Cell experiment: [1] | |
Cell lines |
Dexamethasone –sensitive human multiple myeloma (Dex-sensitive MM.1S) 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 |
20 nM 24-, 48-, or 72-hour |
Applications |
As an inhibitor of HDAC, LAQ824 induces apoptosis in multiple myeloma cell lines resistant to conventional therapies. In this experiment, Dex or LAQ824 alone produced only 15% and 7% growth inhibition, respectively, but produced 51% inhibition when used in combination. |
Animal experiment : [2] | |
Animal models |
Female BALB/c mice administered 32D.p210 leukemic cells via tail vein injection |
Dosage form |
The mice were given intraperitoneal injection of either 25 mg/kg LAQ824 or D5W vehicle on a daily basis, beginning 3 days after introduction of the leukemic cells. |
Applications |
Treatment of mice with LAQ824 delayed the onset of symptoms of leukemia and lethality as compared to mice treated with the vehicle control. Median survival times were 20 days in the LAQ824-treated mice and 15.5 days in the vehicle control 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. |

LAQ824 (also known as NVP-LAQ824 or Dacinostat), a derivative of 4-aminomethylcinnamic hydroxamic acid, is a novel and potent inhibitor of histone deacetylase (HDAC) that inhibits the activity of HDAC with 50% inhibition concentration IC50 value of 0.03 μM. LAQ824 has been found to inhibit the growth of a variety of cancer cell lines, including colon cancer H1299 and HCT116 cells, breast cancer MDA435 cells, prostate cancer DU145 and PC3 cells and non-small cell lung cancer A549 cells, with IC50 value < 1 μM and induce apoptosis in human breast cancer SKBR-3, BT-474 and MB-468 cells. LAQ824 also dose- and time-dependently inhibits the growth of multiple myeloma cells.
