Background

CUDC-101 is a multitargeted inhibitor of histone deacetylase. It is designed to directly inhibit epidermal growth factor receptor (EGFR) and HER2 as well as class I and class II HDACs. It has been shown that CUDC-101 is able to effectively suppress the progression of a broad range of tumor types in both in vitro and in vivo xenograft models, including lapatinib- and erlotinib-resistant cancer cell lines. Mechanistic studies provide the evidence that CUDC-101 not only directly inhibits both EGFR and HER2 signaling but also indirectly attenuates the survival signaling pathways Akt, HER3, and MET.

Protocol

Cell experiment: [1]
Cell lines	MDA-MB-231 cells
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	1 µM, 16h.
Applications	MDA-MB-231 human breast carcinoma cells showed that HGF- and EGF-induced migration was significantly reduced by 1 µM CUDC-101. The inhibition of migration and invasion was not a secondary effect of cell death or growth inhibition, as no significant decrease in cell viability under all conditions tested has been detected.
Animal experiment : [2]
Animal models	four-to 6-week-old female athymic mice (nude nu/nu CD-1) bearing human HepG2 liver cancer cell xenografts
Dosage form	After tumors reached an average of 281 mm3 in size, mice were orally treated with CUDC-101 at a daily dose of 120 mg/kg.
Applications	CUDC-101 induced 30% tumor regression. One of the treated mice displayed complete tumor regression at the end of the dosing cycle, an effect that lasted for at least 6 months after treatment.
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.
