| 生物活性 |
Cl-amidine TFA is an orally active peptidylarginine deminase (PAD) inhibitor, with IC50 values of 0.8 μM, 6.2 μM and 5.9 μM for PAD1, PAD3, and PAD4, respectively. Cl-amidine TFA induces apoptosis in cancer cells. Cl-amidine TFA induces microRNA (miR)-16 (miRNA-16, microRNA-16) expression and causes cell cycle arrest. Cl-Amidine TFA prevents histone 3 citrullination and neutrophil extracellular trap formation, and improves survival in a murine sepsis model[1][2][3][4][5].

IC50 & Target |
IC50: 0.8 μM (PAD1), 5.9 μM (PAD4), 6.2 μM (PAD3)[1][5].

体外研究
(In Vitro) |
Cl-amidine is a bioavailable haloacetamidine-based compound that inhibits all the active PAD isozymes with near equal potency (kinact/KI=13,000 M-1•min-1 for PAD4)[1].
Cl-amidine (0, 5, 10, 15, 20, 25, 50 μg/mL, 24 hours) induces apoptosis in TK6 lymphoblastoid cells and HT29 colon cancer cells in a dose-dependent manner. Interestingly, the colon cancer cell line (HT29) is relatively resistant to apoptosis caused by Cl-amidine[2].
Cl-amidine irreversibly inactivates PADs by covalently modifying an active site cysteine that is important for its catalytic activity[4].
