LY2812223 is a highly effective and functionally selective mGlu2 receptor agonist. It has a mGlu2 binding affinity for mGlu2 and mGlu3 (Ki=144 nM and 156 nM, respectively).
LX7101 is a potent inhibitor of both LIMkinase (LIMK) 1 and 2, and Rho-associated kinase 1 (ROCK1) and ROCK2, with IC50 values of 32, 4.3, 69, and 32 nM, respectively. It is selective, demonstrated by its lack of cross-reactivity in a panel of binding assays involving 78 receptors, transporters, and an additional 430 kinases, at a concentration of 10 μM. The topical administration of LX7101 (3 μl of a 1 mg ml solution) to the eye has been shown to reduce intraocular pressure in a dexamethasone-induced mouse model of glaucoma.
Cucurbitacin I, cytotoxic triterpenoid sterols isolated from plants, elicits the formation of actin phospho-myosin II co-aggregates by stimulation of the RhoA ROCK pathway and inhibition of LIM-Kinase.
