Clemizole-d4
Based on 1 Customer Validation
Clemizole-d4 is the deuterated-labeled Clemizole (HY-30234). Clemizole is an orally active, blood-brain barrier permeable TRPC5 inhibitor, with an IC50 value of 1.05-1.34 μM against mouse TRPC5. Clemizole blocks TRPC1:TRPC5, TRPC3, TRPC4, TRPC6, TRPC7, hERG, hKCNQ1/hKCNE1 and hKv1.5 channels, and activates TRPA1; it modulates 5HT-2B and HTR2A receptors; it inhibits HCV RNA replication, CrtN enzymatic activity, oxidative stress, neuroinflammation, cell apoptosis and bacterial virulence; it maintains blood-brain barrier (BBB) integrity; it enhances DNA repair capacity; it improves cell viability; and it alters cardiac electrophysiological properties. Clemizole can be used in the research of Dravet syndrome, hepatitis C virus infection, Staphylococcus aureus skin infection, Cisplatin (HY-17394)-induced nephrotoxicity, STXBP1-related diseases, traumatic brain injury and xeroderma pigmentosum type C.
