RA-2 is a potent and selective KCa2/3 pan inhibitor with negative-gating modulator properties (IC50 values of 17 and 2 nM for KCa3.1 and KCa2.3, respectively). RA-2 inhibited EDH-type dilations in porcine coronary arteries (PCAs) and was found not to increase blood pressure in telemetry recordings despite reducing heart rate (HR).
