NCGC-00244536 HCl (KDM4B Inhibitor B3 HCl; KDM4B-IN-B3) is a novel and potent inhibitor of the Histone lysine demethylase KDM4 with an IC50 of 10 nM.
ln Vitro |
NCGC00244536 exhibits over 100-fold selectivity against immortalized epithelial cell lines PrEC1 and PrEC4, and high sensitivity (IC50=40 nM) against rapidly proliferating AR-negative PC3 cells. NCGC00244536 inhibits androgen-stimulated LNCaP cell growth and efficiently blocks AR cell lines, including VCaP and LNCaP, with an IC50 in the submicromolar range. With a micromolar IC50, NCGC00244536 also successfully suppresses the growth of various cancer cell lines, such as the MDA-MB2 and MCF-7 breast cancer cell lines[1].

ln Vivo |
In addition to showing no substantial harm and appearing normal, treatment with NCGC00244536 greatly slowed the growth of the tumors in the animals. The highly cellular, distinct, and fibrotic tumors treated with NCGC00244536 were clearly shown by histological data [1].

Solubility (In Vivo) |
Solubility in Formulation 1: 2.75 mg/mL (7.19 mM) in 10% DMSO + 40% PEG300 +5% Tween-80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 27.5 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 + to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.  (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
