Zanthobungeanine has anti-inflammatory activity, it shows moderate NO production inhibitory activity with an IC50 value of 37.26 mg /L.It shows obviously inhibitoryactivity to platelet aggregation caused by platelet-activating factor (PAF). Zanthobungeanine shows the inhibitory action on the development of A549 cell only in high concentration and has no antipersonnel effect on A549 cell.

Tetrahydroalstonine is an indole alkaloid extracted from the fruit of Rhazya stricta and is a selective α2-adrenoceptor antagonist. tetrahydroalstonine has shown antipsychotic activity in Rauwolfia tetraphylla.

Galantide 是一种特殊的甘丙肽受体 (galanin receptor) 拮抗剂，是一种由甘丙肽和 P 物质片段组成的肽段，在大鼠下丘脑可识别两类甘丙肽结合位点 (KD 分别小于 0.1 nM 和 ~6 nM)。Galantide 剂量依赖性 (IC50=1.0 nM) 拮抗甘丙肽介导的葡萄糖诱导的小鼠胰岛胰岛素分泌抑制。Galantide 似乎与单一的 SP 受体群结合 (KD~40 nM)。
