| Hazard Information | Back Directory | [Description]
Netarsudil is a member of the aminoisoquinoline amide class of Rho-associated kinase (ROCK) inhibitors, binding reversibly to the ATP-binding sites of both ROCK1 and ROCK2 isoforms with low nanomolar affinity. As a 2,4-dimethylbenzoate ester prodrug of AR-13503, netarsudil offers enhanced permeability through the eye compared to the active drug. Upon ocular administration, it is absorbed through the cornea and metabolized by corneal esterases to release the more potent metabolite AR-13503, which has five times greater ROCK inhibitory activity than netarsudil itself.
 | [Uses]
Netarsudil is the first trabecular outflow drug approved in 2017 for lowering elevated intraocular pressure (IOP) in patients with open-angle glaucoma (OAG) or ocular hypertension. | [Brand name]

Treatment: glaucoma;
Other name: AR-13324;
Protein binding = >97% | [Biological Activity]
ki: 0.2-10.3 nmnetarsudil (ar-13324) is a rock inhibitor.the rho kinases are serine/threonine protein kinases existing as 2 isoforms, rock1 and rock2, which are widely expressed in various tissues, such as the trabecular meshwork. rock can promote the assembly of actin stress fibers and focal adhesions and can also regulate cell contraction and motility. | [in vitro]
previous study showed that at the cellular level, netarsudil had been shown to be able to induce loss of actin stress fibers, cell shape changes, loss of focal adhesions, as well as changes in extracellular matrix composition of tm cells [1]. | [in vivo]
animal efficacy study found that the topical treatment of netarsudil was able to affect both proximal (trabecular meshwork and schlemm's canal) and distal portions (intrascleral vessels) of the mouse conventional outflow tract [2]. | [target]
