AR-42 (also known as OSU-HDAC42), a derivative of hydroxamate-tethered phenylbutyrate, is a novel and potent inhibitor of histone deacetylase (HDAC) that potently inhibits the activity of HDAC with 50% inhibition concentration IC50 value of 16 nM and induces histone H3 acetylation, α-tubulin acetylation and p21 up-regulation, which have been considered as the hallmark indicators of HDAC inhibition. AR-42 has been found to modulate several apoptosis inhibitors as well as cell survival regulator, including Akt, Bcl-xL, Bax, Ku70 and surviving, and exert potent antitumor activity against multiple tumor types, such as human prostate and hepatic cancers, at least partially through PI3K/Akt pathway inhibition.

| Kinase experiment [1]: | |
|
In vitro HDAC assay |
HDAC activity was analyzed by using an HDAC assay kit. This assay was based on the ability of DU-145 nuclear extract, which is rich in HDAC activity, to mediate the deacetylation of the biotinylated [3H]-acetyl histone H4 peptide that was bound to streptavidin agarose beads. The release of [3H]-acetate into the supernatant was measured to calculate the HDAC activity. Sodium butyrate (0.25 ~ 1 mM) was used as a positive control. |
| Cell experiment [1]: | |
|
Cell lines |
DU-145 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 |
10 ~ 1000 nM; 96 hrs |
|
Applications |
AR-42 inhibited the growth of DU-145 cells with an IC50 value of 0.11 μM. |
| Animal experiment [2]: | |
|
Animal models |
Intact male NCr athymic nude mice inoculated s.c. with PC-3 cells |
|
Dosage form |
25 mg/kg, q.d., or 50 mg/kg, q.o.d.; p.o.; for 28 days |
|
Applications |
At the doses of 25 mg and 50 mg, AR-42 inhibited the growth of PC-3 tumor xenografts by 52% and 67%, respectively. |
|
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. |
