| 产品描述: | LB-100 is a water soluble protein phosphatase 2A (PP2A) inhibitor. Phase 1. |
| 靶点: |
Phosphatase |
| 体外研究: |
在胰腺癌异种移植小鼠模型中, LB-100(2 mg/kg,i.p.)可增加化疗药物阿霉素的疗效.LB-100使肿瘤表面血流速度和肿瘤微血管密度增加 |
| 体内研究: |
与对照组相比,LB-100使细胞内阿霉素浓度升高约2.5倍,并增加肿瘤细胞对阿霉素的敏感性。LB-100使血管内皮生长因子分泌增加,从而促进HIF-1α-VEGF介导的血管生成。LB-100对BxPc-3(IC50:2.3 μM)和Panc-1(IC50:1.7 μM)细胞的生长有明显抑制效果。经LB-100处理后,BxPc-3、SW1990和Panc-1细胞肿的PP2A活性下降30-50% |
| 细胞实验: |
Cytotoxicity is conducted by using a Cell Counting Kit-8. Cells are seeded in 96-well plates with a density of 3000 cells per well and are assessed after treatments following the CCK-8 protocol. Relative cytotoxicity is expressed as a percentage of speci?c controls. (Only for Reference) |
