Disclosed herein are a compound of formula (I) and a preparation method and uses thereof. The compound shows a good inhibitory activity against ROCK, providing a new medicinal strategy to clinically treat the diseases associated with abnormal ROCK activity. 

Rock-inhibiting compound and uses thereof

A particulate profile control agent self-adaptive to a size of formation pore throat and a preparation method thereof include: raw materials and mass fraction for preparing a system including a main agent of 0.04&#x2dc;0.2%, a nucleating agent of 0.005&#x2dc;0.01%, a crosslinking agent of 0.002&#x2dc;0.04%, an additive of 0.005&#x2dc;0.01% and water. The preparation method includes: adding the main agent in proportion to the water and evenly mixing the mixture of the main agent and the water, and then adding the additive, the crosslinking agent and the nucleating agent in turn so as to form the profile control agent; pumping the profile control agent into the formation to be reacted at a reservoir temperature for a period of time to form colloidal particles on the spot for sealing off a high-permeability layer. The present disclosure is of easy operation and low cost, low initial viscosity and good injectivity.
