Effects of pimaric acid (PiMA) and eight closely related com-pounds on large-conductance K (BK) channels were exam-ined using human embryonic kidney (HEK) 293 cells, in which either the subunit of BK channel (HEKBK) or both and 1 (HEKBK1) subunits were heterologously expressed. Effects of these compounds (10 M) on the membrane potential of HEKBK1 were monitored by use of DiBAC4(3), a voltage-sensitive dye. PiMA, isopimaric acid, sandaracoisopimaric acid, dihydropimaric acid, dihydroisopimaric acid, and dihydroisopi-marinol induced substantial membrane hyperpolarization. The direct measurement of BK1 opening under whole-cell volt-age clamp showed that these six compounds activated BK1 in a very similar concentration range (1–10 M); in con...
