We characterized TRK-130 (N-[(5R,6R,14S)-17-(cyclopropylmethyl)-4,5-epoxy-3,14-dihydroxymorphinan-6-yl]phthalimide; naltalimide), an opioid ligand, to clarify the therapeutic potential for overactive bladder (OAB). In radioligand-binding assays with cells expressing human µ-opioid receptors (MORs), δ-opioid receptors (DORs), or κ-opioid receptors (KORs), TRK-130 showed high selectivity for MORs (Ki for MORs, DORs, and KORs = 0.268, 121, and 8.97 nM, respectively). In a functional assay (cAMP…

It is suggested that TRK-130 enhances the bladder storage function by modulating the afferent limb of the micturition reflex through µ-opioid receptors in the spinal cord with a different fashion from antimuscarinics and conventional opioids for overactive bladder.

A good safety profile for DPI-221 administered orally, with potent efficacy in modifying bladder activity is indicated, and the most crucial safety aspect of δ agonist administration is the incidence of seizure-like convulsions in rodents.

The results suggest that in conscious rats, D1 receptors tonically inhibit the micturition reflex and that D2 receptors are involved in facilitation of the mitzurition Reflex, which may be speculated that detrusor hyperreflexia associated with Parkinson's disease results from activation failure of D 1 receptors and that administration of D2 receptor agonists might worsen the condition.

The results suggest that the intrinsic efficacy of agonists at G-protein-coupled receptors is determined primarily by the ability of the agonist-occupied receptor to promote high-affinity GTP binding to the G- protein and to catalytically activate a maximal number G-proteins.
