General information

Class/mechanism: Hsp90 (heat shock protein 90) inhibitor. Hsp90 is a molecular chaperone that stabilizes various cellular proteins, such as growth factor receptors and molecules involved in signal transduction. Hsp90 is overexpressed in cancer cells and may help to stabilize less stable proteins produced by DNA mutations. By inhibiting Hsp90, retaspimycin may accelerate degradation of growth factors and increase the sensitivity of cancer cells to environmental stress, leading to apoptosis of tumor cells.[1][2]
Route: IV
