ethers were previously synthesized and the potential anti-inflammatory and antinociceptive activities of these compounds were evaluated in vivo. The compounds displayed a very good activity against both carrageenan-induced hyperalgesia and oedema in the rat paw test. Therefore, in a very preliminary test, compounds (8a,b) showed antiproliferative activity in the HaCaT (aneuploid immortal keratinocyte from
先前已合成了一系列取代的1,5-二芳基吡咯-3-烷氧基乙基醚,并在体内评估了这些化合物的潜在抗炎和镇痛活性。该化合物在鼠爪试验中对角叉菜胶诱导的痛觉过敏和浮肿均显示出非常好的活性。因此,在非常初步的测试中,化合物(8a,b)在HaCaT(来自成年人类皮肤的非整倍体永生角质形成细胞)细胞模型中显示出抗增殖活性。在此基础上,我们继续进行氟化衍生物(8c,d,9b - d和10b - d的合成)的研究。),目的是改善以前的活性化合物的药代动力学特性。氢原子被氟原子取代可能会由于立体电子效应而改变分子的构象偏好,并且氟原子也可能会产生代谢障碍,从而降低“首过效应”。化合物10b显示出显着的体内抗炎和抗伤害感受活性,此外,本文描述了其在人皮肤癌的体外模型中的抗增殖能力。
