Molecular events that regulate cell proliferation: an approach for the development of new anticancer drugs
1Laboratoire de Chimie Biologique, UMR n(o)111 du CNRS, Villeneuve d'Ascq, France.
Abstract:
Cancer chemotherapy is the object of many fundamental and clinical researches. The development in molecular techniques and structural studies at the molecular level have led to the discovery of key proteins involved in the regulation of cell proliferation. This opened perspectives to characterize new anticancer drugs in order to reduce the limitations found with conventional drugs such as the lack of selectivity for cancer cells and resistance phenomena. This review presents the anticancer drugs in clinical investigations that target molecules involved in the signal transduction impairment, the cell cycle deregulation and the differentiation with comments on their mechanisms of action.
