A series of Val-Leu based peptidic aldehydes containing either a furan or thiophene at the Nterminus was prepared and assayed against ovine m-calpain. In general, potency is favoured by a 2- substituted (rather than 3-substituted) heterocycle, a thiophene rather than a furan, and a shorter chain length at the N-terminus. Molecular docking experiments provide some rationale for these observations.

Keywords: Calpain inhibitors, peptidic aldehydes, synthesis, heterocycles
