3-(alphaR)-alpha-((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl) -3-hydroxybenzyl)-N-alkyl-N-arylbenzamides: Potent, non-peptidic agonists of both the mu and delta opioid receptors
Opioid analgesics with both mu and delta opioid receptor activation represent a new approach to the treatment of severe pain with an improved safety profile. Compounds with this profile may exhibit strong analgesic properties due to mu agonism, with a reduced side effect profile resulting from delta agonism. Replacing the p-diethylamide of the known potent delta opioid receptor selective agonist BW373U86 with a m-diethylamide resulted in a compound with agonist activity at both the mu and delta opioid receptors. Modifying the amide to an N-methyl-N-phenylamide increased agonist potency at both receptors. A series of 3-(alphaR)-alpha((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl) -3-hydroxybenzyl)-N-alkyl-N-arylbenzamides have been made to explore the structure-activity relationship (SAR) around the N-methyl-N-phenylamide. Several potent agonists of both the mu and delta opioid receptors have been identified, including (+)-3-((alphaR)-alpha ((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl)-3- hydroxybenzyl)-N-(4-flourophenyl)-N-methylbenzamide (23), which has EC50 values of 0.67 and 1.1 nM at the mu (guinea pig ileum assay) and delta (mouse vas deferens assay) opioid receptors, respectively.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: Isoxazoles, you can also check out more blogs about33282-15-4
