生物活性

Cl-amidine hydrochloride 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 hydrochloride induces apoptosis in cancer cells. Cl-amidine hydrochloride induces microRNA (miR)-16 (miRNA-16, microRNA-16) expression and causes cell cycle arrest. Cl-Amidine hydrochloride prevents histone 3 citrullination and neutrophil extracellular trap formation, and improves survival in a murine sepsis model.

体外研究

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).
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 prevents histone 3 citrullination and neutrophil extracellular trap formation, and improves survival in a murine sepsis model.

Apoptosis Analysis.

Cell Line: TK6 lymphoblastoid cells and HT29 colon cancer cells.
Concentration: 0, 5, 10, 15, 20, 25, 50 μg/mL.
Incubation Time: 24 h.
Result: Induced apoptosis dose-dependently.
体内研究

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.
