Z-Arg-Lys-AOMK
Z-Arg-Lys-AOMK is a cathepsin B inhibitor that can cross the blood-brain barrier. Z-Arg-Lys-AOMK reduces cytosolic cathepsin B activity in homogenates of mouse cerebral cortex and hippocampal tissues, and alleviates motor dysfunction associated with CCI-TBI. Z-Arg-Lys-AOMK can be used in the research of traumatic brain injury.

Biological Activity
Z-Arg-Lys-AOMK (1.7-5536 nM; 30 min) potently and selectively inhibits recombinant mouse cathepsin B at neutral pH 7.2 (IC50 = 25 nM) with 100-fold lower potency at acidic pH 4.6, and does not inhibit other mouse cysteine cathepsins (C, H, L, X) at relevant concentrations[1].

Animal Model:C57BL/6J mice (female, adult, 4-5 months of age, traumatic brain injury CCI model)[1]
-
Dosage:20 mg/kg
-
Administration:i.p.; daily; 7 consecutive days (starting 1 day pre-CCI-TBI through day 6 post-CCI-TBI)
-
Result:Reduced CCI-TBI-induced cytosolic cathepsin B activity in the ipsilateral brain cortex from ~400 pmol AMC/μg protein to ~275 pmol AMC/μg protein .
Reduced CCI-TBI-induced cytosolic cathepsin B activity in the contralateral cortex from ~200 pmol AMC/μg protein to ~220 pmol AMC/μg protein.
Reduced cathepsin B activity in ipsilateral brain cortex homogenates from ~1750 pmol AMC/μg protein to ~1000 pmol AMC/μg protein.
Reduced cathepsin B activity in ipsilateral hippocampus homogenates from ~1700 pmol AMC/μg protein to ~800 pmol AMC/μg protein.
Improved rotarod motor function on day 1 post-CCI-TBI, increasing latency from ~35% of baseline to ~55% of baseline.
