  New isoxazole derivatives designed as nicotinic acetylcholine receptor ligand candidates

  摘要：

  In this work we report the synthesis and evaluation of the analgesic properties of new isosteric heterocyclic derivatives, presenting the isoxazole nucleus, designed as nicotinic acetylcholine receptor ligand candidates, analogues to alkaloid epibatidine. Compound 2-(3-methyl-5-isoxazolyl)pyridine (3) presented the best analgesic profile of this series in hot plate test, which was partially prevented by pretreatment with nicotinic receptor antagonist mecamylamine.

  Isoxazole계 화합물을 합성하고 항균활성연구를 수행하였다. 3-Di(alkylamino)acryloalkanones을 hydroxylamine hydrochloride 또는 hydroxylamine-O-sulphonic acid와 반응시켜서 target isoxazole계 화합물을 합성하였다. The synthesis, characterization and antibacterial activity of novel isoxazole derivatives were reported. 3-Di (alkylamino)acryloalkanones were prepared and used as synthons to get the target isoxazole derivatives via reaction with hydroxylamine hydrochloride or hydroxylamine-O-sulphonic acid.
