7-Methoxy-8-decynyl-benzolactam-V8 4 is synthesized using a catalytic asymmetric alkylation reaction as a key step. This compound shows potent activity to three PKC isozymes tested (Ki= 45.6, 91.1, and 121.3 nM to PKCα, δ, and ε, respectively), indicating that introduction of a suitable substituent at the 7-position of 8-decynyl-benzolactam-V8 only slightly reduces the PKC binding affinity.
