生物活性
XL888 is an orally bioavailable, ATP-competitive HSP90 inhibitor with potential antineoplastic activity. XL888 specifically binds to Hsp90, inhibiting its chaperone function and promoting the proteasomal degradation of oncogenic signaling proteins involved in tumor cell proliferation and survival. XL888 potently inhibited cell growth, induced apoptosis, and prevented the growth of vemurafenib-resistant melanoma cell lines in vitro and in vivo. XL888 (100 mg/kg) significantly induces the regression or growth inhibition (50%) of established M229R and 1205LuR xenografts in SCID mice. XL888 treatment increased BIM expression, decreased Mcl-1 expression, and induced apoptosis more effectively than dual mitogen-activated protein-extracellular signal-regulated kinase/phosphoinositide 3-kinase (MEK/PI3K) inhibition.
