A series of heterocycle substituted 1-aryl-4-piperidones were prepared via Knoevenagel condensations between nitrogen-containing 5-membered heterocycles and benzaldehyde (1) followed by reduction or amination. The oxadiazolidinedione ring was formed by reacting the N-hydroxyurea (10) with methyl chloroformate and sodium hydride.
New oxadiazolidinedione derivatives as potent and selective human β3 agonists
investigation into the development of potent and selectivehuman beta3 agonists, a series of thiazolidinedione analogues was prepared and evaluated for their biological activity on the human beta3-adrenergic receptor. The oxadiazolidinedione derivative 17 was found to be the most potent and selective compound in this study, with an EC50 value of 0.02 microM at the beta3 receptor, 259-fold selectivity over the beta1
