  Inhibition of Oleamide Hydrolase Catalyzed Hydrolysis of the Endogenous Sleep-Inducing Lipid cis-9-Octadecenamide

  摘要：

  Oleamide (1, cis-9-octadecenamide) is a naturally occurring brain constituent that. has been shown to accumulate and disappear under conditions of sleep deprivation and sleep recovery, respectively. Synthetic 1 has been found to induce sleep in a structurally specific manner at nanomolar quantities. Hydrolysis of 1 by an enzyme (oleamide hydrolase) present in the cell membrane rapidly degrades oleamide to oleic acid (cis-9-octadecenoic acid). Such observations suggest 1 may constitute a prototypical member of a class of fatty acid primary amide biological signaling molecules in which the diversity and selectivity of function are derived from the length of the alkane chain as well as the position, stereochemistry, and degree of unsaturation. A series of inhibitors of oleamide hydrolase were designed and prepared which were expected to derive their properties through interactions with the putative active site cysteine residue within oleamide hydrolase. This approach yielded a series of rapid, selective, and highly potent inhibitors (K-i = 13 mu M to 1 nM) which in addition to their potential therapeutic value may serve as useful tools to define the biological role of oleamide.

  Inhibitors of oleamide hydrolase, responsible for the hydrolysis of an endogenous sleep-inducing lipid (1, cis-9-octadecenamide) were designed and synthesized. The most potent inhibitors possess an electrophilic carbonyl group capable of reversibly forming a (thio) hemiacetal or (thio) hemiketal to mimic the transition state of a serine or cysteine protease catalyzed reaction. In particular, the tight binding .alpha.-keto ethyl ester 8 (1.4 nM) and the trifluoromethyl ketone inhibitor 12 (1.2 nM) were found to have exceptional inhibitory activity. In addition to the inhibitory activity, some of the inhibitors displayed agonist activity which resulted in the induction of sleep in laboratory animals.
