contractility, shape, motility, and invasion of cells. We explored the relationships between structure and anti-ROCK2 activity in a group of purine derivatives substituted at the C6 atom by piperidin-1-yl or azepan-1-yl groups. Structure-activity relationship (SAR) analyses suggested that anti-ROCK activity is retained, and may be further increased, by substitution of the parent compounds at the C2 atom or by expansion
Rho相关的丝氨酸/苏氨酸激酶(ROCKs)是肌动蛋白细胞骨架的主要调节剂,可调节细胞的收缩性,形状,运动性和侵袭性。我们探索了在一组碳素原子上被哌啶-1-基或氮杂-1-基取代的嘌呤衍生物的结构与抗ROCK2活性之间的关系。结构活性关系(SAR)分析表明,通过在C2原子处取代母体化合物或通过扩展C6侧链,可以保留抗ROCK活性,并且可以进一步提高抗ROCK活性。这些ROCK抑制剂可以在细胞内达到有效浓度,这可以通过ROCK靶MLC磷酸化的减少以及抑制ROCK依赖的黑色素瘤细胞在胶原蛋白基质中的侵入来证明。
