ROCK2 IN COMPLEX WITH 1426382-07-1
Structural highlights
FunctionROCK2_HUMAN Protein kinase which is a key regulator of actin cytoskeleton and cell polarity. Involved in regulation of smooth muscle contraction, actin cytoskeleton organization, stress fiber and focal adhesion formation, neurite retraction, cell adhesion and motility via phosphorylation of ADD1, BRCA2, CNN1, EZR, DPYSL2, EP300, MSN, MYL9/MLC2, NPM1, RDX, PPP1R12A and VIM. Phosphorylates SORL1 and IRF4. Acts as a negative regulator of VEGF-induced angiogenic endothelial cell activation. Positively regulates the activation of p42/MAPK1-p44/MAPK3 and of p90RSK/RPS6KA1 during myogenic differentiation. Plays an important role in the timely initiation of centrosome duplication. Inhibits keratinocyte terminal differentiation. May regulate closure of the eyelids and ventral body wall through organization of actomyosin bundles. Plays a critical role in the regulation of spine and synaptic properties in the hippocampus.[1] [2] [3] [4] [5] [6] [7] [8] Publication Abstract from PubMedROCK1 and ROCK2 play important roles in numerous cellular functions, including smooth muscle cell contraction, cell proliferation, adhesion and migration. Consequently, ROCK inhibitors are of interest for treating multiple indications including cardiovascular diseases, inflammatory and autoimmune diseases, lung diseases and eye diseases. However, systemic inhibition of ROCK is expected to result in significant side effects. Strategies allowing reduced systemic exposure are therefore of interest. In a continuing effort towards identification of ROCK inhibitors, we here report the design, synthesis and evaluation of novel soft ROCK inhibitors displaying an ester function allowing their rapid inactivation in the systemic circulation. Those compounds display sub-nanomolar activity against ROCK and strong differences of functional activity between parent compounds and expected metabolites. The binding mode of a representative compound was determined experimentally in a single-crystal X-ray diffraction study. Enzymes responsible for inactivation of these compounds once they enter systemic circulation are also discussed.
