Phosphate-Modified Nucleotides: Conversions in Human Serum

Abstract

Mechanisms and rates of hydrolytic dephosphorylation of 5′-hydrogenphosphonates, 5′-phosphorofluoridates, and 5′-phosphates of natural and 3′-substituted thymidines in human serum were studied. The stability of 5′-phosphonates of 2′-deoxy- and 2′,3′-dideoxyadenosines in calf and human sera was found.
