ARL-17477 dihydrochloride may be used in cell signaling studies. ARL-17477 is an NOS1 (nNOS) specific inhibitor. The IC50 against rat nNOS is 35 nM and it has 100-fold selectivity over endothelial and inducible isoforms. ARL-17477 penetrates the brain, and reduces infarct size and reduces cerebral blood flow in several different rodent models of ischemic brain injury.
