    摘要:
    P-糖蛋白 (P-gp)/MDR-1 通过将化疗药物泵出癌细胞并降低其疗效,在多药耐药性 (MDR) 的发展中起主要作用。据报道,当与化疗药物共同给药时,许多 P-gp 抑制剂可以逆转 MDR。不幸的是,由于毒性问题,没有一个被批准用于临床。据报道,在临床中测试的一些 P-gp 抑制剂与 CYP450 药物代谢酶有交叉反应,导致联合给药的化疗药物的药代动力学和毒性不可预测。在本研究中,两种胡椒碱类似物(3和4) 与 CYP3A4 药物代谢酶具有较低的交叉反应性,通过计算设计被鉴定为 P-糖蛋白 (P-gp) 抑制剂,然后在过表达 P-gp 的 MDR 癌细胞系中进行合成和测试 (KB Ch R 8– 5、SW480-VCR 和 HCT-15)。在低微摩尔浓度下,这两种类似物都显着提高了长春新碱在 MDR 癌细胞系中的功效。具体而言,3导致 KB Ch R 8-5 细胞中长春新碱耐药性的完全逆转,并发现它可作为

  • Boosting caffeic acid performance as antioxidant and monoamine oxidase B/catechol-O-methyltransferase inhibitor

    oxidative stress (OS) and depletion of nigrostriatal dopamine (DA) are closely linked to the neurodegeneration observed in Parkinson's Disease (PD). Caffeic acid (CA)-based antioxidants were developed, and their inhibitory activities towards monoamine oxidases (MAOs) and catechol O-methyltransferases (COMT) were screened. The results showed that the incorporation of an extra double bond maintained or even boosted
    增加的氧化应激 (OS) 和黑质纹状体多巴胺 (DA) 的消耗与帕金森病 (PD) 中观察到的神经变性密切相关。开发了基于咖啡酸(CA)的抗氧化剂,并筛选了它们对单胺氧化酶(MAOs)和儿茶酚O-甲基转移酶(COMT)的抑制活性。结果表明,额外双键的加入保持甚至增强了 CA 的抗氧化性能。α-CN 衍生物显示出与 CA ( 1 ) 相似的氧化还原电位 ( E p ),并以低 μM IC 50值抑制h MAO-B。此外,儿茶酚酰胺作为 MB-COMT 抑制剂,显示 IC 50低 μM 范围内的值。一般来说,CA 衍生物在浓度高达 10 μM 时表现出安全的细胞毒性特征。CA 衍生物诱导的活性氧 (ROS) 的形成可能是在较高浓度下观察到的细胞毒性作用的基础。10 μM 的儿茶酚酰胺3 – 6 , 8 – 11 可保护细胞免受氧化损伤。预计化合物3和8通过被动扩散穿过血脑屏障 (BBB)。总之,我们首次报道了可以恢复
