Route of Administration: Topical
In Vitro Use Guide
Curator's Comment: At 10 uM, Netarsudil (AR-13324) inhibits NET by 96% and SERT by 94%. In a kinase screening panel 0.5 uM AR-13324 inhibited 11 kinases by >90%. https://www.ncbi.nlm.nih.gov/pubmed/27072905
Netarsudil inhibited kinases ROCK1 and ROCK2 with a Ki of 1 nM each, disrupted actin stress fibers and focal adhesions in TM cells with IC50s of 79 and 16 nM, respectively, and blocked the profibrotic effects of TGF-β2 in HTM cells.
