peptidylarginine deiminase

GSK484 hydrochloride (GTPL8577) is a reversible peptidyl-arginine deiminase 4 (PAD4) inhibitor. It binds to PAD4 with high affinity, with IC50 of 250 and 50 nM in the presence and absence of 2 mM calcium, respectively. GSK484 promotes the radiosensitivity of colorectal cancer (CRC) and inhibits NET formation in vitro and in vivo.

Acefylline (Theophylline-7-acetic acid), a stimulant drug of the xanthine chemical class, acts as an adenosine receptor antagonist. It is combined with diphenhydramine in the pharmaceutical preparation Etanautine to help offset its stimulant effects

GSK199 is a selective PAD4 inhibitor(IC50 of 200 nM in the absence of calcium).

Cl-amidine hydrochloride is an orally available PAD inhibitor that blocks histone 3 deimination and neutrophil extracellular trap formation and improves survival in septic mice. It induces apoptosis in cancer cells and induces miR-16 to cause cell cycle arrest.

BMS-P5 is a specific and orally active Peptidylarginine Deiminase 4 (PAD4) inhibitor.

BMS-P5 free base is a specific and orally active peptidylarginine deiminase 4 (PAD4) inhibitor that blocks the formation of Neutrophil Extracellular Traps and delays the progression of multiple myeloma. Administration of BMS-P5 to multiple myeloma-bearing mice delays symptom onset and disease progression. Targeting PAD4 may be beneficial for treating multiple myeloma.

GSK121 is an inhibitor of selective PAD4.

Peptidyl Arginine Deiminase, Rabbit (EC 3.5.3.15) is an enzyme that catalyzes the conversion of arginine to citrulline. Calcium ions are necessary for the activity of Peptidyl Arginine Deiminase.

BB-Cl-Amidine (TFA) is an inhibitor of peptidylarginine deiminase (PAD).

PAD-IN-3 (Compound 16) is a potent dual inhibitor of peptidylarginine deiminase 4 (PAD4) and PAD1, with IC50 values of 0.204 μM and 0.273 μM, respectively. It has potential applications in the research of citrullination-related diseases such as cancer and autoimmune disorders.

YW3-56 is a potent peptidylarginine deiminase (PAD) inhibitor, with an IC50 of 1-5 μM for PAD4. Compared with Cl-amidine, YW3-56 shows >60-fold increase in cell growth inhibition efficacy (IC50 about 2.5 μM) but only 5-fold increase in PAD4 inhibition (IC sub>50 about 1-5 μM). At 2-4 μM concentrations, YW3-56 displays mainly cytostatic effects by slowing cell division, whereas at higher concentrations, it exerts cytotoxic effects by altering cell morphology and killing cells[1].

YW3-56 is an inhibitor of protein arginine deiminase 2 (PAD2) and PAD4 (IC50s = 0.5-1 and 1-5 μM, respectively).1It inhibits the growth of U2OS osteosarcoma cells (IC50= ~2.5 μM) in a p53-dependent mannerviainduction of SESN2 and subsequent inhibition of mTORC1. YW3-56 (10 mg/kg) reduces tumor growth in an S-180 murine sarcoma tumor model. It also inhibits tumor growth in the 1883 MDA-MB-231 breast cancer bone metastasis mouse xenograft model.2 1.Wang, Y., Li, P., Wang, S., et al.Anticancer peptidylarginine deiminase (PAD) inhibitors regulate the autophagy flux and the mammalian target of rapamycin complex 1 activityThe Journal of Biological Chemisty287(31)25941-25952(2012) 2.Wang, S., Chen, X.A., Hu, J., et al.ATF4 gene network mediates cellular response to the anticancer PAD inhibitor YW3-56 in triple-negative breast cancer cellsMol.
