in vitro. Ganomycin I (4), 5, and 8 showed stronger inhibitory activity against HMG-CoA reductase than the positive control atorvastatin. Compounds 1, and 3-8 presented potent noncompetitive inhibitory activity against α-glucosidase from both yeast and rat small intestinal mucosa. Ganomycin I (4), the most potent inhibitor against both α-glucosidase and HMG-CoA reductase, was synthesized and evaluated
从灵芝子实体中分离出三种新的类
胡萝卜素,甘露素AC(1-3),和五个已知的类
胡萝卜素(4-8)。通过广泛的光谱分析,圆二色性(CD)光谱和
化学转化来阐明新化合物的结构。在体外测试了1-8对
HMG-CoA还原酶和α-
葡萄糖苷酶的抑制作用。Ganomycin I(4),5和8对
HMG-CoA还原酶的抑制活性强于阳性对照
阿托伐他汀。化合物1、3-8对来自酵母和大鼠小肠粘膜的α-
葡萄糖苷酶均表现出强大的非竞争性抑制活性。合成了针对α-
葡萄糖苷酶和
HMG-CoA还原酶最有效的
抑制剂Ganomycin I(4),并对其体内
