Bilaid C1 (YvVf-NH2) is the semi-synthetic analogue of Bilaid C, an unusual tetrapeptide isolated from an Australian estuarine isolate of Penicillium sp. MST-MF667. Conversion of the terminal carboxylate to its corresponding amide enhanced the μ-opioid agonist potency leading to the design of more potent analogues, bilorphin and bilactorphin.
