EcAMP3 is a hairpin-like peptide. EcAMP3 has antifungal and antibacterial activity. EcAMPs precursor family contains seven identical cysteine motifs: C1XXXC2(11–13)C3XXXC4.

(2E,4E,6Z)-Methyl deca-2,4,6-trienoate (Methyl (2E,4E,6Z)-decatrienoate), a small molecular compound from the bed bug Thyanta pallidovirens, is a thermally unstable sexually attractive pheromone.

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.
