| 生物活性 | Cl-amidine is an orally activepeptidylarginine deminase (PAD)inhibitor, withIC50values of 0.8 μM, 6.2 μM and 5.9 μM for PAD1, PAD3, and PAD4, respectively. Cl-amidine inducesapoptosisincancercells. Cl-amidine inducesmicroRNA(miR)-16 (miRNA-16, microRNA-16) expression and causes cell cycle arrest. Cl-Amidine 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-1omin-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].
Apoptosis Analysis[2]. | 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
(In Vivo) | Cl-amidine (75 mg/kg, ip once daily) suppresses and treats DSS-induced colitis in mice[2].
Cl-amidine (5, 25, 75 mg/kg, oral gavage, once daily) leads to significant reductions in the histology scores dose-dependently[2].
| Animal Model: | C57BL/6 mice (8-12 wk old, DSS mouse model of colitis)[2]. | | Dosage: | 75 mg/kg. | | Administration: | IP once daily. | | Result: | Suppressed PAD activity, protein citrullination, and PAD levels in the colon in vivo. |
| Animal Model: | C57BL/6 mice (8-12 wk old, DSS mouse model of colitis)[2]. | | Dosage: | 5, 25, 75 mg/kg. | | Administration: | Oral gavage once daily. | | Result: | Led to significant reductions in the histology scores. |
