Koenimbine (1), a carbazole alkaloid isolated from Murraya koenigii, belongs to the Rutaceae family. Various pharmacological effects such as anti-diabetic, melanogenesis inhibition, anti-diarrheal, anti-cancer, and anti-inflammatory properties of koenimbine have already been reported. In the current study, we investigated the anti-inflammatory role of koenimbine (1) and its novel semi-synthetic derivative
Koenimbine ( 1 ) 是一种从九里香中分离出来的咔唑生物碱,属于芸香科。 koenimbine 的多种药理作用,如抗糖尿病、抑制黑素生成、抗腹泻、抗癌和抗炎特性,已被报道。在本研究中,我们研究了koenimbine ( 1)及其新型半合成衍生物8-甲氧基-3,3,5-三甲基吡喃并[3,2-a]咔唑-11(3H)-yl 的抗炎作用) (3-(三氟甲基)苯基)甲酮 ( 1G)在体外和体内生物系统中。我们的结果表明,LPS 刺激 RAW 264.7 巨噬细胞后, 1G的抗炎活性显着降低了 NO、促炎细胞因子(IL-6、TNF-α 和 IL-1β)、LTB4 的产生。此外, 1G以剂量依赖性方式显着减弱一氧化氮合酶 (iNOS) 和环氧合酶-2 (COX-2) 的表达水平,并减少 LPS 激活的 RAW 264.7 细胞中活性氧 (ROS) 的产生。此外,口服1G可减轻BALB/C小鼠
