Biological Activity

Description CAY10603 (BML-281) is a potent and selective HDAC6 inhibitor with IC50 of 2 pM, >200-fold selectivity over other HDACs.
Targets
HDAC6 [1]
(Cell-free assay)
2 pM
In vitro
In vitro CAY10603, via inhibition of HDAC6, shows potent antiproliferative activity against pancreatic cancer cell lines with IC50 of <1 μM, which can be used as a new molecular probe in exploring HDAC biology. [1]
Kinase Assay HDAC Inhibition Assays
Purified HDACs are incubated with 1 mM carboxyfluorescein (FAM)-labeled acetylated peptide substrate and test compound for 17 h at 25 °C in HDAC assay buffer containing 100 mM HEPES (pH 7.5), 25 mM KCl, 0.1% BSA, and 0.01% Triton X-100. Reactions are terminated by the addition of buffer containing 0.078% SDS for a final SDS concentration of 0.05%. Substrate and product are separated electrophoretically using a Caliper LabChip 3000 system with blue laser excitation and green fluorescence detection (CCD2). The fluorescence intensity in the substrate and product peaks is determined using the Well Analyzer software on the Caliper system. The reactions are performed in duplicate for each sample. IC50 values are automatically calculated using the IDBS XLFit version 4.2.1 plug-in for Microsoft Excel and the XLFit 4-Parameter Logistic Model: ((A+((B_A)/1+((C/x)D)))), in which x is compound concentration, A and B are respectively the estimated minimum and maximum of percent inhibition, C is the inflection point, and D is the Hill slope of the sigmoidal curve. The standard errors of the IC50 values are automatically calculated using the IDBS XLFit version 4.2.1 plug-in for Microsoft Excel and the formula xf4_FitResultStdError.
Cell Research Cell lines BxPc-3, HupT3, Mia Paca-2, Panc 04.03, and SU 86.86 cells
Concentrations ~50 μM
Incubation Time 72 hours
Method The pancreatic cancer cell lines BxPc-3, HupT3, Mia Paca-2, Panc 04.03, and SU 86.86 are grown in medium (DMEM or RPMI) containing 10% fetal calf serum and l-glutamine. Pancreatic cancer cells are plated out in duplicate into 6 wells of a 96-well microtiter plate. Four hours post plating, individual wells are treated with diluent (DMSO) or varying concentrations of SAHA or the indicated HDACIs from a concentration of 1 nM to 50 mM. Cytotoxicity is measured at time “0”, and 72 h post treatment using the colorimetric MTT assay according to the manufacturer’s suggestions. The IC50 values are calculated using XLfit.

Frequently Asked Questions

Question 1:
I want to use CAY10603 and Tubastatin A via IP for mice. What can serve as the working solution instead of DMSO?

Answer:
S7596 CAY10603 can be dissolved in 5% DMSO+50% PEG 300+ddH2O at 9mg/ml as a clear solution. The dissolving protocol is the same as S8049.
