Modification of the C-1 ketone of salvinorin A (2a) produces analogues with opioid antagonist properties. Of particular significance is the finding that 1-deoxo-1,10-dehydrosalvinorin A (11a) is a moderately potent antagonist at all three opioid receptor subtypes, and that herkinorin (2b), a mu agonist, is converted to a weak antagonist by removal of the C-1 ketone (3b and 11b). These observations
Salvinorin A (2a) 的 C-1 酮的修饰产生具有阿片拮抗剂特性的类似物。特别重要的是发现 1-deoxo-1,10-dehydrosalvinorin A (11a) 是所有三种阿片受体亚型的中效拮抗剂,并且 Herkinorin (2b),一种 mu 激动剂,通过以下方式转化为弱拮抗剂去除 C-1 酮(3b 和 11b)。这些观察结果表明 2b 的酮是负责 mu 激动剂活性的关键结构特征。
