NS 1619 (153587-10-0) is a selective activator of large conductance Ca(2+)-dependent potassium channels (BKCa or KCa1.1).1,2  It was able to increase blood-brain tumor barrier permeability in rat brain tumor models.3,4 NS 1619 inhibited proliferation and induced apoptosis in A2780 ovarian cancer cells.Displays cardioprotective effects in an ischemia-reperfusion model6 and neuroprotective effects in a traumatic brain injury model7.
