Although the mechanism of action remains to be fully elucidated, Hsp90 antagonist KW-2478 appears to inhibit Hsp90, resulting in impaired signal transduction, inhibition of cell proliferation, and the induction of apoptosis in tumor cells. HSP90 is a molecular chaperone that plays a key role in the conformational maturation of oncogenic signaling proteins, such as HER2/ERBB2, AKT, RAF1, BCR-ABL, and mutated p53, as well as many other molecules that are important in cell cycle regulation or immune responses."}]
