Background:

CMLD-2, an inhibitor of HuR-ARE interaction, competitively binds HuR protein disrupting its interaction with adenine-uridine rich elements (ARE)-containing mRNAs (Ki=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[1][2].

CMLD-2 (1-75 μM; 24-72 h) inhibits thyroid cancer cell viability[2].CMLD-2 (20-30 μM; 24-48 h) activates caspases and induces apoptotic cell death in H1299 and A549 cells[3].CMLD-2 (30 μM; 24-48 h) induces G1 cell cycle arrest and mitochondrial perturbation in H1299 and A549 cell[3].CMLD-2 (30 μM; 24-48 h) reduces expression of HuR and HuR-regulated mRNAs and proteins in H1299 cells[3].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[2]. Cell Viability Assay[2] Cell Line: SW1736, 8505C, BCPAP and K1 cells
