| Research Abstract |
This project aimed to focus on the anti-invasive and anti-metastatic action of trityl group-containing sugar derivatives, to make molecular design, and to find out novel lead compounds for new anti-cancer drugs, based on the previous studies on the anti-adhesive sugar derivatives. Of more than 500 compounds investigated, 5 derivatives were finally selected to subject to a series of in vitro and in vivo tests. 5'-Trityl uibonucleosides and two tritylcyclodextrin derivatives found to be most effective cadidate for new lead compounds, because of their easy availability of both various isomers and materials, nontoxicity, and effective action in in vivo tests. Especially antiimetastatic cyclodextrins are of interest for future development. Various trityl purine and pyrimidine derivatives were studied on their anti-tumor activities. Several of them were found to be effective in growth inhibition of human cancer cell lines at the concentration of less than 10^<-6>M.One of them was found to be effective in vivo. The main features of the present study include novel biological activity of trityl group in sugars, expected new mechanism, and low toxicity..
