The present study reports the synthesis of cinnamide derivatives and their biological activity as inhibitors of both cholinesterases and anticancer agents. Controlled inhibition of brain acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) may slow neurodegeneration in Alzheimer's diseases (AD). The anticholinesterase activity of phenylcinnamide derivatives was determined against Electric Eel
本研究报告了肉桂酰胺衍生物的合成及其作为胆碱酯酶和抗癌剂抑制剂的生物活性。对大脑乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BChE)的受控抑制可能会减缓阿尔茨海默氏病(AD)中的神经变性。确定了苯基肉桂酰胺衍生物对Eel乙酰胆碱酯酶(EeAChE)和马血清丁酰胆碱酯酶(hBChE)的抗胆碱酯酶活性,某些化合物似乎是EeAChE和hBChE的中等有效抑制剂。化合物3-(2-(苄氧基)苯基)-N-(3,4,5-三甲氧基苯基)丙烯酰胺(3i)具有IC 50的最大抗EeAChE活性0.29±0.21μM,而3-(2-氯-6-硝基苯基)-N-(3,4,5-三甲氧基苯基)丙烯酰胺(3k)被证明是hBChE最有效的抑制剂,IC 50为1.18± 1.31μM 。为了更好地了解最具活性的化合物对胆碱酯酶的酶-抑制剂相互作用,对高分辨率晶体学结构进行了分子建模研究。还评估了合成化合物对癌细胞系(肺癌)的抗癌作

This invention relates to analogs of 3-0-Acetyl-11-Keto-b-Boswellic acid (AKBA) that exhibit 5-Lipoxigenase inhibitory properties. These compounds may be used in pharmaceutical compositions for therapeutic applications against a variety of inflammations and hypersensitivity-based human diseases including asthma, arthritis, bowel diseases such as ulcerative colitis and circulatory disorders such as shock and ischemia. These compounds also inhibited the growth of brine shrimp in cultures, which may be considered as a positive indication for cytotoxicity and antitumor activity.
这项发明涉及3-0-乙酰基-11-酮-β-乳香酸(AKBA)的类似物,具有5-脂氧合酶抑制性质。这些化合物可用于制备药物组合物,用于治疗各种炎症和基于过敏的人类疾病,包括哮喘、关节炎、溃疡性结肠炎等肠道疾病以及休克和缺血等循环障碍。这些化合物还抑制了培养中虾子的生长,这可能被视为细胞毒性和抗肿瘤活性的积极指标。
