Description HPOB is an effective and specific HDAC6 inhibitor (IC50: 56 nM), >30-fold selectivity over other HDACs.
Targets&IC50 HDAC6:56 nM
In vitro In mice bearing CWR22 human prostate cancer xenografts, the combination of HPOB (300 mg/kg/day) with SAHA significantly inhibits the growth of pre-existing tumors, whereas the use of either compound alone does not exhibit a noticeable inhibitory effect.
In vivo In HFS cells, HPOB enhances transformation cell death induced by Etoposide, Doxorubicin, or SAHA. HPOB also augments Etoposide-induced transformation cell death in transformed cells via the apoptosis pathway. In both normal (HFS) and transformed (LNCaP, A549, and U87) cells, HPOB induces α-tubulin proteins without affecting histones, inhibiting cell growth without impacting cell viability.
Kinase Assay In Vitro Enzymatic Assay for Histone Deacetylases: In vitro activities of the 11 recombinant human zinc-dependent HDAC enzymes are detected by ?uorigenic release of 7-amino-4-methylcoumarin from substrate upon deacetylase enzymatic activity. A series of dilutions of the unique HDAC6 compound, tubacin, and SAHA are prepared with 10% DMSO in HDAC assay buffer, and 5 μL of the dilution was added to a 50-μL reaction so that the ?nal concentration of DMSO is 1% in all of the reactions. The enzymatic reactions are conducted in duplicate at 37 °C for 30 min in a 50-μL mixture containing HDAC assay buffer, 5 μg BSA, an HDAC substrate, an HDAC enzyme, and a test compound. After enzymatic reactions, 50 μL of 2× HDAC developer is added to each well, and the plate is incubated at room temperature for an additional 15 min. Fluorescence intensity is measured at an excitation of 360 nm and an emission of 460 nm using a Synergy microplate reader. Negative (no enzyme, no inhibitor, a drug with no HDAC inhibition activity) and positive controls (known HDAC inhibitor SAHA) are included in the assays. IC50 is determined at the drug concentration that results in 50% reduction of HDAC activity compared with the control.
Cell Research Normal (HFS) and transformed (LNCaP, A549, and U87) cells are cultured with indicated doses of HPOB for 72 h. Five micromolars SAHA is a positive control.Graphs were constructed using Prism 5. (Only for Reference)

Molarity Calculator allows you to calculate the

  • Mass of a compound required to prepare a solution of known volume and concentration
  • Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Concentration of a solution resulting from a known mass of compound in a specific volume
See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
