| 产品描述: | KN-93 Phosphate 是一种强效的特异性的Ca2+/calmodulin-dependent protein kinase II (CaMKII)抑制剂,其 Ki 为 0.37 μM,对 APK, PKC, MLCK 或 Ca2+-PDE 没有明显的抑制活性。KN-93 可减弱CaMKII诱导的自噬 |
| 靶点: |
CaMKII(Cell-free assay):0.37 μM(Ki) |
| 体外研究: |
KN-93抑制PC12h细胞中多巴胺的形成,通过调整TH的反应率,以减少Ca(2+)介导的TH分子磷酸化水平。KN-93抑制血清诱导的成纤维细胞生长,IC50 为8 μM,并在延长的G1期阻滞后诱导细胞凋亡。在PCa 细胞中,KN-93抑制雄激素受体活性和p53单独诱导的细胞死亡 |
| 体内研究: |
在患帕金森病的大鼠模型中,KN-93 (5 微克) 通过降低pGluR1S845的表达改善左旋多巴诱发的异动症。在MRL/lpr Foxp3-GFP小鼠体内,KN-93引起脾脏,外周淋巴结和外周血中显著的调节性T细胞感应,并减少皮肤和肾脏损害 |
| 细胞实验: |
Cell lines: NIH 3T3 成纤维细胞 Concentrations: ~24 μM Incubation Time: 70小时 Method: NIH3T3成纤维细胞在含DMEM和胎牛血清的聚苯乙烯皿中培养,在37℃,5%CO2加湿的房间用青霉素/链霉素进行增补。细胞的生长通过MTT色素还原法测定 |
| 动物实验: |
Animal Models: Sprague Dawley 雌性大鼠 Dosages: ~5 微克 Administration: 纹状体内给药 |
