Novel oxime and oxime ether derivatives of 12,14-dichlorodehydroabietic acid: design, synthesis, and BK channel-opening activity.
Oxime ether derivatives of the benzylic ketone of 12,14-dichlorodehydroabietic acid (diCl-DHAA, 4b) were synthesised, and their BK channel-opening activity was evaluated in an assay system of CHO-K1 cells expressing hBKalpha channels. Oxime ether structure on the B ring of diCl-DHAA significantly increased the BK channel-opening activity.
