Abelson tyrosine kinase (c-Abl) is involved in various biological processes in neurodegenerative diseases and is an attractive target for anti-PD (Parkinson's disease) drug discovery. Based on our previous work, we designed several novel c-Abl inhibitors through a conformational constrained strategy and evaluated their pharmacological activities. Among them, compound A6 exhibited superior inhibitory
Abelson 酪氨酸激酶 (c-Abl) 参与神经退行性疾病的各种生物过程,是抗 PD(帕金森病)药物发现的一个有吸引力的靶标。基于我们之前的工作,我们通过构象约束策略设计了几种新型c-Abl抑制剂并评估了它们的药理活性。其中,在均相时间分辨荧光(HTRF)测定中,化合物A6对c-Abl表现出优于尼罗替尼的抑制活性。此外,与尼洛替尼相比, A6对 MPP +诱导的 SH-SY5Y 细胞死亡表现出更高的神经保护作用和更低的细胞毒性。分子模型显示,1H-吡咯并[2,3- B ]吡啶环可能有助于A6与c-Abl结合的高亲和力。总的来说,这些结果表明A6作为神经退行性疾病的 c-Abl 抑制剂值得进一步研究。
