MS436 (MS-346), a diazobenzene analog, is a novel, potent and selective inhibitor of BET/BRD4 bromodomain with potential anti-inflammatory activity. It inhibits BRD4 (1) and BRD4 (2) with Ki values of <0.085 μM and 0.34 μM, respectively. MS 436 effectively inhibits NF-κB-directed production of nitric oxide/NO and proinflammatory cytokine interleukin-6 (IL-6) in murine macrophages.
| ln Vitro |
MS436, through a sequence of water-mediated interactions, has low nanomolar affinity (estimated Ki of 30-50 nM) with preference for the first bromodomain over the second. MS436 efficiently suppresses BRD4 activity in NF-κB-directed generation of NO and pro -inflammatory cytokine interleukin-6 in murine macrophages. MS436 represents a novel class of bromodomain inhibitors and will permit further exploration of the biological functions of the two bromodomains of BRD4 in gene expression. MS436 demonstrates high affinity with an estimated Ki=30-50 nM for the BRD4 BrD1 and a 10-fold selectivity over the BrD2, which is achieved by a unique series of water-mediated intermolecular interactions[1].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 1 mg/mL (2.61 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.0 mg/mL clear DMSO stock solution to 400 μL of PEG300 and mix evenly; then add 50 μL of Tween-80 to the above solution and mix evenly; then add 450 μL of 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. Solubility in Formulation 2: ≥ 1 mg/mL (2.61 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

| 5 mM | 0.5216 mL | 2.6081 mL | 5.2162 mL | |
| 10 mM | 0.2608 mL | 1.3041 mL | 2.6081 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.
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.
