BB-Cl-Amidine is a peptidylarginine deminase (PAD) inhibitor.
Streptonigrin (Bruneomycin), a natural product produced by Streptomyces flocculus, possesses both anti-tumor and anti-bacterial activity. Streptonigrin acts as a pan-PAD inhibitor with IC50s of 48.3±34.2 µM, 26.1±0.3 µM, 0.43±0.03 µM, and 2.5±0.4 µM for PAD1, PAD2, PAD3, and PAD4, respectively[1].
JBI-589 is a non-covalent PAD4 isoform-selective inhibitor. JBI-589 reduces CXCR2 expression and blocks neutrophil chemotaxis. JBI-589 reduces primary tumor and metastases, and enhances the anti-tumor effect of checkpoint inhibitors[1].
Cl-amidine (hydrochloride) is a peptidylarginine deminase (PAD) inhibitor, with an IC50 5.9 μM for PAD4.
GSK-199 hydrochloride is a potent, highly selective and reversible protein arginine deiminase PAD4 inhibitor with IC50 of 250 nM in FP binding assay (0.2 mM Ca), 200 nM in PAD4 NH3 release inhibition assay; shows high specificity for PAD4 over PAD1/2/3/6; affects cellular citrullination and mimic the deficiency in NET production in mice; significantly decreases in complement C3 deposition in both synovium and cartilage in mice.
PAD2-IN-1, a benzimidazole-based derivative, is a potent and selective protein arginine deiminase 2 (PAD2) inhibitor. PAD2-IN-1 shows superior selectivity for PAD2 over PAD4 (95-fold) and PAD3 (79-fold)[1].
YW3-56 is a potent peptidylarginine deiminase (PAD) inhibitor, with an IC50 of 1-5 μM for PAD4.
Cl-amidine is a peptidylarginine deminase (PAD) inhibitor, with an IC50 5.9 μM for PAD4.
PAD4-IN-2 (compound 5i) is a PAD4 inhibitor (IC50=1.94 μM). PAD4-IN-2 inhibits tumor growth in mice by specifically inhibiting the PAD4-H3cit-NETs pathway in neutrophils[1].
Cl-amidine TFA 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 TFA induces apoptosis in cancer cells. Cl-amidine TFA induces microRNA (miR)-16 expression and causes cell cycle arrest. Cl-Amidine TFA prevents histone 3 citrullination and neutrophil extracellular trap formation, and improves survival in a murine sepsis model[1][2][3][4][5].
PAD4-IN-3 (compound 4B) is a PAD4 inhibitor with antitumor activity in vitro and in vivo. PAD4-IN-3 was covalently linked to RGD sequence peptide-modified chitosan (K-CRGDV), resulting in an enhanced oxidative stress-responsive nanoagent. K-CRGDV-PAD4-IN-3 can actively target tumors, inhibit PAD4 activity, block the formation of neutrophil extracellular traps (NETs), and improve the tumor immune microenvironment in response to the tumor microenvironment[1].
GSK484 is a peptidylarginine deiminase 4 (PAD4) inhibitor. GSK484 demonstrates high affinity binding to PAD4 with IC50s of 50 nM in the absence of Calcium. In the presence of 2 mM Calcium, notably lower potency (250 nM) is observed.
PAD-IN-2 is a potent pad4 inhibitor (IC50: <1 μM). PAD-IN-2 can be used in the research of auto-immune diseases and cancers, such as rheumatoid arthritis, vasculitis, systemic lupus erythematosis, cutaneous lupus erythematosis, ulcerative colitis, cystic fibrosis, asthma, multiple sclerosis and psoriasis[1].
GSK106 is an inactive control for the selective PAD4 inhibitors, GSK484 and GSK199[1].
GSK-121 Trifluoroacetates a selective PAD4 inhibitor[1].
PAD2-IN-2 is a potent PAD2 inhibitor. PAD2-IN-2 enters the HEK293T/PAD2 cells with an EC50 of 5.9 μM. PAD2-IN-2 inhibits histone H3 citrullination with an EC50 of 2.1 μM in HEK293/PAD2 cells. PAD2-IN-2 can be used for the research of cancer[1].
D-Cl-amidine is a potent and highly selective PAD1 inhibitor. D-Cl-amidine is well-torelated with no significant toxicity[1].
