GR89,696: a potent kappa-opioid agonist with subtype selectivity in rhesus monkeys.[Pubmed:11504802]
J Pharmacol Exp Ther. 2001 Sep;298(3):1049-59.
GR89,696 is a synthetic kappa-opioid receptor agonist, recently reported to have an agonist profile consistent with selectivity at the proposed "kappa(2)" subtype. The present studies evaluated the effects of GR89,696 in vitro (i.e., in radioligand binding and [(35)S]guanosine-5'-O-(3-thio)triphosphate assays) and in vivo in rhesus monkeys, in assays used to study kappa-opioid agonists (i.e., thermal antinociception, sedation and muscle relaxation, diuresis, and increases in serum prolactin levels, as well as ethylketocyclazocine and U69,593 discrimination). Furthermore, the sensitivity of GR89,696 to naltrexone and nor-binaltorphimine (nor-BNI) antagonism was compared with that of U50,488 and U69,593, ligands selective for the proposed "kappa(1)" subtype. Overall, GR89,696 displayed the profile of a highly potent kappa-opioid agonist, following parenteral administration in rhesus monkeys. GR89,696 was less sensitive than U50,488 and U69,593 to naltrexone or nor-BNI antagonism, consistent with an action through the proposed kappa(2) receptor subtype.
A potent new class of kappa-receptor agonist: 4-substituted 1-(arylacetyl)-2-[(dialkylamino)methyl]piperazines.[Pubmed:8393489]
J Med Chem. 1993 Jul 23;36(15):2075-83.
The synthesis of 4-substituted 1-(arylacetyl)-2-[(alkylamino)methyl]piperazines (10-22, 26, 27, and 30-33) and their activities as kappa-opioid receptor agonists are described. This includes a range of 4-acyl and 4-carboalkoxy derivatives with the latter series showing the greatest kappa-agonist activity. In particular, methyl 4-[(3,4-dichlorophenyl)acetyl]-3-[(1-pyrrolidinyl) methyl]-1-piperazinecarboxylate (18) displays exceptional potency and selectivity. It showed the following activities in functional in vitro assays: rabbit vas deferens (kappa-specific tissue) IC50 = 0.041 nM, rat vas deferens (mu-specific tissue) IC50 > 10,000 nM, and hamster vas deferens (delta-specific tissue) IC50 > 10,000 nM. Compound 18 is also a highly potent antinociceptive agent, as determined in the mouse acetylcholine-induced abdominal constriction test: ED50 = 0.000 52 mg/kg, sc. The activity of 18 resides solely in its 3(R)-enantiomer. The kappa-agonist activity in both the 4-acyl and the 4-carbamate series is sensitive to the size of the 4-substituent. In addition, it would appear that an appreciable negative electrostatic potential in this region of the molecule is an important requirement for optimal potency.
Neuroprotective actions of GR89696, a highly potent and selective kappa-opioid receptor agonist.[Pubmed:1657267]
Br J Pharmacol. 1991 Jul;103(3):1819-23.
1. The effect of a novel, highly potent and selective kappa-opioid receptor agonist, GR89696, has been evaluated in two animal models of cerebral ischaemia: transient bilateral carotid artery occlusion in the Mongolian gerbil and permanent, unilateral middle cerebral artery occlusion in the mouse. 2. In the Mongolian gerbil model, administration of GR89696 (3 to 30 micrograms kg-1, s.c.), immediately before and at 4 h after insult, produced a dose-dependent reduction in the hippocampal CA1 neuronal cell loss resulting from a 7-min bilateral carotid occlusion. Similar effects were obtained with two other kappa-agonists, GR86014 (1 mgkg-1, s.c.) and GR91272 (1 mgkg-1, s.c.). The neuroprotective effect of GR89696 was completely blocked by prior administration of the opioid receptor antagonist, naltrexone, at 10 mgkg-1, s.c. Repeated post-treatment with GR89696 (100 micrograms kg-1, s.c.) or GR44821 (10 mgkg-1, s.c.) was also effective in protecting completely the hippocampal CA1 neurones from ischaemia-induced neurodegeneration. 3. In the permanent, unilateral middle cerebral artery occlusion model in the mouse, repeated administration of GR89696 at 300 micrograms kg-1, s.c. produced a 50% reduction in cerebrocortical infarct volume. In these experiments GR89696 was dosed 5 min, 4, 8, 12, 16, 20 and 24 h after occlusion on the first day and then three times daily for the next three days. GR89696 (300 micrograms kg-1) also produced a significant 35% reduction in infarct volume in this model when the initiation of dosing was delayed for 6 h after the insult. 4. The results indicate that the potent kappa-opioid receptor agonist, GR89696, is neuroprotective in both global and focal cerebral ischaemia models and suggest that, with this class of compound, there may be a considerable time window for pharmacological intervention.
