Nucleoside dimers analogues with a 1,2,3-triazole linkage: conjugation of floxuridine and thymidine provides novel tools for cancer treatment. Part II

Abstract

The fluorinated nucleoside dimers with a 1,2,3-triazole linkage are novel compounds within the field of bioorganic chemistry. We report on the synthesis and properties of two groups of nucleoside dimers analogs possessing a different arrangement of the 1,4-disubstituted 1,2,3-triazole linkage. Based on analysis of the ³J_HH, ³J_H1′C2, and ³J_H1′C6 we estimated conformational preferences of sugar part and orientation around glycosidic bond. These compounds show moderate anticancer activity, with cytostatic studies in three different cancer cell lines.
