Researchers report 3 peptides isolated from a species of the fungus Penicillium found in an Australian estuary that contain naturally formed amino acids exhibiting mirror image structures rarely seen in amino acids in nature; based on the peptides’ structures, the researchers developed bilorphin and bilactorphin, analgesics that act on opioid receptors but through a different signaling pathway than traditional opioid medications, suggesting that the analgesics might pave the way toward the development of drugs for effective pain management with few adverse side effects.
