Abstract |
Genistein, a naturally occurring soy isoflavonoid, displays antitumor, antioxidant and antiinflammatory properties. It inhibits the activity of topoisomerases and several protein-tyrosine kinases. Genistein is capable of binding to the estrogen receptor. These activities, along with low toxicity, make genistein an important candidate for experimental anticancer therapy, as well as new lead-compound for anticancer drug design [1]. The principal aim of this study was the synthesis of glycoconjugates, which are the drug candidates in antitumor therapy research program. The sugar part is connected to isoflavonoid ring system through a carbonic chain. Our thesis is that the structure modification of glycoconjugates should enhance the bioavailability of these compounds. Therefore, we decided to carry out reactions of glycals with glycosyl acceptors - derivatives of genistein, and we obtained glycoconjugates with high α –stereoselectivity [2]. This new class of substances was shown to possess anticancer activity. Cytotoxic activity of genistein glycoconjugates was evaluated against the model cell lines. Active derivatives were processed for subsequent in vitro toxicity test. For each active derivative IC50 values were obtained. It was found, that all new compounds inhibit proliferation of various cancer cells. Acknowledgementα References |
