Small Cardioactive Peptide B SCPB acetate (Small Cardioactive Peptide B SCPB acetate (84746-43-0 free base)) 是一种神经活性肽，可刺激心脏和鳃组织颗粒部分的腺苷酸环化酶活性，EC50 分别为 0.1 和 1.0 μM。

Amyloid-β (25-35) (Aβ (25-35)) is an 11-residue fragment of the Aβ protein that retains the physical and biological characteristics of the full length peptide. It forms fibrils that react to thioflavin T and Congo red and are organized in a cross-β arrangement of β-strands similar to Aβ (1-40) and Aβ (1-42) fibrils. Aggregated Aβ (25-35) decreases the viability of rat adrenal PC12 cells. It also decreases the viability of primary rat cortical neurons at concentrations ranging from 1 nM to 30 μM. In vivo, intracerebral injection of Aβ (25-35) (20 nmol) in rats induces lesions of neuronal and tissue loss. Aggregated Aβ (25-35) administered intracerebroventricularly to rats induces learning and memory impairments in the Y-maze, novel object recognition, and contextual fear conditioning tests.

β-Amyloid peptide(16-20)，即 Amyloid-β(Abeta) 的氨基酸序列(KLVFF)部分，有效抑制 Abeta 原纤维形成，通过在 N 和 C 末端添加 RG-/-GR-NH2 残基增强其溶解性。

SP-B peptide 是具有抗真菌活性的抗菌肽，有效针对新型隐球菌、白色念珠菌及烟曲霉菌株。

Thioether-cyclized helix B peptide (CHBP) 通过抑制 mTORC1 及激活 mTORC2 诱导的自噬增强代谢稳定和肾脏保护效应。

Amyloid-Forming peptide GNNQQNY是由酵母蛋白Sup35的N-末端朊病毒决定结构域中得来的七肽段，具有生物活性，并能形成淀粉样纤维。它的详细原子低聚结构之研究，使其成为揭示早期聚集阶段的理想模型。GNNQQNY二聚体以三种稳定构形存在：寄存器内并排、寄存器外并排和反向并排。对准的平行二聚体其β-pleated sheet结构中肽链间氢键较少，强调了疏水作用的重要性，相较于反向并排结构有更高的构象熵。
