Steppogenin exhibits significant tyrosinase inhibition activity, ;it also shows strong mushroom tyrosinase inhibitory activity with IC(50) values lower than 50 microM, more potent than kojic acid (IC(50) = 71.6 microM), a well-known tyrosinase inhibitor.

Fumarate hydratase-IN-1 (compound 2) 是一种细胞可渗透性的富马酸水合酶 (fumarate hydratase) 抑制剂。Fumarate hydratase-IN-1 对几种细胞系具有抗增殖活性，平均 IC50 为 2.2 μM。

α-Conotoxin M I 是 mAChR 和 α1β1γδ nAChR 的选择性和有效的抑制剂，但对尼古丁刺激的多巴胺释放无影响。α-Conotoxin 毒素是一种小的、富含二硫的多肽，竞争性地抑制肌肉和神经元的尼古丁 AChR。
