  取代基对 Novozym 435 脂肪酶区域选择性酰化核苷的影响

  摘要：

  在 Novozym 435 介导的各种 2' 或 5 取代核苷与携带不同脂肪链长度（C6、C10 和 C14）的酰基供体的酰化中，成功地进行了底物识别的比较研究。出乎意料的结果表明，核苷中取代基的物理化学性质（如大小、疏水性和取代位置）对酶的行为产生了深远的影响。源自核苷 2'-或 5-位取代基的不同底物结合模式可以解释这一点。此外，除了脂肪酶活性位点的几何构型之外，控制区域选择性的另一个可能因素可能归因于取代基和酰基供体之间的相互作用。

• A useful and versatile procedure for the acylation of nucleosides through an enzymic reaction

  Lipase-mediated acylation of nucleosides with oxime esters in organic solvents has been achieved. Candida antarctica lipases (SP435 and SP435A) showed high regioselectivity toward the primary hydroxyl group of both deoxy- and ribonucleosides, whereas other lipases exhibited poor results for this goal. 2'-Deoxynucleosides, such as thymidine and 2'-deoxyadenosine, were acylated with oxime esters carrying saturated, unsaturated, aromatic, and functionalized chains, giving 5'-O-acylated compounds together with small quantities of the 3'-O-acylated regioisomer. Uridine, adenosine, and inosine, as representative ribonucleosides, were acylated exclusively at the 5'-OH by using the same methodology. Nucleosides bearing a cytosine ring were found to be unreactive with oxime esters under the same conditions. 2'-Deoxycytidine was acylated with acid anhydrides and C. antarctica lipase to give N,5'-O-diacylated compounds, whereas cytidine gave mixtures, reason for which it had to be previously chemically N-acylated and then subjected to the oxime esters and lipase, giving the same results as ribonucleosides.

  comparative study on the substrate recognition was conducted successfully in Novozym 435-mediated acylation of various 2′- or 5-substituted nucleosides with acyl donors carrying different aliphatic chain lengths (C6, C10, and C14). The unexpected results revealed that the physicochemical property of the substituents (such as the size, hydrophobicity, and substitutional position) in nucleosides profoundly influenced
