  3′-Oxo-, amino-, thio- and sulfone-acetic acid modified thymidines: Effect of increased acidity on ribonuclease A inhibition

  摘要：

  A family of 3'-functionalized thymidines carrying XCH2COOH (X = O, NH, S, SO2) groups has been designed as inhibitors of RNase A. This is because it is possible to manipulate the overall acidity of this new class of nucleic 'acids' by changing X from oxygen to the SO2 group in the series. It is also expected that the acyclic nature of the XCH2COOH group would provide enough flexibility to the -COOH group to have maximum interactions with the catalytic subsite P-1 of RNase A. As the -SO2CH2COOH substituted derivative showed better potency partially because of the increased acidity of the -COOH group, the inhibitory properties of both 5'-substituted and 3',5'-disubstituted sulfone acetic acid modified thymidines were investigated. Two -SO2CH2COOH groups were incorporated with the expectation of targeting two phosphate binding sites simultaneously. Thus, 3',5'-dideoxy-3',5'-bis-S-[(carboxymethyl)sulfonyl]thymidine emerged as the best inhibitor in this series with a K-i value of 25 +/- 2 mu M. (C) 2013 Elsevier Ltd. All rights reserved.
