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