| | BB-Cl-Amidine Usage And Synthesis |
| Description | BB-Cl-Amidine is a modified version of Cl-amidine that retains the functional components but possesses a C-terminal benzimidazole group designed to limit proteolysis of the C-terminal amide. BB-Cl-Amidine irreversibly inactivates all four PAD subtypes (kinact/KI = 16,100, 4,100, 6,800, and 13,300 M-1min-1 for PAD1-4, respectively) by covalently modifying an active site cysteine that is important for its catalytic activity. The cellular potency of BB-Cl-amidine against PAD4 is increased 20-fold over the parent compound (EC50 = 8.8 μM versus >200 μM for Cl-amidine). BB-Cl-Amidine also has a significantly longer in vivo half-life than Cl-amidine (1.75 h versus ~15 min, respectively). Both compounds inhibit the formation of neutrophil extracellular traps without altering H2O2 production by neutrophils. BB-Cl-Amidine is effective in vivo, improving endothelial function while downregulating the expression of type I interferon-regulated genes in MRL/lpr mice. | | Uses | BB-Cl-Amidine is a peptidylarginine deminase (PAD) inhibitor. | | in vivo | Treatment with BB-Cl-amidine subtly reduces splenomegaly in MRL/lpr mice, while there is a trend towards increased circulating levels of anti-NET antibodies with PAD inhibitor treatment. However, neither PAD inhibitor affected body weight or total IgG levels. Indeed, treatment with both Cl-amidine and BB-Cl-amidine significantly improves endothelium-dependent vasorelaxation. The BB-Cl-amidine group also shows a strong trend towards downregulation of IRGs. Treatment with either Cl-amidine or BB-Cl-amidine significantly improves muzzle alopecia, in many cases preventing it entirely[1]. | Animal Model: | MRL/lpr mice[1].
| | Dosage: | 1 mg/kg. | | Administration: | Subcutaneous injection daily from 8 to 14 weeks of age. | | Result: | Significantly improved endothelium-dependent vasorelaxation and showed a strong trend towards downregulation of IRGs. |
