Synthesis and biological evaluation of 5′-glycyl derivatives of uridine as inhibitors of 1,4-β-galactosyltransferase
摘要:
New 5'-glycyl derivatives of uridine containing fragments of varying lipophilicity were synthesized as analogues of natural peptidyl antibiotics. One of the studied compounds, 5'-O-(N-succinylglycyl)-2',3'-O-isopropylideneuridine (A4), showed moderate inhibition against 1,4-beta-galactosyltransferase. However, additional studies showed that the observed inhibitory effect was due to binding to bovine serum albumin, which was used in assays as a stabilizer. (C) 2014 Elsevier Inc. All rights reserved.
