cell death by increasing reactive oxygen species (ROS) levels. In this study, the hydroxyls at positions C10 (10-OH) and C1 (1-OH) of GNP were hypothesized to be the active groups that cause these inhibitory effects. Four GNP derivatives in which the hydroxyl at position C10 or C1 was replaced with other chemical groups were synthesized and isolated. Differences in the inhibitory effects of GNP and its
Genipin(GNP)有效抑制解偶联蛋白2(UCP2),后者调节质子穿过线粒体内膜的泄漏。UCP2抑制可通过增加活性氧(ROS)水平来诱导胰腺腺癌细胞死亡。在这项研究中,假设GNP的C10(10-OH)和C1(1-OH)位置的羟基是引起这些抑制作用的活性基团。合成并分离了四种GNP衍生物,其中C10或C1处的羟基被其他化学基团取代。评估了GNP及其四种衍生物对胰腺癌细胞(Panc-1)增殖的抑制作用差异。还研究了GNP及其衍生物对细胞凋亡,UCP2抑制和ROS产生的影响,以探讨GNP'之间的关系。的活动及其结构。具有1-OH取代的衍生物,子苷(1-GNP1)和1-乙基-Genipinin(1-GNP2)没有细胞毒性作用,而其他保留了1-OH,10-piv-genipinin(10-GNP1)和即使没有10-OH,10-乙酸-Genipin(10-GNP2)也具有与GNP相似的生物学作用。
