Sinensetin是α-葡萄糖苷酶的选择性抑制剂,IC50值为0.66 mg/ml[1]。
Sinensetin是一类主要的多甲氧基黄酮(PMF),主要存在于柑橘果皮中。据报道,sinensetin具有多种生物活性,包括抗真菌、抗突变、抗癌和抗炎[2][3]。
在人类细胞色素P450 1A2(CYP1A2)试验中,sinensetin处理可显著抑制CYP1A2活性[4]。使用Apostolidis改进的办法,sinensetin溶液与含有α-葡萄糖苷酶溶液的磷酸盐缓冲液(pH 6.9)在96孔板中25°C下孵育10 min可显著抑制α-葡萄糖苷酶[1]。在人脐静脉内皮细胞中,sinensetin处理可诱发细胞周期停滞于G0/G1期,从而抑制细胞增殖,表明其具有低毒性和抗血管生成活性[2]。在RAW 264.7细胞中,sinensetin可在蛋白水平调控κB-α表达,抑制炎症活性[3]。以sinensetin处理人类AGS胃癌细胞可提高p53和p21表达,引起增殖的抑制和细胞凋亡[5]。
在斑马鱼动物模型中,sinensetin处理可在mRNA水平下调与血管生成有关的flt1、kdrl和hras的表达[2]。
