, p. 610 - 614 (2001)
The synthesis has been achieved of a series of 9-substituted derivatives of 6-(4-nitroimidazol-5-yl)- and 6-(5-nitroimidazol-4-yl)thiopurines by the reaction of 6-(nitroimidazolyl)thiopurines with alkyl and aralkyl halides, haloalcohols, haloacids and the
Modified Nucleobases with Uniform H-Bonding Interactions, Homo- and Hetero-Basepair Bias, and Mismatch Discrimination

Paragraph 0013, (2021/07/30)
Described herein are divalent nucleobases that each binds two nucleic acid strands, matched or mismatched when incorporated into a nucleic acid or nucleic acid analog backbone, such as in a γ-peptide nucleic acid (γPNA). Also provided are genetic recognition reagents comprising one or more of the divalent nucleobases and a nucleic acid or nucleic acid analog backbone, such as a γPNA backbone. Uses for the divalent nucleobases and monomers and genetic recognition reagents containing the divalent nucleobases also are provided.

Introducing purine bases to P2-ligands might enhance the potency of Human Immunodeficiency Virus-1 (HIV-1) protease inhibitory because of the carbonyl and NH groups promoting the formation of extensive H-bonding interactions. In this work, thirty-three compounds are synthesized and evaluated, among which inhibitors 16a, 16f and 16j containing N-2-(6-substituted-9H-purin-9-yl)acetamide as the P2-ligands along with 4-methoxylphenylsulfonamide as the P2′-ligand, display potent inhibitory effect on the activity of HIV-1 protease with IC50 43 nM, 42 nM and 68 nM in vitro, respectively.
Diversity-oriented chemical modification of heparin: Identification of charge-reduced N-acyl heparin derivatives having increased selectivity for heparin-binding proteins
Huang, Liusheng,Kerns, Robert J.
, p. 2300 - 2313 (2007/10/03)
The diversity-oriented chemical modification of heparin is shown to afford charge-reduced heparin derivatives that possess increased selectivity for binding heparin-binding proteins. Variable N-desulfonation of heparin was employed to afford heparin fract
