Identification of potent phenyl imidazoles as opioid receptor agonists
摘要:
Using previously reported opioid receptor (OR) agonist analogs 4a-c as starting points, the structure-activity relationship (SAR) for their related series has been further refined. This SAR Study has led to the identification of 2,6-di-Me-Tyr (DMT) analogs 4h and 4j as the most potent OR agonist within the series. in addition, it was discovered that 4-(aminocarbonyl)-2,6-dimethyl-Phe is a reasonable bioisostere surrogate for the DMT moiety, as supported by the OR activities Of Compounds 4x and 4y.
