  Synthesis and biological evaluation of the suberoylanilide hydroxamic acid (SAHA) β-glucuronide and β-galactoside for application in selective prodrug chemotherapy

  摘要：

  The beta-O-glucuronide and beta-O-galactoside of SAHA have been prepared and evaluated as prodrugs for selective cancer chemotherapy (ADEPT, PMT). These new compounds are stable under physiological conditions and do not exhibit any antiproliferative activity compared to the parent drug after a 48-h treatment of H661 cells. The glucuronide derivative did not lead to the release of the drug in the presence of either Escherichia coli or bovine liver beta-glucuronidase. On the other hand, under enzymatic cleavage of galactoside prodrug by the corresponding enzyme, a rapid release of SARA was observed demonstrating that the beta-O-galactoside of SAHA is a promising candidate for in vivo investigations.

  First O-Glycosylation of Hydroxamic Acids

  摘要：

  The first O-glycosylation of hydroxamic acids is reported. This process involves the use of glycosyl N-phenyl trifluoroacetimidates as glycosyl donors in the presence TMSOTf and 4 angstrom molecular sieves in dichloromethane. Under such conditions, a wide range of new glycosyl donors including glucosyl, galactosyl, mannosyl, glucuronyl, and ribosyl hydroxamates were prepared in good to high yields. This procedure appears to be an advantageous alternative for the synthesis of glycosyl hydroxamates of biological interest.
