Abstract
The analgesic potential of six 14-membered-ring cyclopeptide alkaloids, namely, franganine (1), discarine B (2), scutianines B (3), C (4), and D (5), and adouetine X (6), have been investigated. Among the compounds tested, only franganine (1) and adouetine X (6) produced antinociceptive effects in a mouse model of acute pain, without inducing undesirable side effects. Furthermore, compound 6 also exhibited a pronounced analgesic effect in a chronic neuropathic pain model in mice. It has been found that adouetine X (6) can decrease the activities of Ca(2+)-ATPase and Na(+)/K(+)-ATPase in vitro. Thus, the present findings have demonstrated that adouetine X (6) is a promising analgesic agent.
