Protein Arginine Deiminase

Peptidylarginine Deiminase

Protein arginine deiminase (PAD), is a group of calcium-dependent enzymes, which play crucial roles in citrullination, and can catalyze arginine residues into citrulline. his chemical reaction induces citrullinated proteins formation with altered structure and function, leading to numerous pathological diseases, including inflammation and autoimmune diseases. These pathologies established the PADs as therapeutic targets and multiple PAD inhibitors are known.

Humans encode five PADs, designated PADs 1-4 and PAD6. Of the five PAD isozymes (PAD1, 2, 3, 4 and 6), only four (PADs1-4) are catalytically active. PAD activity is tightly regulated by Ca2+ and PADs contain 4 (PAD1), 5 (PAD3, 4) or 6 (PAD2) Ca2+-binding sites. Dysregulated PAD activity, most notably PAD2 and PAD4, is associated with multiple inflammatory diseases (e.g., rheumatoid arthritis) as well as cancer, and PAD inhibitors, such as Cl-amidine and BB-Cl-amidine, show efficacy in multiple preclinical animal models of disease.

Cat. No. Product Name Effect Purity Chemical Structure
  • HY-100574
    Cl-amidine
    Inhibitor
    Cl-amidine 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 induces apoptosis in cancer cells. Cl-amidine induces microRNA (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.

  • HY-157157
    PAD4-IN-3
    Inhibitor
    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.
