NS13001 is primarily used in research settings as a potent and selective inhibitor of the SK3 potassium channel, which plays a significant role in cellular processes such as membrane potential regulation and calcium signaling. Its application is particularly valuable in neuroscience studies, where it helps to investigate the role of SK3 channels in neuronal excitability and synaptic transmission. Additionally, NS13001 has been explored in the context of cancer research, as SK3 channels are implicated in the regulation of cancer cell migration and proliferation. By inhibiting these channels, NS13001 provides insights into potential therapeutic strategies for targeting cancer metastasis. Its use extends to studying conditions like epilepsy and other neurological disorders, where SK3 channel dysfunction may be a contributing factor. Overall, NS13001 serves as a critical tool for understanding the physiological and pathological roles of SK3 channels in various biological systems.
