Ring closing metathesis and cross metathesis approaches to a new macrocyclic peptidomimetic aldehyde 2 have been developed, with the former route being the most convenient. Aldehyde 2 is a potent inhibitor of calpain II (IC50 of 45 nM) with comparable activity to the benchmark acyclic inhibitor SJA6017 4. Both compounds contain an N-terminal 4-fluorophenylsulfonyl group. The P2 Ile analogue of 2 (16) is significantly less active (IC50 of 2000 nM) which reflects an unusually subtle importance of the P2 residue for active site binding.
