HSP-990 is an oral Hsp90 inhibitor being developed by Novartis in a collaboration with Vernalis. It is also known by NVP-HSP990. HSP-990 is an inhibitor of human heat-shock protein 90 (Hsp90) with potential antineoplastic activity. Hsp-990 binds to and inhibits the activity of Hsp90, which may result in the proteasomal degradation of oncogenic client proteins, including HER2/ERBB2, and the inhibition of tumor cell proliferation. Hsp90, upregulated in a variety of tumor cells, is a molecular chaperone that plays a key role in the conformational maturation, stability and function 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 and/or immune responses.
