Synthesis of caged peptides using caged lysine: application to the synthesis of caged AIP, a highly specific inhibitor of calmodulin-dependent protein kinase II.

摘要

N(alpha)-Fmoc-N(epsilon)-(2-nitrobenzyloxycarbonyl)-lysine has been prepared and used in the solid-phase synthesis of caged peptides. The synthesized caged AIP (cagedKcagedKALRRQEAVDAL) showed characteristics required for caged peptides including a significantly reduced inhibitory activity to calmodulin-dependent protein kinase II and instantaneous recovery of the activity with photo-irradiation.
