Abstract

Rho-associated coiled coil kinase (ROCK) plays a pivotal role in regulating actin cytoskeleton remodeling and cellular motility, establishing it as a promising therapeutic target for metastatic breast cancer. Guided by the lead compound belumosudil, a novel series of ROCK2 inhibitors based on a 6-amino-2-piperazine pyridine scaffold was designed and synthesized. The Kinase-Glo assay identified compound 14r as the most potent analog, showing an IC50 value of 82.6 nM, which represented a 1.2-fold improvement over belumosudil. Furthermore, the morphology of MDA-MB-231 cells treated with 14r was significantly changed in immunofluorescent staining analysis. Simultaneously, cell scratch experiments showed that 14r inhibited the migration of MDA-MB-231 cells in a dose-dependent manner. Additionally, molecular docking studies elucidated the binding mode of 14r within the ROCK2 ATP pocket, corroborating its nanomolar-level inhibitory activity. In conclusion, 14r showed great potential for further optimization to suppress breast cancer metastasis.

具有抗乳腺癌转移效率的6-氨基-2-哌嗪基吡啶类ROCK2抑制剂的合理设计
rho相关的卷曲卷曲激酶(ROCK)在调节肌动蛋白细胞骨架重塑和细胞运动中起关键作用,使其成为转移性乳腺癌的有希望的治疗靶点。在先导化合物白莫硫地尔的指导下,设计并合成了一系列基于6-氨基-2-哌嗪吡啶支架的新型ROCK2抑制剂。激酶- glo实验鉴定化合物14r是最有效的类似物,其IC50值为82.6 nM,比白莫硫地尔提高1.2倍。此外,免疫荧光分析显示,14r处理后的MDA-MB-231细胞形态发生了显著变化。同时,细胞划痕实验显示,14r抑制MDA-MB-231细胞的迁移,并呈剂量依赖性。此外,分子对接研究阐明了14r在ROCK2 ATP口袋内的结合模式,证实了其纳米级的抑制活性。综上所述,14r具有进一步优化抑制乳腺癌转移的潜力。
