UCL 1684 (dibromide) is a first nanomolar, non-peptidic small conductance calcium-activated potassium (SK) channel blocker. UCL 1684 (dibromide) is effective in preventing the development of atrial fibrillation due to potent atrial-selective inhibition of INa. UCL 1684 (dibromide) causes atrial-selective prolongation of ERP secondary to induction of postrepolarization refractoriness[1][2][3].

In Vitro	UCL 1684 (dibromide) (0.5 μM; HEK cells) produces direct atrial-selective inhibition of sodium channel current (INa) and shifts SS inactivation of the cardiac sodium channels. UCL 1684 (dibromide) (0.5 μM) induces PRR, decreases V max, increases DTE, and extends the shortest S1-S1 interval[1].
In Vivo	UCL 1684 (dibromide) (3 mg/kg; i.v.) increases wenckebach cycle length to 115.0±5.1 % of baseline value[3].
