Abstract
Description
[Technical field]
[0001] The present invention relates to the field of biomedicine, specifically to Rho-associated protein kinase inhibitors and their preparation and application. [Background technology]
[0002] Rho-associated kinases (ROCKs) are serine / threonine kinases of the AGC kinase family, which includes two subtypes, ROCK1 and ROCK2. ROCK2 (ROCKα) was first identified as a RhoA-binding protein, and ROCK1 (ROCKβ or p160ROCK) was subsequently discovered as a RhoA-binding protein with high homology to ROCK2. RhoA is a GTPase that is activated after binding to GTP and promotes the activation of downstream effector factors. ROCKs have been extensively studied over the past 20 years and, as the main effector factors of RhoA protein, achieve their biological functions by phosphorylating downstream effector proteins (MYPT1, MLC, Moesin, etc.). Currently, more than 30 substrates of ROCKs have been identified, which are involved in the regulation of multiple processes, such as cytoskeleton dynamics, cell morphology, and cell contraction. The most studied and reported substrate is myosin phosphatase target subunit 1 (MYPT1), which is the myosin-binding subunit of myosin light chain phosphatase (MLCP). ROCKs mediate phosphorylation of MYPT1 at Thr697 and Thr855 sites to inhibit the catalytic activity of MLCP, thereby controlling the phosphorylation of myosin regulatory light chain (MLC) and affecting the generation of cellular contractile force. Studies have shown that the occurrence of fibrosis, cardiovascular disease, metabolic disease, neurological disease, and cancer are associated with ROCKs-mediated pathways, and therefore ROCKs are considered to be an important target point for the treatment of these diseases.
[0003] The amino acid sequence similarity between ROCK1 and ROCK2 reaches 64%, the kinase domain similarity reaches 92%, and the two subtypes share some common effector proteins. Currently, various small molecule ROCK inhibitors have been reported, where most inhibitors have equivalent inhibitory activity against both ROCKs subtypes. Currently, only two ROCK inhibitors have been approved for clinical use as topical drugs: Fasudil, which was the first approved drug for treating cerebral vasospasm in Japan and China, and Ripasudil, which was approved for treating glaucoma in Japan. Simultaneous inhibition of the two ROCKs subtypes can cause potential side effects such as hypotension, so there are currently no small molecule ROCK inhibitors suitable for systemic administration. The development of small molecule inhibitors targeting specific subtypes will be an important direction in drug development targeting ROCK.
