4-Methylumbelliferone (Hymecromone; 4-MU) is a potent and selective inhibitor of hyaluronic acid (HA) biosynthesis with an IC50 of 0.4 mM. The activation of HAS2 and the over-production of HA are existed in many metastatic tumor cell lines. Increased synthesis of HA is often associated with increased metastatic potential and invasivity in tumor cells. 4-Methylumbelliferone (MU), an inhibitor of HA synthesis, has been studied as a potential anti-tumor drug on account of inhibiting the growth of primary tumors and distant metastasis of tumor cells.

4-Methylumbelliferone (4-MU) has an impact on a number of crucial angiogenesis processes, such as adhesion, tube formation, proliferation of endothelial cells, and extracellular matrix remodeling. In the proliferation assay, the half-maximal inhibitory concentration (IC50) values for RF-24 endothelial cells and human microvascular endothelial cells were 0.37±0.03 mM and 0.65±0.04 mM, respectively. One-third of HMEC and five percent of RF-24 cells underwent apoptosis after receiving a 24-hour treatment with 2-methylumbellarone (2 mM). One hour of treatment with 1 mM 4-Methylumbelliferone resulted in a reduction of adherent endothelial cells of over 20%. In the tube formation assay, the minimal inhibitory doses for HMEC and RF-24 were 2 and 0.5 mM 4-Methylumbelliferone, respectively. Two endothelial cell lines were investigated, and after treatment with 4-Methylumbelliferone, the expression of matrix metalloproteinase 2 changed in various ways [1].

Solubility in Formulation 1: ≥ 2.5 mg/mL (14.19 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 25.0 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. Solubility in Formulation 2: ≥ 2.5 mg/mL (14.19 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 25.0 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. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (14.19 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. Solubility in Formulation 4: 50 mg/mL (283.82 mM) in 50% PEG300 50% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. |

*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.

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.
