GSK484 hydrochloride

CAS No. : 1652591-81-5

MCE 站：GSK484 hydrochloride

产品活性：GSK484 hydrochloride 是一种有效且可逆的肽酰基精氨酸脱亚氨酶 4 (PAD4) 抑制剂。GSK484 hydrochloride 高亲和力与 PAD4 结合，在不存在钙的情况下 IC₅₀ 为 50 nM。在 2 mM 钙的存在下，IC₅₀ 为 250 nM。

研究领域：Epigenetics

作用靶点：Protein Arginine Deiminase

In Vitro: GSK484 demonstrates high affinity binding to the low-calcium form of PAD4 with IC₅₀s of 50 nM and 250 nM in the absence of Calcium (0 mM) and Calcium (2 mM), respectively. GSK484 also inhibits PAD4 citrullination (at 0.2 mM Calcium) of benzoyl-arginine ethyl ester (BAEE) substrate in a concentration-dependent manner, as detected using an NH₃ release assay.

In Vivo: To address whether PAD4 inhibition can suppress cancer-associated kidney injury, MMTV-PyMT mice are treated with the PAD4 inhibitor GSK484 at 4 mg/kg daily for one week. This dose suppress the elevated number of neutrophils undergoing NETosis in peripheral blood in mice with cancer. In parallel, the total protein level in urine from MMTV-PyMT mice is significantly reduced compared with untreated tumor-bearing mice, further supporting an improved functional status of the kidneys after GSK484 treatment. Administration of GSK484 at a dose of 4 mg/kg daily during one week reverts signs of kidney dysfunction in tumor-bearing mice to the same extent as DNase I treatment, without any detectable signs of toxicity.
