Description of XL-888

XL-888 is a novel and orally-bioavailable inhibitor of heat shock protein 90 (HSP90) that selectively inhibits HSP90α and HSP90β with values of 50% inhibition concentration IC50 of 22 nM and 44 nM respectively. It also exerts considerably weaker inhibition against a range of other diverse kinases with IC50 more than 3600 nM for all. X-ray crystallographic analysis reveals that the XL-888 binds to HSP90 through the formation of H-bonding between the N-(R)-sec-butylanthranilamide moiety of XL-888 and ASP93 of HSP90. In recent studies, XL-888 has exhibits strong anti-proliferative activities in a panel of tumor cells with values of IC50 ranging from 0.1 nM to 45.5 nM.

Protocol of XL-888

Cell experiment [1]:

Cell lines

Vemurafenib-resistant melanoma cell lines

Preparation method

The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20 °C for several months.

Reaction Conditions

300 nM; 72 or 144 hrs

Applications

In Vemurafenib-resistant melanoma cell lines, XL888 (300 nM) induced high levels (> 66%) of apoptosis and loss of mitochondrial membrane potential.

Animal experiment [1]:

Animal models

Mice bearing M229R xenografts

Dosage form

100 mg/kg; p.o.; 3 times per week, for 15 days

Applications

XL888 (100 mg/kg) significantly induced the regression of established M229R xenografts in SCID mice.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
