6-aminoalkyloxazolo[4,5-b]pyridin-2(3H)-ones incorporating structural modifications both in the alkyl chain and basic amino moiety were tested for their analgesic efficacy and safety in mice and rats. Two of the synthesised compounds, 4a (3-methyl-6-[(4-phenyl-1-piperazinyl)methyl]oxazolo[4,5-b]pyridin-2(3H)-one) and 12a (3-methyl-6¿1-[2-(4-phenyl-1-piperazinyl)ethan-1-ol]¿oxazolo[4,5-b]pyridin- 2(3H)-one) were
测试了一系列在烷基链和碱性氨基部分均具有结构修饰的6-氨基烷基恶唑并[4,5-b]吡啶-2(3H)-酮在小鼠和大鼠中的镇痛效果和安全性。两种合成的化合物4a(3-甲基-6-[((4-苯基-1-哌嗪基)甲基]恶唑并[4,5-b]吡啶2-2(3H)-one)和12a(3-甲基-发现在ED50作用下,6¿1-[2-(4-苯基-1-哌嗪基)乙-1-醇]恶唑并[4,5-b]吡啶-2-2(3H)-一比阿司匹林更有效。 po(小鼠,苯醌扭曲试验)分别为26(16.1-42.4)和15.5(11.4-21.2)mg / kg,po(大鼠,乙酸)6(3.1-9.8)和5.5(3.5-8.8)扭转测试)。化合物4a和12a被证明是有效的非阿片类非抗炎镇痛药,但不幸的是,在相对较低的剂量下(分别为64和16 mg / kg po,小鼠)具有镇静作用。
