Abstract: The present invention relates to a anti-proliferative target for designing chemotherapeutic agents, which comprises a EIF4A protein having an amino acid sequence, as defined in claim 1.

Abstract: The invention provides novel inhibitors of protein translation initiation and inhibitors of eIF4F activity that can increase chemosensitivity or diminish or reverse chemoresistance in growth transformed cells and thereby reduce hyperproliferative conditions, such as cancer progression, in select patient populations having particular tumor genotypes. The invention also provides methods which target translation initiation controls in growth-transformed cells, such as tumor subtypes with altered expression of a gene activity, including the human akt, bcl-2, eIF4E, eIF4A or PTEN activities, to restore drug sensitivity in vivo in a genotype selective manner. In one aspect, the inhibitors of translation initiation of the invention are rocaglates, i.e., cyclopenta[b]benzofurons, which increases chemosensitivity or diminishes or reverses chemoresistance either alone or in combination, additively or synergistically, with other agents that alter growth or death.
