Netarsudil dimesylate
Based on 1 publication(s) in Google Scholar
Netarsudil (AR-13324) dimesylate is a competitive inhibitor of Rho-associated protein kinases (ROCK I and ROCK II) and a reversible inhibitor of the norepinephrine transporter (NET). Netarsudil dimesylate reduces intraocular pressure by inhibiting ROCK, causing relaxation of trabecular meshwork cells and dilation of episcleral veins, thereby increasing the ease of aqueous humor outflow, while inhibiting NET to reduce aqueous humor production. Netarsudil dimesylate is mainly used in the study of ocular hypertension and primary open-angle glaucoma.

Biological Activity
Netarsudil dimesylate exerts its effects by metabolizing to the active compound Netarsudil-M1. Netarsudil-M1 (0.3 μM; 3 h) significantly increases aqueous humor outflow ease in human ocular tissue perfusion experiments and increases effective filtration length (PEFL) by dilating the trabecular meshwork (TM) and episcleral veins (ESV)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Human trabecular meshwork cells
-
Concentration:0.3 μM Netarsudil-M1
-
Incubation Time:24 h
-
Result:Actin Stress Fibers: Reduced formation of actin stress fibers and focal adhesions, accompanied by cell rounding and detachment, indicative of relaxed cell contractility.
Immunofluorescence Staining: Decreased phosphorylation of myosin light chain (MLC), a marker of ROCK-mediated contraction, confirming inhibition of the Rho-kinase pathway.
Netarsudil dimesylate (0.04% eye drops; topical instillation; once daily; 3 days) significantly reduces intraocular pressure and episcleral venous pressure in male Dutch DB rabbits without affecting arterial pressure, heart rate, and carotid blood flow[3].

Animal Model:Male Dutch Belted rabbits (2.15±0.09 kg, male) episcleral venous pressure (EVP) and IOP measurement model[3]
-
Dosage:0.04% Netarsudil ophthalmic solution (aqueous solution with 0.015% benzalkonium chloride).
-
Administration:Topical instillation of 1 drop once daily for 3 days.
-
Result:Baseline values: IOP 34±4 mmHg, EVP 17±2 mmHg, arterial pressure (AP) 105±3 mmHg, carotid blood flow (BFcar) 35±1 mL/min, heart rate (HR) 337±9 bpm.
Three hours after the final dose, IOP decreased by 39% to 19±2 mmHg, EVP decreased by 35% to 11±1 mmHg.
AP, BFcar, and HR showed no significant changes throughout the experiment, indicating no systemic hemodynamic effects.
-
Animal Model:Female cynomolgus monkeys (3-5 kg, female, adult) aqueous humor dynamics model[2]
-
Dosage:0.04% Netarsudil ophthalmic solution (aqueous formulation).
-
Administration:Opical instillation of 50 μL (25 μL×2) as a single dose.
-
Result:Six hours post-treatment, outflow facility (C) increased by 53% compared to baseline, from 0.58±0.07 to 0.90±0.11 μL/min/mmHg.
Aqueous humor flow rate (F) decreased by 23% compared to baseline, from 1.60±0.11 to 1.25±0.19 μL/min.
IOP was reduced by 25% compared to baseline, with no significant changes observed in contralateral vehicle-treated eyes.
