Solubility (25°C)*

In vitro

DMSO

58 mg/mL (198.54 mM)

Ethanol

5 mg/mL (17.11 mM)

Water

Insoluble

In vivo (Add solvents to the product individually and in order)

Clear solution

5%DMSO 1 Corn oil

3.0mg/ml

Taking the 1 mL working solution as an example, add 50 μL of 60 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

ITSA-1 (ITSA1) is an HDAC activator via TSA suppression, but shows no activity towards other HDAC inhibitors.

Targets

HDAC ^[1]
(Cell-free assay)

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines A549 cells Concentrations 50 μM Incubation Time 17.5 h Method A549 cells ( 75% confluent) in 10-cm dishes are treated with DMSO (0.1%), TSA (500 nM), or tubacin (2 μM) for 4.5 h, and then either DMSO (0.1%) or ITSA1 (50 μM) is added for an additional 17.5 h. Samples are rinsed in PBS, trypsinized, and fixed for 2 h in 70% ethanol 30% PBS (4°C). Cells then are washed once in PBS and stored overnight in PBS (4°C).
