A series of unprotected pseudo-disaccharides and pseudo-trisaccharides of 2-deoxystreptamine-containing aminoglycosides have been selectively acylated at the N-1 position with the valuable (S)-4-amino-2-hydroxybutanoyl (AHB) pharmacophore by using the recombinant BtrH and BtrG enzymes from butirosin biosynthesis in combination with a synthetic acyl donor. The process was optimized by performing two
通过使用重组体,在有价值的(S)-4-氨基-2-羟基丁酰基(AHB)药效基团的N-1位选择性地酰化了一系列含2-脱氧链胺胺的氨基糖苷的一系列未保护的伪二糖和伪三糖。Butirosin生物合成中的BtrH和BtrG酶与合成的酰基供体结合。通过在不纯化中间产物的情况下依次进行两个酶促步骤来优化工艺。
