摘 要:α,β-不飽和環(huán)戊酮的Mannich堿和α,β-不飽和環(huán)己酮的Mannich堿具有顯著(zhù)的抗炎活性,為了尋求新的具有抗炎活性的環(huán)酮類(lèi)化合物,設計了3,4-二氫-4-(1-哌啶甲基)-5H-1-苯并氧雜 -5-酮鹽酸鹽作為目標化合物。以苯酚、γ -丁內酯、甲醛和哌啶等原料合成了目標化合物,并利用熔點(diǎn)、紅外光譜、核磁共振氫譜等手段確定了其結構。采用二甲苯致小鼠耳腫脹法,測定了該化合物的抗炎活性,實(shí)驗結果表明在200 mg/kg劑量下該化合物對二甲苯所致小鼠耳腫脹的抑制率為54.5%。采用Born's比濁法測定了該化合物的抗血小板聚集活性,實(shí)驗結果表明該化合物的抗血小板聚集活性比噻氯匹啶強約23倍。

Synthesis and Biological Activity of 3,4-Dihydro-4-(1-piperidinomethyl)-5H-benzoxepin-5-one

Abstract:The mannich base dervatives of α,β-unsaturated cyclopentanone and cyclohexanone are known to exhibit anti-inflammatory activity. In order to find some new compounds with cyclic ketone moiety which be expected to exhibit anti-inflammatory activity,3,4-dihydro-4-(1-piperidinomethyl)-5H-benzoxepin-5-one was designed as the target compound. The target compound were synthesized from phenol, -butyrolactone,formaldehyde and piperidine as the starting raw materials,and characterized by melting point,infrared spectra and proton 1H NMR spectra. The anti-inflammatory activity was evaluated using xylene-induced mouse ear swelling model,and the inhibitory rate of 54.5% at the dose of 200 mg/kg. Using Born's method,the anti-platelet aggregative activity was evaluated,and the inhibitory activity was about 23 times more potent than that of ticlopidine.
