(D-Arg2, Sar 4)-Dermorphin (1-4) is a tetrapeptide derivative of the peptide Dermorphin found in amphibian skin. (D-Arg2, Sar 4)-Dermorphin (1-4) has significant analgesic effects by binding to the μ-opioid receptor (MOR) in the body. (D-Arg2, Sar 4)-Dermorphin (1-4) can be used in the development of analgesic drugs.

Helodormin is a VIP-secretin-like peptide isolated from the venom of the Mexican monster lizard (Heloderma suspectum). Helodormin affects a variety of cellular functions by modulating intracellular signaling through activation of adenylate cyclase. Helodormin can be used to study the evolution and function of the secretin and VIP peptide families.
