Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	ROCK1 ^[1] (Cell-free assay) 140 nM(Ki) ROCK2 ^[1] (Cell-free assay) 300 nM(Ki)
In vitro	Y-27632 primes human induced pluripotent stem cells (hIPSCs) to selectively differentiate towards mesendodermal lineage via epithelial-mesenchymal transition-like modulation.^[2]
In vivo	Y27632, a specific inhibitor of ROCK, supresses ROCK as well as altered pathways and leads to a significant enhancement in corneal nerve regeneration.^[3]
