摘要: 山茶靛牛肝菌(Boletus pseudoregius)子实体中分离得到的7个化合物,通过波谱分析,分别鉴定为:烟酸(1)、腺苷(2)、琥珀酸(3)、麦角甾醇(4)、鸟苷(5)、脑苷脂B(6)和甘露醇(7),这些化合物都是首次从山茶靛牛肝菌(B.pseudoregius)子实体中获得,对化合物进一步作了体外抗肿瘤实验,结果表明,化合物2、4、5、7对肿瘤细胞K562的增殖有不同程度的抑制作用,其抑制率IC50值分别为:76.3、80.4、88.7、96.5 μg/mL,化合物2、5、7对肿瘤细胞HepG2也有明显的抑制作用,其抑制率IC50分别为93.8、98.6、97.1 μg/mL。

Abstract: Seven compounds were isolated from fruiting bodies of Boletus pseudoregius by using column chromatography.According the spectral data,they were identified as nicotinic acid (1),adenosine (2),succinic acid (3),ergosteol (4),guanosine (5),cerebroside B (6),Dmannitol (7).By in vitro cytotoxicity screening,compounds 2,4,5 and 7 were found to inhibit the proliferation of k562 tumor cells with IC50 of 76.3,80.4,88.7 and 96.5 μg/mL respectively.Compound 2,5,7 showed inhibition to the proliferations of HepG2 with IC50 of 93.8,98.6,97.1 μg/mL.
