Novel imidazole derivatives as histamine receptor H3 antagonists and/or agonists, preparation thereof and therapeutical uses thereof. Chemical compounds for use as histamine receptor H3 agonists, partial agonists or antagonists, having general formula (Ia) or (Ib), the use thereof for making drugs, and methods for revealing the agonist, partial agonist or antagonist activity of such compounds in vivo, are disclosed.
Development of Chiral <i>N</i>-Alkylcarbamates as New Leads for Potent and Selective H<sub>3</sub>-Receptor Antagonists: Synthesis, Capillary Electrophoresis, and in Vitro and Oral in Vivo Activity
N-2-heptylcarbamate showed a stereoselective differentiation in their pharmacological effect in vivo (ED50 of 0.39 mg/kg for the (S)-derivative vs 1.5 mg/kg for the (R)-derivative) most probably caused by differences in pharmacokinetic parameters. H1- and H2-receptor activities were determined for some of the novel carbamates, demonstrating that they have a highly selective action at the histamine H3 receptor

isocyanates are prepared in good to excellent yields by treatment of alcohols, thiols and trimethylsilyl ethers with triphenylphosphine/2,3-dichloro-5,6-dicyanobenzoquinone/ Bu 4 NOCN in acetonitrile. This method is highly selective for conversion of primary alcohols to alkyl isocyanates in the presence of secondary and tertiary alcohols, thiols and trimethysilyl ethers.
A versatile manganese(I) catalyst was employed in CH aminocarbonylation reactions of heteroarenes with aryl as well as with alkyl isocyanates using a removable directing group approach. Detailed experimental mechanistic studies were suggestive of an organometallic CH manganesation step, followed by a rate‐determining migratory insertion.

The invention provides novel multitarget inhibitors of the enzymes Fatty Acid Amide Hydrolase (FAAH), Cyclooxygenase-1 (COX-1) and/or Cyclooxygenase-2 (COX-2) having a specific carbamate moiety on the meta or ortho position of the A ring of a substituted biphenyl core and having an halogen in the ortho position of the B ring of the biphenyl core. The invention concerns also with therapeutical application of the multitarget inhibitors in particular in the prevention and treatment of cancer.
