Based on structure activity analysis of morphine related opiates, we have synthesized some novel benzopyran fused isoxazolidines (2a-e) and derived conformationally constrained β2,3,3-amino alcohols (3a-e), which were evaluated in vivo for their anti-nociceptive activity through acetic acid induced writhing test (peripheral) and formalin induced algesia (central). Results showed that, compound 2a possesses
基于吗啡阿片剂相关的结构活性分析,我们已经合成了一些新颖的苯并吡喃稠合异恶唑烷(2A-E )和衍生的构象约束的β 2,3,3 -氨基醇(3A-E ),该评价在体内对它们的抗-通过乙酸引起的扭体试验(周围)和福尔马林引起的痛觉过敏(中央)产生伤害感受。结果表明,化合物2a具有显着的阿片样物质激动剂活性。此外,分子对接分析表明,化合物2a与δ阿片受体(DOR)的D得分比与μ(MOR)和κ相对更好。(KOR)受体。直至2000 mg kg -1剂量,化合物2a均未显示任何毒性。
