IC50: 0.8 μM (PAD1), 5.9 μM (PAD4), 6.2 μM (PAD3).
Cl-amidine is a bioavailable haloacetamidine-based compound that inhibits all the active PAD isozymes with near equal potency (k

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.
Cl-amidine irreversibly inactivates PADs by covalently modifying an active site cysteine that is important for its catalytic activity.
Apoptosis Analysis.

Concentration: | 0, 5, 10, 15, 20, 25, 50 μg/mL. |

Cl-amidine (75 mg/kg, ip once daily) suppresses and treats DSS-induced colitis in mice.
Cl-amidine (5, 25, 75 mg/kg, oral gavage, once daily) leads to significant reductions in the histology scores dose-dependently.
