Abstract

Two novel series of N-sulfonylamidino pyrimidine derivatives were synthesized via Cu-catalyzed three-component reaction of propargylated nucleobases with different benzenesulfonyl azides and amines. In this way 4-acetamido, 4-methyl and 4-carboxybenzenesulfonyl amidine products 15-26 in the uracil series and 4-acetamidobenzenesulfonyl amidine derivatives 27-29 in the cytosine series were prepared in 34-69 % yields. Attempts to prepare N-sulfonylamidino cytosine derivatives in reaction with 4-methylbenzenesulfonyl azide were unsuccessful. The cytosine derivatives 32 and 33 were prepared from the N-sulfonylamidino uracil derivatives via the C4 triazole intermediates.
The prepared N-sulfonylamidino pyrimidine derivatives 1-28 were tested for the antiproliferative activity on a panel of seven tumor cell lines of different histological origin (HeLa, Caco-2, NCI-H358, Raji, HuT78, K562, Jurkat) and on normal MDCK I cells. Most of the synthesized compounds showed antiproliferative activity on the tested cell lines.
