  Synthesis and Pharmacological Evaluation of New Pyrazolidine-3,5-diones as AT₁ Angiotensin II Receptor Antagonists

  摘要：

  On the basis of the structure of the non-peptide receptor antagonist irbesartan, a new series of AT(1) ligands was designed. In these compounds the central imidazolone nucleus of irbesartan was replaced by a pyrazolidine-3,5-dione structure. The key intermediate N-alkylpyrazolidine3,5-dioneswere synthesized according to a new and general method. The most active compounds possess a spirocyclopentane ring at position 4, a linear butyl chain at position 1, and the [2'-(5-tetrazolyl)biphenyl-4-yl]methyl or [2'-(benzoylaminosulfonyl)biphenyl-4-yl] group at position 2. Affinity toward the AT(1) and AT(2) receptors was assessed by the ability of the compounds to competitively displace [H-3]AII from its specific binding sites. The most active compounds, 28 and 48, displayed high affinity for the AT(1) receptor, good selectivity AT(1) versus AT(2), and potent in vitro antagonist activity.
