This invention discloses a process for the use of a novel organism belonging to the genus Trichosporon sp. as whole wet or dry cell culture or cell free extract or crude enzyme or pure isolated enzyme. The strain of Trichosporon sp. used in the process is designated as RRLY-15 and has been deposited in Deutsche Sammlung von Mikroorganismen und Zellekulturen GmbH (DSMZ). The invention also discloses the preparation of S(+)-6-methoxy-2-naphthalene acetic acid (naproxen) of formula (2) through enantioselective hydrolyis of a racemic mixture of alkyl esters of (±)-6-methoxy-α-methyl-2-naphthalene acetic acid of formula (1) where R represents -CH3,-C2H5,-C3H7,-C4H9 and the like and S(+)- Naproxen is a medicinally important non steroidal anti-inflammatory drug.
本发明公开了一种使用属于 Trichosporon sp.属的新型生物的工艺,该生物为全湿或干细胞培养物或无细胞提取物或粗酶或纯分离酶。该工艺中使用的 Trichosporon sp.菌株被命名为 RRLY-15,并已存入 Deutsche Sammlung von Mikroorganismen und Zellekulturen GmbH (DSMZ)。本发明还公开了通过式(1)的(±)-6-甲氧基-α-甲基-2-萘乙酸的烷基酯的外消旋混合物的对映体选择性水解制备式(2)的 S(+)-6-甲氧基-2-萘乙酸(萘普生),其中 R 代表 -CH3、-萘普生是一种重要的非甾体抗炎药物。
