syntheses of six new hybrids compounds (4–9) that were efficiently prepared in one or two steps (70–84.6%) from our previous prototype (±)-cis-4-chloro-6-(naphthalen-1-yl)-tetrahydro-2H-pyran-2-yl)methanol (3) and the NSAIAs: acetyl salicylic acid, indomethacin, ibuprofen, ketoprofen, naproxen and diclofenac. The acetic acid-induced writhing method is able to determine that all investigated new hybrids showed
我们提出了本文的六个新的杂交体的化合物(合成在4 - 9)从我们以前的原型在一个或两个步骤(70-84.6%)被有效地制备该(±) -顺式-4-氯-6-(萘1-基)-四氢-2 H-吡喃-2-基)甲醇(3)和NSAIAs:乙酰水杨酸,消炎痛,布洛芬,酮洛芬,萘普生和双氯芬酸。乙酸诱导的扭体法能够确定所有研究的新杂种均显示出比其前体更强的抗伤害感受特性(ED 50值低2至10倍)。对于化合物9观察到最高的镇痛作用,显示出比ED 50低10倍以上值比双氯芬酸低,ED 50值比化合物2低9倍。在甩尾试验中,所有化合物均表现出比对照组更大的活性,从而证实了中枢镇痛作用。通过旋转杆性能和开放视野测试,新的杂种不会改变小鼠的运动能力。研究的化合物4 - 9是没有毒性(LD口服后50 > 2000毫克/千克)。
