  摘要：

  The [1,2,4]triazolo[4,3-a][1,8]naphthyridine-6-carboxamide derivatives 5-amino (2) or 5-alkoxy (3) substituted and the 5-amino[1,2,4] triazolo[4,3-a]quinoline-4-carboxamide derivatives (4), designed to obtain new effective analgesic and/or anti-inflammatory agents were synthesized. Ten compounds 2 and 4 showed an interesting analgesic activity: the most potent ones are 2j (36% inhibition, P < 0.05) and 4b (77% inhibition, P < 0.01) at 6.25 and 25 mg kg(-1) doses, respectively. Compounds 2i-I and 4c showed notable anti-inflammatory properties: the most potent ones are 2i (68% inhibition, P < 0.01) and 21 (42% inhibition, P < 0.05) at 12.5 and 6.25 mg kg(-1) doses, respectively. The replacement in compounds 2 of the N-substituted 5-amino substituents with similar alkoxy groups usually afforded less active compounds 3. (c) 2007 Elsevier Masson SAS. All rights reserved.

  摘要：

  The title compounds (8) were synthesized through the cyclocondensation of the corresponding N-substituted 4-amino-2-chloro-1,8-naphthyridine-3-carboxamides (4) with the proper hydrazides, in order to evaluate their anti-inflammatory and antiaggressive properties. Several compounds 8 exhibited high anti-inflammatory activity (carrageenin-induced paw edema assay in the rat) along with appreciable anti-aggressive properties (isolation-induced aggressiveness test in mice). With respect to anti-inflammatory activity, the most active compounds (8n and 8c) produced a 61% edema inhibition at the 25 mg/kg dose, and 50 or 35% inhibition, respectively, at the 12.5 mg/kg dose. The structure-activity relationships are discussed. (C) 2000 Editions scientifiques et medicales Elsevier SAS.
