and evaluated as BK channel openers in an assay system of CHO-K1 cells expressing hBKalpha channels. Systematic modifications of the peripheral functionality of ring C of DHAA showed that the introduction of a nitro or (thio)urea group in ring C greatly enhanced the BK channel-opening activity.
合成了一系列脱氢松香酸(DHAA,2)衍生物,并在表达hBKalpha通道的CHO-K1细胞分析系统中将其作为BK通道开放剂进行评估。DHAA的C环外围功能的系统修饰表明,在C环中引入硝基或(硫)脲基可大大增强BK通道的开放活性。
