Camostat mesylate (also known as FOY-305; FOY-S980), the mesylate salt of Camostat, is a potent and orally bioactive trypsin-like protease inhibitor with potential antifibrotic activity. It acts by inhibiting airway epithelial sodium channel (ENaC) function with an IC50 of 50 nM.
| ln Vitro |
Camostat mesylate (Camostat mesilate) suppresses monocyte chemoattractant protein-1 (MCP-1) and TNF-α production by monocytes, as well as PSC proliferation and MCP-1 production [1]. Camostat mesylate is a trypsin-like protease inhibitor that delivers efficacy (IC50=50 nM) and sustained degradation of ENaC function in human airway epithelial cell models that is reversible upon addition of excess trypsin [3].

| ln Vivo |
In a pathogenic mouse model, camostat mesilate (30 mg/kg; oral; twice daily for 9 days) inhibits the development and transmission of SARS-CoV [4].

| Animal Protocol |
Animal/Disease Models: 6-8 week old female balb/c (Bagg ALBino) mouse (lethal SARS-CoV infection model)[4]
Doses: 30 mg/kg Route of Administration: Po; twice a day for 9 days Experimental Results: Effective in protecting mice against death due to a lethal infection by SARS-CoV, with a survival rate of ∼60%. |

| Additional Infomation |
Camostat mesylate is a methanesulfonate (mesylate) salt prepared from equimolar amounts of camostat and methanesulfonic acid. It is a serine protease inhibitor approved and marketed in Japan in 1985 for the alleviation of acute symptoms associated with chronic pancreatitis. In 1994, it was approved for the treatment of postoperative reflux esophagitis. It has a role as an anticoronaviral agent, an anti-inflammatory agent, an antifibrinolytic drug, an antihypertensive agent, an antineoplastic agent, an antiviral agent and a serine protease inhibitor. It contains a camostat(1+).
Camostat Mesylate is the mesylate salt form of camostat, an orally bioavailable, synthetic serine protease inhibitor, with anti-inflammatory, antifibrotic, and potential antiviral activities. Upon oral administration, camostat and its metabolite 4-(4-guanidinobenzoyloxyl)phenyl acetic acid (FOY 251) inhibit the activities of a variety of proteases, including trypsin, kallikrein, thrombin and plasmin, and C1r- and C1 esterases. Although the mechanism of action of camostat is not fully understood, trypsinogen activation in the pancreas is known to be a trigger reaction in the development of pancreatitis. Camostat blocks the activation of trypsinogen to trypsin and the inflammatory cascade that follows. Camostat may also suppress the expression of the cytokines interleukin-1beta (IL-1b), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-a) and transforming growth factor-beta (TGF-beta), along with alpha-smooth muscle actin (alpha-SMA). This reduces inflammation and fibrosis of the pancreas. In addition, camostat may inhibit the activity of transmembrane protease, serine 2 (TMPRSS2), a host cell serine protease that mediates viral cell entry for influenza virus and coronavirus, thereby inhibiting viral infection and replication. |

Solubility in Formulation 1: ≥ 2.08 mg/mL (4.21 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 20.8 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: ≥ 2.08 mg/mL (4.21 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 20.8 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

*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.
