pace 4

PACE4 Inhibitory peptide C23 (Compound C23) 是一种强效的拟肽抑制剂，作为PACE4抑制剂，对PCa细胞系表现出抗增殖作用 (Ki= 5 nM)，对DU145和LNCaP细胞的IC50值分别为25 μM和40 μM。同时，PACE4 Inhibitory peptide C23 也能够在LNCaP异种移植小鼠模型中抑制肿瘤生长。

Hexa-D-arginine 是稳定的furin 抑制剂，能够作用于 furin (Ki:106 nM)、PACE4 (Ki:580 nM)、PC1 (Ki:13.2 nM)。它在体外和体内均可阻断假单胞菌外毒素 A 和炭疽毒素的毒性。

(±)10-HDHA is an autoxidation product of docosahexaenoic acid (DHA) in vitro.[1][2] It is also produced from incubations of DHA in rat liver, brain, and intestinal microsomes.[3][4][5] (±)10-HDHA is a potential marker of oxidative stress in brain and retina where DHA is an abundant polyunsaturated fatty acid.
