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).
本发明提供了一种简便廉价的化合物生产方法,该化合物具有抑制丙型肝炎病毒(HCV)复制的高活性,可用于预防和治疗由 HCV 感染引起的肝病。
这是一种以生物方法生产由式(1)代表的化合物的方法:
[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或类似物],或其药学上可接受的盐,该方法包括加入由式(3)代表的氨基酸衍生物:
[其中 A 的含义与上式(1)化合物的定义相同;R 代表氢原子、具有 1 至 8 个碳原子的直链或支链烷基或类似物]、
或其盐加入具有产生式(2)所代表化合物能力的丝状真菌菌株的真菌菌丝体或培养基/培养液中:
从而使真菌菌株直接产生式(1)化合物。
