An Efficient One‐Pot Enzymatic Synthesis of Cardiac Glycosides with Varied Sugar Chain Lengths. Issue 13 (13th May 2019) - Huang, Wei
Abstract: An efficient one‐pot enzymatic synthesis of cardiac glycosides with varied sugar chain lengths (average yield >80%) was carried out through sequential glycosylation using a steroid glycosyltransferase UGT74AN3 from Catharanthus roseus and a cyclodextrin glycosyltransferase from Bacillus licheniformis . A series of cardiac glycosides were obtained and showed enhanced affinity and selectivity for inhibition of the α2 isoform of Na + /K + ‐ATPase. These findings demonstrate the significant potential of the one‐pot biocatalytic approach in the synthesis of diverse cardiac glycosides as potentially safer cardiotonic agents. Abstract :
