CAS#: 1380341-99-0

Description: GAL-021 is a large conductance calcium-activated potassium channel (BKCa-channel) blocker potentially for the treatment of respiratory depression. GAL-021 inhibited KCa1.1 in GH3 cells, and the evoked ventilatory stimulation was attenuated in Slo1 mice lacking the pore-forming α-subunit of the KCa1.1 channel. At a higher concentration of GAL-160 (100 μM), inhibition of the delayed rectifier K(+) current and leak K(+) current were observed.
