LX7101

LX7101 is a pyrrolopyrimidine-based, topically-delivered inhibitor of LIM domain kinase 2 (LIMK2), a kinase associated with the regulation of intraocular pressure. LX7101 is also a ROCK inhibitor used for the treatment of glaucoma. LX7101 acts by enhancing fluid outflow through the trabecular meshwork of the eye. Preclinical studies indicate that LX7101 significantly reduced intraocular pressure in both mouse and monkey models. The latest stage of development for LX7101 was a randomized, double-blind, placebo-controlled Phase 1/2a trial for patients with open angle glaucoma or ocular hypertension.

How to use

In Vitro:

LX7101 is a dual LIM-kinase and ROCK inhibitor for the treatment of ocular hypertension and associated glaucoma. LX-7101 also displays potent inhibition of Akt1 with an IC50 of less than 1 nM. The overall selectivity of LX7101 for LIMK2 increases at the higher physiological ATP concentrations. Under physiological conditions, the activity of LX7101 is primarily due to inhibition of LIMK2.

In Vivo:

LX-7101 is advanced to Phase-I clinical trials as an intraocular pressure (IOP)-lowering agent for treatment of glaucoma. LX-7101 displays a significant IOP reduction at time points ranging from 1 h to 6 h post administration in rabbits. Topical doses of LX-7101 are evaluated for tolerability on the eyes of mice, rats, and rabbits. It is well tolerated at doses up to 0.5% in non-GLP single dose studies. In the mouse IOP assay, LX-7101 (5%) achieved additional reduction of IOP (5.0 mmHg total reduction) compared to the 0.1% formulation and demonstrated a long duration of action, with IOP not returning to baseline until more than 8 h postdose.
