Cl-amidine (hydrochloride) is a peptidylarginine deminase (PAD) inhibitor, with an IC50 5.9 μM for PAD4.
Cl-amidine is a peptidylarginine deminase (PAD) inhibitor, with an IC50 of 5.9±0.3 μM for PAD4 and 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 induces apoptosis (identified as annexin V-positive/propidium iodide-negative cells) in such cells in a dose-dependent manner, indicating that Cl-amidine induces apoptosis of WBCs in vitro. Interestingly, the colon cancer cell line (HT29) is relatively resistant to apoptosis caused by Cl-amidine[2].
Significantly higher levels of colon inflammation in the 2% DSS than the 2% DSS+Cl-amidine mice are showed. The mean histology scores are 24.2±1.7 (SE) and 13.9±1.6, respectively. Most of the damage in the DSS-only group is in the distal colon, and this damage is suppressed with DSS+Cl-amidine. For the DSS-treated group, the mean colon length is 7.2±0.2 cm. In contrast, the average colon length of the DSS+Cl-amidine group is 8.4±0.2 cm, which is comparable to the mean colon lengths obtained for the wateralone and water+Cl-amidine groups (8.4±0.3 and 7.9±0.2 cm, respectively). The total distance and average speed of mice over a 96-h period are also measured. The results of these analyses demonstrate that the total distance is 5,072±381 and 3,190±401 m for the water-treated and DSS+Cl-amidine mice, but only 800±163 m for the DSS-only group. Similarly, the average speed on the wheel over the 4-day period is 6.2±0.63 and 5.3±0.58 m/min for the water-treated and DSS+Cl-amidine groups, but only 1.8±0.51 m/min for the DSS group[2].
