Title: Structure-activity relationships of hypervalent organochalcogenanes as inhibitors of cysteine cathepsins V and S.
Authors: Piovan L, Alves MF, Juliano L, Brömme D, Cunha RL, Andrade LH.
Abstract: A new series of organotelluranes were synthesized and investigated, and the structure-activity relationships in cysteine proteases inhibition were determined. It was possible to identify the relevance of structural components linked to the reactivity of these compounds as inhibitors. For example, dibromo-organotelluranes showed to be more reactive than dichloro-organotelluranes towards cysteine cathepsins V and S. Besides, no remarkable enantio-selectivity was verified. In general the achiral organotelluranes were more reactive than the chiral congeners against cysteine cathepsins V and S. A reactivity order for organochalcogenanes and cysteine cathepsins was proposed after the comparison of the inhibitory potencies of organotelluranes with the related organoselenanes.
