In our previous study, we reported a series of 1-hydroxy-2-phenyl-1H-imidazole-5-carboxylic acid derivatives that presented excellent in vitro xanthine oxidase inhibitory potency. As a continuation study, a series of 1-hydroxy-2-phenyl-1H-imidazole derivatives containing a pyridine moiety (4a-g and 5a-g) at the 4-position was designed and synthesized. Evaluation of in vitro xanthine oxidase inhibition demonstrated that the 4a-g series was more potent than the 5a-g series. Compound 4f was the most promising derivative in the series with an IC50 value of 0.64 μM. A Lineweaver-Burk plot revealed that compound 4f acted as a mixed-type xanthine oxidase inhibitor. An iso-pentyloxy group at the 4′-position improved the inhibitory potency. More interestingly, structure-activity relationship analysis indicated that the pyridine para-N atom played a crucial role in the inhibition. Molecular modeling provided a reasonable explanation for the structure-activity relationships observed in this study. In addition, a three dimensional quantitative structure-activity relationships model which possessed reasonable statistics (q2 = 0.885 and r2 = 0.993) was conducted to further understand the structural basis of these compounds as xanthine oxidase inhibitors. These compounds, especially compound 4f, have good potential for further investigations.
PERIPHERALLY RESTRICTED FAAH INHIBITORS

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.
