Description

Pivanex (AN-9), a derivative of Butyric acid, is an HDAC inhibitor with antimetastic and antiangiogenic properties. Pivanex down-regulates bcr-abl protein and enhances apoptosis[1].

In Vitro

Pivanex (100-500 μM) exhibits significant anti-proliferation activity in K562 cells[1].
Pivanex (100-500 μM) also enhances apoptosis and caspase activity in K562 cells[1].
Pivanex (200 μM) induces enhancement in the G2-M phase, a moderate enhancement in the S phase and a slight reduction in G0-G1 of the cell cycle[1].
Pivanex (AN-9) has selective toxicity to acute leukemia and drug-resistant primary leukemia and cancer cell lines[2].

Cell Viability Assay[1]

Cell Line: K562 cells.
Concentration: 100-500 μM.
Incubation Time: 24 hours.
Result: Reduced the number of K562 viable cells significantly.
100 μM Pivanex with 0.125 or 0.25 μM STI571 reduced the number of viable cells synergistically.

Apoptosis Analysis[1]

Cell Line: K562 cells.
Concentration: 100-500 μM.
Incubation Time: 6-72 hours.
Result: Increased the number of K562 apoptotic cells significantly.
Increased the caspase activity in K562 cells significantly after only 4 h of incubation with 500 μM.
In Vivo

Pivanex (AN9, 200 mg/kg, b.i.d, daily) significantly improves the survival of SMN7 SMA mice. AN9 treatment also marked delays the end stage of disease as defined by the onset of body mass loss[3].

Animal Model: SMN7 SMA mice (SMN2+/+; SMN7+/+; mSmn−/−)[3].
Dosage: 200 mg/kg.
Administration: Oral administration, b.i.d, at 09.00 and 17.00 daily.
Result: Improved the mean lifespan of treated SMN7 SMA mice by 84.6%.
Delayed the onset of body mass loss in SMN7 SMA mice by 94.9%.
