Interação de compostos organossulfurados derivados do alho com o citocromo-c: um estudo eletroquímico
Organosulfur compounds present in garlic and onion have been evaluated as inhibitors of chemical carcinogenesis. Among them diallylsulfide was mainly investigated and studies demonstrated its metabolization to the corresponding sulfoxide and sulfone. In this work, we report the investigation of the interaction between the diallylsulfide and its oxidized derivatives, through cyclic voltammetry, with horse heart cytocrome-c (on a modified electrode with 4-mercaptopyridine). Our results suggest that there is a reversible interaction between cytocrome-c and diallylsulfide and diallylsulfone and an irreversible interaction with the diallylsulfoxide.
