There is provided a convenient and inexpensive method of producing a compound which has a high activity of inhibiting replication of hepatitis C virus (HCV) and is useful for preventing and treating a liver disease caused by HCV infection.
It is a method of biologically producing a compound represented by the formula (1):
[wherein A represents a hydrogen atom, a straight or branched alkyl group having 1 to 8 carbon atoms, or the like], or a pharmaceutically acceptable salt thereof, a method comprising adding an amino acid derivative represented by the formula (3):
[wherein A has the same meaning as defined for the compound of the above formula (1); and R represents a hydrogen atom, a straight or branched alkyl group having 1 to 8 carbon atoms, or the like],
or a salt thereof into the fungal mycelium or the culture medium/culture broth of a filamentous fungal strain having an ability to produce the compound represented by the formula (2):
to thereby cause the fungal strain to directly produce the compound of the formula (1).
提供了一种方便且廉价的方法,用于生产一种具有高抑制丙型肝炎病毒(HCV)复制活性的化合物,并且可用于预防和治疗由HCV感染引起的肝病。这是一种生物学生产一种由以下化学式(1)表示的化合物的方法:[其中A代表氢原子、具有1至8个碳原子的直链或支链烷基基团,或类似物],或其药学上可接受的盐的方法,包括将由以下化学式(3)表示的氨基酸衍生物添加到具有生产由以下化学式(2)表示的化合物的能力的丝状真菌菌株的真菌菌丝或培养基/培养液中,从而使真菌菌株直接产生化合物的化学式(1)。
