Octapeptide-2 主要作用于皮肤细胞，它能够与细胞膜上的特定受体结合，激活细胞内的相关信号通路。 研究发现，它可调节细胞内的钙离子浓度，影响蛋白激酶的活性，从而促进胶原蛋白和弹性蛋白的合成，增强皮肤的紧致度和弹性。

虽然 Cholecystokinin Octapeptide (1-2) (Desulfated) 只是 CCK 八肽的一个片段，但对其研究也能侧面反映 CCK 相关功能机制。 消化系统方面：CCK 最初从猪肠黏膜分离出来，在哺乳动物消化系统中，它能刺激胰腺外分泌分泌、胆囊收缩和肠道蠕动 。

这意味着，八肽2A (Octapeptide 2A) 在调控这些关键基因的表达方面，可能比其前体分子丁香菌素A (Syringafactin A) 更为有效。 这个发现如同揭示了一个 ...

Two-octapeptide repeat region (2-OPRD) deletions were reported in two unrelated patients and were considered to be pathogenic (6, 30). The two 2-OPRD cases were characterized by late age of onset (86 ...

The steady increase of antimicrobial resistance (AMR) represents a global threat (1). The identification of new compounds with novel binding sites to circumvent cross-resistance is a central aspect in ...

A new cyclic octapeptide, named clausenain B, was isolated by a multi-step chromatography procedure from Clausena anisum-olens. Its structure was established as cyclo (-Phe 1 -Ser-Leu 1 -Phe 2 -Phe 4 ...
