Biological Activity

Description

Cl-amidine is an irreversible pan-peptidylarginine deiminase (PAD) inhibitor with IC50 values of 5.9 ± 0.3 μM, 0.8 ± 0.3 μM, 6.2 ± 1.0 μM for PAD4, PAD1 and PAD3, respectively. Cl-amidine induces apoptosis.

Targets

PAD1 ^[1] (Cell-free assay)	PAD4 ^[1] (Cell-free assay)	PAD3 ^[1] (Cell-free assay)
0.8 μM	5.9 μM	6.2 μM

In vitro

Cl-amidine antagonizes the PAD4-mediated enhancement of the the p300GBD-GRIP1 interaction in a dose-dependent manner. The inhibitory effect of this compound is not a nonspecific one but is targeted at the active PAD4 enzyme^[1]. Cl-amidine increases p53 expression in CD45 positive immune cells. It triggers the differentiation and apoptosis of multiple cancer cell lines that are p53+/+ and p53−/− (e.g., HL60, HT29, TK6, and U2-OS cells). Cl-amidine induces the expression of p53 and several downstream target genes including the cyclin dependent kinase inhibitor p21, GADD45, and the proapoptotic protein PUMA in U2-OS osteosarcoma cells^[2].

In vivo

Cl-amidine treatment inhibits NZM(New Zealand mixed 2328) NET(neutrophil extracellular trap) formation in vivo and significantly alters circulating autoantibody profiles and complement levels while reducing glomerular IgG deposition. Further, Cl-amidine increases the differentiation capacity of bone marrow endothelial progenitor cells, improves endothelium-dependent vasorelaxation, and markedly delays time to arterial thrombosis induced by photochemical injury. Cl-amidine delays thrombosis development in NZM mice. It inhibits PADs in mice without significant toxicity and improves disease phenotypes in animal models of inflammatory arthritis and inflammatory bowel disease^[3]. And It is shown to reduce disease severity in mouse models of ulcerative colitis and RA^[2].

Protocol

Cell Research:

^[1]

- Collapse

Cell lines: CV-1 cells
Concentrations: 0-200 μM
Incubation Time: 40 h
Method:
CV-1 cells are transiently transfected with plasmids encoding a luciferase reporter construct, p300GBD fused to the Gal4 DNA binding domain, the p300 binding domain of GRIP1 (i.e., the AD1 domain) fused to the VP16 activation domain (AD), and either wild-type PAD4 or the catalytically defective C645S mutant. Cl-amidine (0-200 μM) is then added to the cell culture medium and incubated for 40 h. Cell extracts are then prepared, and the luciferase activity present in these extracts is quantified.

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
