Description

Biochem/physiol Actions

Trypsin-like serine protease inhibitor Camostat (FOY-305) active metabolite with inhibitory potency against transmembrane serine protease 2 (TMPRSS2).



FOY-251 is a trypsin-like serine protease inhibitor and an active metabolite of the oral drug Camostat/FOY-305 (trypsin IC50 = 51/55 nM by FOY-305/FOY-251; plasma kallikrein/plasmin IC50 = 1.48/2.64 μM by FOY-305 and 2.32/12.5 μM by FOY-251). FOY-251 and FOY-305 are also potent inhibitor against transmembrane serine protease 2 (TMPRSS2 IC50 = 6.2/33.3 nM by by FOY-305/FOY-251) that primes SARS-CoV-2 spike protein for host cell entry.
