A new chitinase inhibitor, named argifin, was isolated from the cultured broth of a fungal strain Gliodadium sp. FTD-0668. Argifin was purified from the cultured mycelium by the combination of cation exchange, anion exchange, adsorption, and gel filtration chromatographic methods. The structure of argifin was elucidated as cyclo(Nω-(N-methylcarbamoyl)-L-arginyl-N-methyl-L-phcnylalany1-β-l-aspartyl-β-laspartyl-D-alanyl) by NMR experiments and other spectroscopic analyses.
从真菌菌株 Gliodadium sp 的培养液中分离出一种新的几丁质酶抑制剂,名为 argifin。 FTD-0668。通过阳离子交换、阴离子交换、吸附和凝胶过滤层析相结合的方法从培养的菌丝体中纯化精氨酸。通过核磁共振实验和其他光谱分析,精氨酸的结构被阐明为环(Nω-(N-甲基氨基甲酰基)-L-精氨酰基-N-甲基-L-苯丙氨酰1-β-l-天冬氨酰-β-天冬氨酰-D-丙氨酰) 。
