Lei-Dab7 

Lei-Dab7 is a potent and selective SK2 (KCa2.2) channels blocker with a K_d of 3.8 nM. Lei-Dab7 shows low or no activity on KCa1, KCa3, Kv and Kir2.1 channels^[1][2].

Intracerebroventricular (9-5 ng) injections of Lei-Dab7 decreases locomotor activity, food intake and body weight in rats deprived of food. A dose of 3 ng Lei-Dab7 has no effect on these types of behavior^[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
