N-Acetyldopamine dimer-2 (compound 2) is a N-acetyldopamine dimer that can be isolated from the yellow powder form Periostracum Cicadae with antioxidant and anti-inflammatory activities. N-Acetyldopamine dimer-2 inhibits oxidized low-density lipoprotein (LDL) oxidation, ROS generation, NO production, and NF-κB activity.

Autocamtide-2 is a highly selective peptide substrate for calcium/calmodulin-dependent protein kinase II (CaMKII), which belongs to the CAMK Ser/Thr protein kinase family.
