To discover analgesics for treating chronic pain 17 novel Schiff’s bases, N,N′-(Z-allylidene-1,3-diyl)bisamino acid methyl esters were prepared from 1,1,3,3,-tetramethoxypropane and amino acid methyl esters. On tail-flick mouse model 20 μmol/kg of these Schiff’s bases were orally administered, the analgesic action started 30 min after administration, reached the maximum 120 min after administration
为了发现用于治疗慢性疼痛的镇痛药,使用了17种新型席夫碱,由1,1,3,3,-四甲氧基丙烷和氨基酸甲酯制备了N,N '-(Z-亚芳基-1,3-二基)双氨基酸甲酯。在甩尾小鼠模型上口服施用20μmol/ kg的这些Schiff碱,镇痛作用在给药后30分钟开始,在给药后达到最大120分钟,并且在180分钟时仍观察到这种作用。在二甲苯诱导的耳部水肿小鼠模型中,这些席夫碱的20μmol/ kg表现出理想的抗炎症作用。因此,本发明的希夫氏碱能够治疗炎症引起的慢性疼痛。用3D QSAR解释了这些席夫氏碱的氨基酸残基的侧链对镇痛活性的影响。
