Synthetic procedure for the synthesis of naproxen-HBTA (A, 5). H2S-releasing properties of HBTA evaluated by an amperometric approach. Curve describes the increase of H2S concentration, with respect to time, following the incubation of HBTA (1 mM) in the assay buffer with (Inline graphic) or without (Inline graphic) the nucleophile L-cysteine. H2S was recorded by amperometry; the vertical bars indicate the SEM (B).
