Ac-VEID-CHO (trifluoroacetate salt)

Ac-VEID-CHO is an inhibitor of caspase-6 (IC50 = 16.2 nM). It is selective for caspase-6 over caspase-7 (IC50 = 162.1 nM) but can also inhibit caspase-3 (IC50 = 13.6 nM). Ac-VEID-CHO (100 µM) inhibits ricin-induced caspase-6-, but not caspase-3-, like activity in U937 cells. It also inhibits caspase-6-like activity in Norway spruce cell extracts when used at a concentration of 2 µM, as well as in staurosporine-treated SKNAS neuroblastoma cells with an IC50 value of 0.49 µM.Formal Name: (4S,7S,10S,13S)-10-((S)-sec-butyl)-7-(2-carboxyethyl)-13-formyl-4-isopropyl-2,5,8,11-tetraoxo-3,6,9,12-tetraazapentadecan-15-oic acid, trifluoroacetate salt.
