Prolylleucine (((Benzyloxy)carbonyl)-L-prolyl-D-leucine) 是一种二肽，含有支链氨基酸，可以影响动物的昼夜节律和行为。

L-Cysteic acid monohydrate (3-Sulfo-L-alanine Monohydrate) 是内源性代谢产物的一种。

Neurotensin TFA (39379-15-2 free base) 是一种内源性 13 个氨基酸的神经肽，具有显着的阿片类非依赖性镇痛作用。它在大脑中充当神经递质，在肠道中充当激素，也充当神经调节剂。由于它与多种神经递质系统如多巴胺能、血清素能、谷氨酸能、GABA 能和胆碱能系统。它具有作为人体代谢物、有丝分裂原、神经递质和创伤的作用。

NPT200-11 是一种口服生物利用度和脑穿透性 ASYN 错误折叠和聚集抑制剂。 NPT200-11 可用于突触核蛋白病的潜在病理学研究，包括帕金森病 (PD)、路易体痴呆 (DLB) 和多系统萎缩 (MSA)。

JTP-4819 is a potent and selective prolyl endopeptidase (PEP) inhibitor with potential for treating Alzheimer's disease. At nanomolar concentration, JTP-4819 inhibited the degradation of substance P, arginine-vasopressin, and thyrotropin-releasing hormone by PEP in supernatants of the rat cerebral cortex and hippocampus. Repeated administration of JTP-4819 reversed the aging-induced decrease in brain substance P-like and thyrotropin-releasing hormone-like immunoreactivity, suggesting that this drug may be able to improve the imbalance of peptidergic neuronal systems that develops with senescense by inhibiting PEP activity. JTP-4819 increased acetylcholine release from the frontal cortex and hippocampus, regions closely associated with memory, in both young and aged rats.

CART(62-76)(human,rat) TFA 是一种类似神经递质的神经肽，由CART肽的62至76残基组成。该化合物能够调控纹状体去甲肾上腺素能、皮质纹状体及下丘脑在5-羟色胺能(5-HT)系统中的活性。

Dynorphin B 29 (Leumorphin) (pig) 是一种可与大脑及孤立组织系统中的多种受体交互作用的肽，并可被用于研究免疫反应。

Neuropeptide Y (22-36), a 15-amino acid fragment of Neuropeptide Y, is involved in various physiological and homeostatic processes in both the central and peripheral nervous systems.

Cereulide 是一种由蜡样芽孢杆菌产生的毒素肽。它可诱导细胞凋亡 (Apoptosis)，并作用于线粒体，导致不同器官[如肝脏、胰腺、脑、肠道等]和身体系统[如免疫系统和神经系统]的功能障碍。
