β-Lipotropin (60-65) (β-LPH (60-65)) 是一种阿片类肽，是一种有效的阿片类激动剂。

δ1 opioid receptor antagonist

Enkephalin-met, ala(2)- is a synthetic analog of methionine enkephalin.

6β-Naltrexol 是一种强效的外周选择性阿片antagonist。与中枢作用的阿片拮抗剂不同，6β-Naltrexol 主要局限于外周组织，因此能够抵消阿片类药物所致的外周副作用（如 阿片诱导的便秘），同时最大限度减少对中枢神经系统的干扰。因此，6β-Naltrexol 在外周阿片效应的研究中具有重要意义。

Ro 64-6198 is a nonpeptide, high-affinity, and brain penetration N/OFQ receptor (NOP) agonist (EC50: 25.6 nM). Ro 64-6198 is at least 100 times more selective for the NOP receptor over the classic opioid receptors.

(±)-J-113397 是一种有效的、高选择性的非肽基ORL1 受体拮抗剂，对人克隆 ORL1 的Ki 为 1.8 nM。在体外，J-113397 抑制 nociceptin/orphanin FQ 刺激的GTPγS 与表达 ORL1 的 CHO 细胞结合，IC50值为 5.3 nM。J-113397 可用于研究 nociceptin/orphanin FQ 的生理作用。
