cp21

CP21 is an iron chelator that binds to iron in a 3:1 (ligand:iron) ratio. It is active against P. falciparum when used at concentrations of 10 and 100 µM. CP21 inhibits production of prostaglandin I2 induced by epinephrine, arachidonic acid, or A23187 in isolated rat aortic rings with IC50 values of 1.3, 1.3, and 1.4 mM, respectively. It inhibits glutamate-induced oxytosis, as well as decreases iodoacetic acid-induced cytotoxicity in an in vitro model of ischemia, in HT22 mouse hippocampal cells (EC50s = 13 and 9.5 µM, respectively). CP21 (200 mg kg) increases the excretion of iron, but not copper, zinc, calcium, or magnesium, in rabbits.

CP21R7 (CP21) 是一种 GSK-3β抑制剂，其 IC50=1.8 nM。它也是一种 PKCα抑制剂，其 IC50=1900 nM。
