HuR

CMLD-2 is an inhibitor of HuR-ARE interaction (Ki: 350 nM) that competitively binds HuR protein and disrupts its interaction with adenine element-rich (ARE) mRNA targets.CMLD-2 induces apoptosis and exhibits antitumor effects through MAD2 downregulation. CMLD-2 (1-75 μM ; 24-72 h) had an inhibitory effect on the viability of thyroid cancer cells.CMLD-2 (20-30 μM ; 24-48 h) activated caspases and induced apoptosis in H1299 and A549 cells.CMLD-2 (30 μM ; 24-48 h) induced G1 cell cycle arrest in H1299 and A549 cells and mitochondrial perturbation. CMLD-2 (30 μM ; 24-48 h) reduced the expression of HuR and HuR-regulated mRNAs and proteins in H1299 cells.CMLD-2 (35 μM ; 72 h) decreased the directional migration ability of SW1736, 8505C, BCPAP and K1 cells.CMLD-2 induced the migration of SW1736, 8505C, BCPAP and K1 cells with a strong decrease in MAD2 mRNA levels.

NSC243928 mesylate binds to human lymphocyte antigen 6 (LY6), a cell growth inhibitor with anticancer activity, and induces cell death in triple-negative breast cancer cells in a LY6K-dependent manner.

SRI-42127 is a novel small molecule inhibitor of the RNA regulatory factor HuR, which inhibits tumor growth, attenuates glial activation in a lipopolysaccharide-induced neuroinflammation model, and reduces neuropathic pain after nerve injury by inhibiting the neuroinflammatory response.
