synthesis of acylphloroglucinol 3‐C‐glucosides from 2‐O‐glucosides was exploited using a novel C‐glycosyltransferase (MiCGTb) from Mangifera indica. Compared with previously characterized CGTs, MiCGTb exhibited unique de‐O‐glucosylation promiscuity and high regioselectivity toward structurally diverse 2‐O‐glucosides of acylphloroglucinol and achieved high yields of C‐glucosides even with a catalytic amount
使用来自Mangifera india的新型C-糖基转移酶(MiCGTb)开发了一种绿色且经济高效的方法,可从2- O-葡萄糖苷方便地合成酰基间苯三酚3- C-葡萄糖苷。与先前表征的CGT相比,MiCGTb对酰基间葡糖醇的结构多样的2- O-葡萄糖苷表现出独特的de- O-葡萄糖基混合性和高区域选择性,即使催化量的尿苷5'-二磷酸(UDP)也可实现高产量的C-葡萄糖苷。这些发现首次证明了单一酶方法在生物活性C合成中的巨大潜力。天然和非天然酰基间苯三酚2- O-葡糖苷中的葡糖苷。
