Opioid Receptor Phosphorylation Assays

Opioid receptors are activated by a variety of endogenous peptides including enkephalins, β-endorphin, dynorphins or nociceptin/orphanin FQ (N/OFQ) that mediate primarily inhibitory functions in the central and peripheral nervous system. The opioid receptor family consists of four members designated μ-opioid receptor (mu-opioid receptor, MOP), δ-opioid receptor (delta-opioid receptor, DOP), κ-opioid receptor (kappa-opioid receptor, KOP), N/OFQ receptor (NOP). All four opioid receptors can mediate analgesic effects, which are accompanied by receptor-specific side effects. MOP is the pharmacological target for many clinically-used analgesics including morphine, oxycodone, fentanyl and methadone. The utility of µ-analgesics is limited by sever side effects such as respiratory depression, constipation and addiction. Specific side-effects induced by DOP, KOP and NOP include seizures, dysphoria and sedation, respectively. One strategy for the development of safer analgesics with fewer side effects is the development of drugs that target multiple opioid receptors. An alternative approach is the development of biased opioid analgesics.
