Mini-Spotlight: Camostat mesilate, seen to block SARS-CoV-2 entry into human cells

We are pleased to introduce a new serine protease inhibitor, Camostat mesilate (ISP-3606-PI) for research use.

Currently, camostat mesylate (or mesilate) is clinically approved in Japan as a serine protease type II transmembrane serine protease (TMPRSS2) inhibitor for the treatment of pancreatitis. TMPRSS2 is also required for viral spike protein (S Protein) priming, allowing viruses, such as coronaviruses, to enter into cells.  As an inhibitor of TMPRSS2, it subsequently blocks viral lung cell entry.  According to researchers in Japan, it was seen to block SARS-CoV-2 entry into human cells.1,2 Additionally, camostat mesilate is helpful in treating cystic fibrosis by blocking prostasin, a serine protease responsible for sodium channel activity, by reducing sodium transport. Prostasin inhibition also plays a useful role in reducing blood pressure and renal damage in sodium-sensitive hypertension.3,4

"The phospho-NL-4 Ab is fantastic, so that is great news! We have a VERY exciting study ongoing with it.
Not sure if you saw but the original phospho NL-1 Ab you guys made for us we just published in Nature Neuroscience. Thanks for making great antibodies, and we look forward to keep working with you guys!"
