A series of twenty-five derivatives of tetrahydro-beta-carbolines 1-3 was synthesized and assayed on FAAH and TRPV1 and TRPA1 channels. Four carbamates, that is, 5a,c,e, and 9b inhibited FAAH with significant potency and interacted also effectively with TRPV1 and TRPA1 nociceptive receptors, while ureas 7b,d,f, and 8a,b were endowed with specific submicromolar TRPV1 modulating activities.

Herein, we report the development of a tailored cobalt catalyst system of Cp*Co(III)(LX) toward intramolecular C-H nitrene insertion of azidoformates to afford cyclic carbamates. The cobalt complexes were easy to prepare and bench-stable, thus offering a convenient reaction protocol. The catalytic reactivity was significantly improved by the electronic tuning of the bidentate LX ligands, and the observed
The invention relates to a preparation process for making peroxy esters and peroxy carbonates, peroxy ester peroxy carbonates, mixed diperoxides, mixed diperoxy esters, and mixed diperoxy carbonates, and to specific monoperoxy esters, monoperoxy carbonates, mixed peroxides, mixed diperoxy esters, mixed diperoxy carbonates, peroxy ester peroxy carbonates, and mixtures thereof. The process involves the reaction of a type-3 ketone peroxide with a reactive carbonyl compound and optional subsequent reaction with an alkyl vinyl ether, acetal, halogen formate, or carboxylic acid anhydride.

N-Arachidonoylserotonin (AA-5-HT, 1a) is an inhibitor of fatty acid amide hydrolase (FAAH) that acts also as an antagonist of transient receptor potential vanilloid-type 1 (TRPV1) channels and is analgesic in rodents. We modified the chemical structure of 1a with the aim of developing "hybrid" FAAH/TRPV1 blockers more potent than the parent compound or obtaining analogues with single activity at either of the two targets to study the mechanism of the analgesic action of 1a. Thirty-eight AA-5-HT analogues, containing a serotonin "head" bound to a variety of lipophilic moieties via amide, urea, or carbamate functionalities, were synthesized. Unlike 1a, most of the new compounds possessed activity at only one of the two considered targets. The amides 1b and 1c of alpha- and gamma-linolenic acid, however, showed "hybrid" activity similar to 1a. The carbarnate 3f (OMDM 106), although unable to antagonize TRPV1 receptors, was the most potent FAAH inhibitor in this study (IC50 = 0.5 mu M). Compounds 3f and 1m (OMDM129), which exhibited activity at only FAAH or TRPV1, respectively, were 10-fold less potent than 1a at preventing formal in-induced hyperalgesia in mice.

The evaluation of a series of piperazinyl carbamates and ureas, designed on the basis of previously reported TRPV1 antagonists and FAAH inhibitors, led to the identification of some 'dual-action' compounds targeting both FAAH and TRPV1 or TRPA1 receptors. (C) 2009 Elsevier Ltd. All rights reserved.
