  Compounds of formula (I), wherein R is a hydrogen atom or a carboxy, alkoxycarbonyl, --CO--NR.sub.4 R.sub.5, --PO.sub.3 H.sub.2 or --CH.sub.2 OH radical, and R.sub.1 is an -alk-NH.sub.2, -alk-NH--CO--R.sub.3, -alk-COOR.sub.4, -alk-CO--NR.sub.5 R.sub.6 or --CO--NH--R.sub.7 radical. The compounds of formula (I) have valuable pharmacological properties and are antagonists of the .alpha.-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor also known as the quisqualate receptor. Furthermore, the compounds of formula (I) are non-competitive antagonists of the N-methyl-D-aspartame (NMDA) receptor and more specifically are ligands for NMDA receptor glycine modulator sites.

  式(I)化合物，其中R为氢原子或羧基、烷氧羰基、--CO--NR₄R₅、--PO₃H₂或--CH₂OH基团，R₁为-烷基-NH₂、-烷基-NH--CO--R₃、-烷基-COOR₄、-烷基-CO--NR₅R₆或--CO--NH--R₇基团。式(I)化合物具有宝贵的药理特性，是α-氨基-3-羟基-5-甲基-4-异噁唑丙酸(AMPA)受体即quisqualate受体的拮抗剂。此外，式(I)化合物是非竞争性N-甲基-D-天冬氨酸(NMDA)受体的拮抗剂，更具体地说是NMDA受体甘氨酸调节位点的配体。

  A novel series of 2- and 9-disubstituted heterocyclic-fused 4-oxo-indeno[1,2-e]pyrazin derivatives was synthesized. One of them, the 9-(1 H-tetrazol-5-ylmethyl)-4-oxo-5,10-dihydroimidazo[1,2-a]indeno[1,2-e]pyrazin-2-yl phosphonic acid 4i exhibited a strong and a selective binding affinity for the AMPA receptor (IC50 = 13 nM) and demonstrated potent antagonist activity (IC50 = 6 nM) at the ionotropic AMPA receptor. This compound also displayed good anticonvulsant properties against electrically-induced convulsions after ip and iv administration with ED50 values between 0.8 and 1 mg/kg. Furthermore, a strong increase in potency was observed when given iv 3 h before test (ED50 = 3.5 instead of 25.6 mg/kg for the corresponding 9-carboxymethyl-2-carboxylic acid analogue). These data confirmed that there is an advantage in replacing the classical carboxy substituents by their bioisosteres such as tetrazole or phosphonic acid groups. (C) 2001 Elsevier Science Ltd.
