piper laetispicum/alkaloid

In the present work, we studied the effect of laetispicine, an amide alkaloid isolated from the stems of Piper laetispicum (Piperaceae), in forced swimming, open field, acetic acid writhing and formalin tests in KM mice to assess antidepressant and antinociceptive effects. A significant and

Piper laetispicum C.DC. (Piperaceae), is an endemic climbing, glabrous plant distributed in the southern part of China. A novel alkaloid amide, Laetispicine, from it has been proven to possess antidepressant activity. In this present study, antidepressant and antinociceptive effects of the ethyl

The first total synthesis of laetispicine (1a), an amide alkaloid isolated from the stems of Piper laetispicum C.DC (Piperaceae), and the synthesis of some of its derivatives were described. Based on the evaluation of antidepressant activities in the forced swimming test, compounds 1h and 1i were

Laetispicine, which is a novel amide alkaloid isolated from the stem of Piper laetispicum, has been proven to possess antidepressant and antinociceptive effects. This study examined the pharmacokinetic characteristics of laetispicine in plasma and brain distribution in rats by a simple sensitive
