Sideritoflavone has anti-inflammatory effect, it is a selective inhibitor of lipoxygenase activity in vitro.

Biphalin TFA 是能穿透血脑屏障的阿片类肽，具有双活性脑啡肽效应团。该化合物对阿片受体有高亲和力，并在急性、神经性及慢性疼痛动物模型中展现了显著的镇痛活性。此外，Biphalin TFA 还具有抗病毒、抗增殖、抗炎以及神经保护的特性。

β-Lipotropin (61-69) 是一种有效的阿片 (opioid) 激动剂。

Potent, selective partial agonist peptide for the NOP receptor (Ki = 0.71 nM). Selective over μ, δ and κ opioid receptors (IC50 > 4000 nM). Increases food intake in vivo.

Bilaid C is a tetrapeptide μ-opioid receptor agonist (Ki= 210 nM in HEK293 cell membranes expressing the human receptor) that has been found inPenicillium.1It inhibits forskolin-induced cAMP accumulation by 77% in HEK293 cells expressing the human μ-opioid receptor when used at a concentration of 10 μM. Bilaid C induces inward rectifying potassium channel (Kir) currents in rat locus coeruleus slices that endogenously express high levels of the μ-opioid receptor (EC50= 4.2 μM). 1.Dekan, Z., Sianati, S., Yousuf, A., et al.A tetrapeptide class of biased analgesics from an Australian fungus targets the μ-opioid receptorProc.
