Anti-HBV Principle from the Culture Broth of Antrodia Camphorota (Strain # CCRC-35396)

樟芝(Antrodia camphorota, strain CCRC-35396)培養液中具抗B型肝炎病毒活性成分

摘要


利用活性追蹤的分離,自樟芝(Antrodia camphorota, strain CCRC-35396)的培養液中得到一個具抗B型肝炎病毒活性之pyrroledione類化合物,利用光譜分析確認其結構爲3-isobutyl-4-{4-[(3-methyl-2-butenyl)oxy]phenyl}-2,5-dihydro-1H-2,5-pyrroledione (1)。化合物1在50μM時不產生細胞毒活性,但對B型肝炎病毒之HBsAg及HBeAg的表現分別有35.2及12.8%的抑制作用。

Bioassay-guided fractionation resulted in the isolation of an anti-HBV pyrroledione, 3-isobutyl-4-{4-[(3-methyl-2-butenyl)oxy]phenyl}-1H-pyrrole-2, 5-dione (1), from the culture broth of fungus Antrodia camphorota (strain CCRC-35396). The structure of compound 1 was determined by spectral analyses. Compound 1 suppressed both HBsAg and HBeAg expression with the moderate inhibition percentages of 35.2 and 12.8%, respectively, at the non-cytotoxic concentration of 50 μM.
