Isopimaric acid | Potassium channel activator

Isopimaric acid (5835-26-7) is a terpenoid acid that activates BK (voltage-gated potassium) channels when used at 10 µM in HEK293 cells.1 Improves spatial and non-spatial memory in Alzheimer’s mouse model2,3, and significantly improves motor function in a rat spinal cord injury model4. Reduces hyperactivity of spontaneously active auditory networks, EC50=7.8 μM.5
