生物活性

製品説明 PCI-34051 is a potent and specific HDAC8 inhibitor with IC50 of 10 nM in a cell-free assay. It has greater than 200-fold selectivity over HDAC1 and 6, more than 1000-fold selectivity over HDAC2, 3, and 10. PCI-34051 induces caspase-dependent apoptosis.
in vitro

PCI-34051 possesses promising potency for HDAC8 with a Ki of 10 nM. This compound has high selectivity (approximately fivefold) for HDAC8 relative to the other class I HDACs including HDAC1. It reveals greater than 200-fold selectivity over HDAC1 and HDAC6, and greater than 1000-fold selectivity over HDAC2, HDAC3 and HDAC10. This chemical inhibits ovarian tumor line OVCAR-3 with a GI50 of 6 μM and 15% cell death. Neither significant tubulin nor histone acetylation is observed in the sensitive cell lines treated with this compound at concentrations less than 25 μM at 24 hours nor at earlier timepoints. It induces a selective cytotoxic effect in cell lines derived only from T-cell malignancies. This compound induces caspase-dependent apoptosis. When caspase-3 activity is measured at various times after treatment with 5 μM of this chemical, increasing levels of activity are observed from 12 to 24 to 48 hours, another hallmark of apoptosis, consistent with the higher levels of caspase activity at this timepoint. It does not stimulate Bid cleavage, a characteristic effect of the extrinsic apoptotic pathway. While P116 and J.RT3-T.5 are sensitive to this compound, the PLCγ1-deficient J.gamma1 line reveals a marked decrease in the extent of its induced apoptosis. In addition, steady-state calcium levels strongly influence the apoptosis induced by this chemical. It induces cytochrome c release from mitochondria.[1]

キナーゼアッセイ Histone deacetylase activity
For PCI-34051 characterization, measurements are perfomed in a reaction volume of 100 μL using 96-well assay plates in a fluorescence plate reader. For each isozyme. The HDAC protein in reaction buffer (50 mM HEPES, 100 mM KCl, 0.001% Tween-20, 5% dimethyl sulfoxide, pH7.4, supplemented with bovine serum albumin at concentrations of 0-0.05%) is mixed with this compound at various concentrations and allowed to incubate for 15 min. Trysin is added to a final concentration of 50 nM, and acetyl-gly-Ala-(N-acetyl-Lys)-amino-4-methylcoumarin is added to a final concentration of 25-100 μM to initiate the reaction. After a 30 min lag time, the fluorescence is measured over a 30 min time frame using an excitation wavelength of 335 nm and a detection wavelength of 460 nm. The increase in fluorescence wih time is used as the measure of the reaction rate.

実験の流れ

Tumor cell lines and human umbilical vein endothelial cells are cultured for at least two doubling times, and growth is monitored at the end of PCI-34051 exposure using an Alamar Blue fluorometric cell proliferation assay as recommended by the manufacturer. This compound is assayed in triplicate wells in 96-well plates. The concentration required to inhibit cell growth by 50% (GI50) and 95% confidence intervals are estimated from nonlinear regression using a four-parameter logistic equation.
