An objective of the present invention is to provide novel cyclic depsipeptide derivatives and harmful organism control agents including the same as each other. Specifically, the present invention provides compounds represented by formula (1) or stereoisomers thereof, harmful organism control agents containing them, and a process for producing them.
The invention relates to nonadepsipeptides and process for their preparation, and to their use for producing medicaments for the treatment and/or prophylaxis of diseases, in particular bacterial infectious diseases.
multienzyme cascade for the asymmetric synthesis of D-amino acids from renewable fatty acids was developed. Combination of P450 peroxygenase with two enantiocomplementary hydroxyacid oxidase(s) enabled the regioselective oxyfunctionalization of fatty acids into prochiral α-ketoacids with internal H2O2 recycling. An engineered D-amino acid dehydrogenase with formate dehydrogenase for self-recycling of the
可再生脂肪酸的生物催化区域选择性和立体选择性功能化用于可持续合成增值手性化学品是非常可取的,但仍然是一个巨大的挑战。在此,开发了用于从可再生脂肪酸不对称合成D-氨基酸的三步一锅多酶级联反应。P450 过氧化酶与两种对映体互补的羟基酸氧化酶的组合使脂肪酸能够区域选择性氧化功能化为具有内部 H 2 O 2循环的前手性 α-酮酸。一种工程化的D-氨基酸脱氢酶和甲酸脱氢酶用于自循环昂贵的辅因子 NADPH,用于将 α-酮酸还原胺化为D-氨基酸。不同链长的各种脂肪酸(C 6 –C 10)可高效转化为相应的D-氨基酸,产率高(高达99%),ee值优异(>99%)。这项研究利用了级联的优势,并展示了从廉价的可再生原料中合成有价值的手性化学品的潜力。
