    • Peripherally restricted inhibitors of fatty acid amide hydrolase (FAAH) are provided. The compounds can suppress FAAH activity and increases anandamide levels outside the central nervous system (CNS). Despite their relative inability to access brain and spinal cord, the compounds attenuate behavioral responses indicative of persistent pain in rodent models of inflammation and peripheral nerve injury, and suppresses noxious stimulus-evoked neuronal activation in spinal cord regions implicated in nociceptive processing. CBi receptor blockade prevents these effects. Accordingly, the invention also provides methods, and pharmaceutical compositions for treating conditions in which the inhibition of peripheral FAAH would be of benefit. The compounds of the invention are according to the formula (I): in which R1 is a polar group. In some embodiments, R1 is selected from the group consisting of hydroxy and the physiologically hydro lysable esters thereof. R2 and R3 are independently selected from the group consisting of hydrogen and substituted or unsubstituted hydrocarbyl; each R4 is independently selected from the group consisting of halogen and substituted or unsubstituted hydrocarbyl and n is an integer from 0 to 4; each R5 is independently selected from the group consisting of halo and substituted or unsubstituted hydrocarbyl and m is an integer from 0 to 3; and R6 is substituted or unsubstituted cyclohexyl; and the pharmaceutically acceptable salts thereof.
    • 提供脂肪酸酰胺水解酶(FAAH)的外周限制性抑制剂。 该化合物可以抑制FAAH活性,并增加中枢神经系统(CNS)外的氨基酰胺水平。 尽管它们相对不能进入脑和脊髓,但化合物减弱了指示炎症和周围神经损伤的啮齿动物模型中的持续疼痛的行为反应,并且抑制了与伤害性处理相关的脊髓区域中的有害刺激诱发的神经元激活。 CBi受体阻断防止这些影响。 因此,本发明还提供了用于治疗其中外周FAAH的抑制将是有益的病症的方法和药物组合物。 本发明的化合物根据式(I):其中R1是极性基团。 在一些实施方案中,R 1选自羟基及其生理上可水解的酯。 R2和R3独立地选自氢和取代或未取代的烃基; 每个R 4独立地选自卤素和取代或未取代的烃基,n是0至4的整数; 每个R 5独立地选自卤素和取代或未取代的烃基,m是0-3的整数; 并且R 6是取代或未取代的环己基; 及其药学上可接受的盐。
