dc.description.abstract | A series of organoselenium dihalides (organoselenanes) was synthesized from organoselenides using a chemoenzymatic approach. The organoselenanes have variations in their stereochemistry and in the halogen atom bonded to the selenium atom. Because of the unique selenium-thiol chemistry displayed by several organoselenium compounds, the organoselenanes were evaluated as new potential inhibitors of cysteine proteases (cathepsins S and V). By the analysis of the second-order rate constants of the inhibition of cathepsin S and V, it was possible to conclude that organoselenanes inhibited the cathepsin S faster than cathepsin V. It was observed higher inhibitory potencies for the dibromo organoselenanes derivatives than the dichloro analogues. In addition, the present data suggest the use of hypervalent selenium compounds as novel motifs for cysteine proteases inhibitors. | en |

Estas organosselenanas apresentam variações na estereoquímica e no halogênio ligado ao átomo de selênio. Devido à reação característica envolvendo compostos de selênio e tióis, estas organosselenanas foram avaliadas como inibidores de cisteíno proteases (catepsinas V e S). As constantes de inibição de segunda-ordem mostraram que a catepsina S é inibida mais rapidamente do que a catepsina V. Pode-se observar que as organosselenanas dibromadas são inibidores mais potentes do que as dicloradas. Desta forma, os resultados obtidos mostram que compostos hipervalentes de selênio podem ser aplicados como inibidores de cisteíno proteases. | pt |
