Cell lines

Human cutaneous T-cell lymphomas (CTCL) 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 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.

Reaction Conditions

IC50: 0.146 μM HH 2.062 μM HuT78 2.697 μM MJ 1.375 μM MylA 1.510 μM SeAx 72h

Applications

Vorinostat dose-dependently reduced cell proliferation with IC50 values of 0.146 μM, 2.062 μM, 2.697 μM, 1.375 μM and 1.510 μM in HH, HuT78, MJ, MylA and SeAx cells, respectively.

Animal models

C57BL/6 mice bearing Eμ-myc lymphomas

Dosage form

C57BL/6 mice bearing Eμ-myc lymphomas were injected with vorinostat (200 mg/kg i.p.) and lymphoma cells were harvested after the indicated time points. The percentage of tumor cells in the lymph node of C57BL/6mice bearing Eμ-myc lymphomas treated with vorinostat was determined by FACS analysis.

Applications

Vorinostat induced a marked accumulation of Eμ-myc lymphomas displaying DNA fragmentation in vivo.

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.

Vorinostat (suberoylanilide hydroxamic acid, SAHA) is a histone deacetylase inhibitor (HDACi), that plays key roles in epigenetic or non-epigenetic regulation, inducing growth arrest, differentiation and apoptosis of tumor cells.^[1]Vorinostat is a small molecular with the formular of C₁₄H₂₀N₂O₃and molecular weight of 264.3. The major mechanism of HDACi-induced apoptosis is the activation of the intrinsic apoptotic pathway. HDACi can activate the intrinsic apoptotic pathway by releasing of cytochrome c from mitochondria and regulating of Bcl-2 family expression.^[2]
