Data Sheet 产品使用指南

CMLD-2 是一种 HuR-ARE 相互作用的抑制剂。CMLD-2 竞争性结合 HuR 蛋白，破坏其与富含腺嘌呤-尿苷元素 (ARE) 的 mRNA 靶标的相互作用 (K_i=350 nM)。CMLD-2 可诱导凋亡并在结肠癌，胰腺癌，甲状腺癌和肺癌细胞系中表现出抗肿瘤活性。Hu 抗原 R (HuR) 是一种 RNA 结合蛋白，可以调节靶标 mRNA 的稳定性和翻译。

生物活性

CMLD-2, an inhibitor of HuR-ARE interaction, competitively binds HuR protein disrupting its interaction with adenine-uridine rich elements (ARE)-containing mRNAs (K_i=350 nM). CMLD-2 induces apoptosis exhibits antitumor activity in different cancer cells as colon, pancreatic, thyroid and lung cancer cell lines. Hu antigen R (HuR) is an RNA binding protein, can regulate target mRNAs stability and translation.

体外研究

CMLD-2 (1-75 μM; 24-72 h) inhibits thyroid cancer cell viability.
CMLD-2 (20-30 μM; 24-48 h) activates caspases and induces apoptotic cell death in H1299 and A549 cells.
CMLD-2 (30 μM; 24-48 h) induces G1 cell cycle arrest and mitochondrial perturbation in H1299 and A549 cell.
CMLD-2 (30 μM; 24-48 h) reduces expression of HuR and HuR-regulated mRNAs and proteins in H1299 cells.
CMLD-2 (35 μM; 72 h) decreases directional migration capability in SW1736, 8505C, BCPAP and K1 cells. CMLD-2 induces a strong decrease of MAD2 mRNA levels in SW1736, 8505C, BCPAP and K1 cells.
