Abstract:
Modifications of the potent anticancer agent taxol were carried out in order to gain an understanding of the chemical reactivity of the drug and the factors which contribute to its biological activity. The C-2' and/or the C-7 hydroxyl groups of taxol were substituted with acetyl, ßalanyl, silyl, succinyl, trichloroethyloxycarbonyl or carbonate linked dibenzylidene protected glucosyl groups. The C-7 position was selectively epimerized under free radical conditions and a 2'-epiacetyltaxol was produced via base catalysed epimerization.

Several members of the schweinfurthin family are potent and selective inhibitors of cancer cell growth in the NCI 60-cell cancer screen. The schweinfurthins display unique activity in this screen which suggests that these compounds have a previously unexploited target. This activity encourages development of the schweinfurthins as anti-cancer agents; however, the scarcity of the natural products has hindered biological evaluation. For this reason, a program was initiated to synthesize the natural products and analogues thereof. These efforts have made 5 natural product schweinfurthins and over

Abstract:
Metal-based antitumor drugs play a relevant role in antiblastic chemotherapy. Cisplatin is regarded as one of the most effective drugs, even if severe toxicities and drug resistance phenomena limit its clinical use. Therefore, in recent years there has been a rapid expansion in research and development of novel metal-based anticancer drugs to improve clinical effectiveness, to reduce general toxicity and to broaden the spectrum of activity. The variety of metal ion functions in biology has stimulated the development of new metallodrugs other than Pt drugs with the aim to obtain compounds acti

Abstract:
The mechanism of resistance of tumor cells to chemotherapeutic agents is explored using probabilistic methods where it is assumed that resistant cells arise spontaneously with a defined frequency. The resistance process is embedded in a discrete time Markov branching process which models the growth of the tumor and contains three seperate cell types: stem, transitional and end cells. Using the asymptotic properties of such models it is shown that the proportion of each type of cell converge to constants almost surely. It is shown that the parameters relating to stem cell behaviour determine th
