Thio-nucleosides, characterized by the replacement of an oxygen atom with a sulfur atom in the nucleobase or sugar moiety, exhibit unique chemical and biological properties that make them promising candidates for therapeutic applications. In this study, we investigate the antiproliferative activity of four thio-nitrogen bases and nucleosides, including 2-mercaptopurine, thioguanine, 6-thioguanosine, and 2'-deoxy-6-thioguanosine, as well as Desulfated Aztreonam and 2-(Benzylsulfanyl)-1-hydroxyadenosine, against the MCF-7 human breast adenocarcinoma cell line.
