Purinostat mesylate, the mesylate salt of Purinostat, is an inhibitor of class I and class IIb HDACs with IC50s from 0.81 to 11.5 nM. It exhibits anticancer activity by inducing apoptosis and affecting cell cycle of LAMA84 and 188 BL-2 cells.
| ln Vitro |
Inhibiting HDAC1, 2, 3, and 8 with IC50s of 0.81, 1.4, 1.7, and 3.8 nM, HDAC6 and 10 with IC50s of 11.5 and 1.1 nM, and HDAC4, 5, 7, 9, and 11 with IC50s of 1072, 426, 690, 622, and 3348 nM, respectively, are all possible with purinostat mesylate (1–10 μM)[1]. Purinostat mesylate (zero to sixty nanometers; 24 hours) alters the cell cycle and causes apoptosis in LAMA84 and 188 BL-2 cells[1].

| ln Vivo |
Purinostat mesylate (5–10 mg/kg; intraperitoneally three times a week for five weeks) efficiently inhibits the growth of leukemia in vivo[1]. In BCR-ABL(T315I)-induced primary B-ALL mice, purinostat mesylate (5–10 mg/kg; intravenously three times a week for eight weeks) exhibits strong anti-leukemia effects[1].

| Additional Infomation |
Purinostat Mesylate is the mesylate salt form of purinostat, an inhibitor of histone deacetylase (HDAC) classes I and IIb, with potential antineoplastic activities. Upon administration, purinostat selectively inhibits the catalytic activity of class I and IIb HDACs, which results in an accumulation of highly acetylated chromatin histones, the induction of chromatin remodeling and an altered pattern of gene expression. This leads to the inhibition of tumor oncogene transcription, and the selective transcription of tumor suppressor genes, which inhibits tumor cell division and induces tumor cell apoptosis. HDAC, an enzyme upregulated in many tumor types, deacetylates chromatin histone proteins. Class I HDACs are located in the nucleus and include HDACs 1, 2, 3, and 8; class IIb HDACs include HDAC 6 and 10 and are located in both the nucleus and the cytoplasm.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 1.7047 mL | 8.5234 mL | 17.0468 mL | |
| 5 mM | 0.3409 mL | 1.7047 mL | 3.4094 mL | |
| 10 mM | 0.1705 mL | 0.8523 mL | 1.7047 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
