causes DNA damage and cell death.…”

“…A pesquisa de inibidores da cruzaína é, atualmente, realizada com auxílio de técnicas modernas de planejamento de fármacos buscando a melhoria e a seletividade de compostos ativos contra essa enzima e selecionando com sucesso classes de compostos não-peptídicos como inibidores, entre elas semicarbazonas e tiossemicarbazonas, chalconas, isatinas, hidroximetil-cetonas, acil-hidrazidas, tiazolil-hidrazonas, vinil-sulfonas, aril-uréias, macrociclos e complexos metálicos (VITAL, ARRIBAS, TROSSINI, 2014;BLAU et al, 2013;CARVALHO et al, 2012;HERNANDES et al, 2010;TROSSINI et al, 2010;BRYANT et al, 2009;BORCHHARDT et al, 2009;CHEN et al, 2008;JAISHANKAR et al, 2008;BRAK et al, 2008;ZANATTA et al 2008;DUSCHAK, COUTO, 2007;SILES et al, 2006;AGUIRRE et al, 2006;DU et al, 2002).…”

“…(RIVERA et al, 2009;SAJID, McKERROW, 2002) Dentre as diversas classes químicas testadas contra o T. cruzi atuantes na inibição da cruzaína, as semicarbazonas, tiossemicarbazonas e N-acil-hidrazonas tem se mostrado promissoras (BLAU et al, 2013;CARVALHO et al, 2012;TROSSINI et al, 2010;RIVERA, 2009;DU et al, 2002). Baseando-se nestes estudos, Trossini e colaboradores (2010) realizaram testes de inibição da cruzaína com o nitrofural (NF) e seu análogo hidroximetil-nitrofural, os quais apresentam um grupo semicarbazona, bioisóstero da tiossemicarbazona já reportada como inibidor de cruzaína, confirmando a atividade destes compostos frente à enzima (NF com IC50 de 22,83 µM e o derivado hidroximetilado 10,55 µM).…”
