Description: KCa1.1 (BK) channel activator
Chemical Name: 5-[(4-Bromophenyl)methyl]-2-thiazolamine
Purity: ≥99% (HPLC)
Biological Activity for NS 19504
NS 19504 is a selective activator of large-conductance Ca2+-activated potassium channels (BKCa, KCa1.1) (EC50 = 11 μM). Activates BK channels in native smooth muscle cells from guinea pig bladder and reduces spontaneous phasic contractions in bladder strips ex vivo. Displays no effect on contractions induced by a high K+ concentration or at 65 other receptors tested, including L- and N- type Ca2+ channels, Nav, KATP and hERG channels.

Epilepsy Poster
Epilepsy is a brain disease that affects 60 million people globally. More than 20 anti-seizure drugs are currently available, but these do not address the underlying causes of the condition. This poster summarizes current knowledge about the development of the condition and highlights some approaches that have disease-modifying effects in proof-of-concept studies.
