1-Alkyl-4-acylpiperazines as a New Class of Imidazole-Free Histamine H3 Receptor Antagonists
摘要:
With the aim of identifying structurally novel, centrally acting histamine H-3 antagonists, arrays of monoacyldiamines were screened. This led to the discovery of a series of 1-alkyl-4-acylpiperazines which were potent antagonists at the human histamine H-3 receptor. The most potent amides had antagonist potencies in the subnanomolar range.

regioselective, and convergent method for the ring expansion and rearrangement of 1‐sulfonyl‐1,2,3‐triazoles under rhodium(II)‐catalyzed conditions is described. These denitrogenative reactions form substituted enaminone and olefin‐based products (see scheme). The enaminone products can be further functionalized to give various heterocycles and ketonederivatives, thus rendering the sulfonyl triazole traceless

The present invention comprises alkylpiperazine- and alkylhomopiperazine carboxylates and their derivatives, methods for their preparation and the therapeutic use thereof as fatty acid amido hydrolase (FAAH) enzyme inhibitors. These derivatives exert various pharmacological activities by interacting, inter alia, with cannabinoid and vanilloid receptors. By inhibiting the metabolic activity of the FAAH enzyme, compounds often responsible for the onset of disease and other pathological conditions are not generated and the incidence of the disease is greatly reduced.
