Enzymatic glycosylation catalyzed by glycosyltransferases has great potential for creating bioactive glycosylated small-molecule compounds. Here, we highlight the aglyconpromiscuity of a new glycosyltransferase (PlGT7) from Pueraria lobata. PlGT7 exhibited the capability to glycosylate 26 structurally diverse drug-like scaffolds and simple phenolics with UDP-glucose to form O-, S-, and N-glycosides

Abstract A new benzophenone glycoside, 2,6-dihydroxy-4-O-β- d -glucopyranosylbenzophenone (1), was isolated from the leaves of guajava L. Its structure was elucidated by spectral and chemical methods. 1 showed significant activities to secretion of NO in mouse peritoneal macrophages in 10 μmol/L.
