Asymmetric reduction of hydroxynaphthoquinones to secondary metabolites, (3S,4R)-3,4,8- and (2S,4R)-2,4,8-trihydroxy-1-tetralone, a putative biosynthetic diketo intermediate and a probable natural analogue, (3S,4R)-7-acetyl-3,4,8-trihydroxy-6-methyl-3,4-dihydronaphthalene-1(2H)-one, using NADPH-dependent tetrahydroxynaphthalene reductase (T4HNR) of Magnaporthe grisea is described. This work implies
羟基萘醌不对称还原为次级代谢产物(3 S,4 R)-3,4,8-和(2 S,4 R)-2,4,8-三羟基-1-四氢萘酮,一种假定的生物合成二酮中间体和可能天然类似物,(3小号,4 - [R)-7-乙酰基3,4,8-三羟基-6-甲基-3,4-二氢萘-1(2 ħ) -酮,使用NADPH依赖性羟基萘还原酶(T描述了稻瘟病菌(Magnaporthe grisea)的4 HNR)。这项工作暗示通过减少含羟基萘醌支架的底物,在其他二氢芳烃的(生物)合成过程中,T 4 HNR或相关酶的参与。
