一般描述
半胱胺是一种氨基硫醇，可以还原重要的氧化二硫分子（如胱氨酸）以生成半胱氨酸。
应用
半胱胺可用于广泛的应用中，例如调节基因表达、生长抑素的消耗和纳米颗粒的包被。它可用于研究胱氨酸在代谢异常（如胱氨酸病）中的作用。半胱胺可用作生物传感器开发中的氧化还原敏感成分。
其他说明
氨基硫醇辐射防护剂； 啮齿类动物十二指肠溃疡的诱发剂； 消耗大鼠组织中生长抑素的浓度。

Administration of cysteamine (mercaptoethylamine) induces in rats severe perforating duodenal ulcers. Because the ulcerogenic properties of cysteamine are markedly reduced by treatment with somatostatin, we considered the possibility that cysteamine-induced duodenal ulcer might be mediated by depletion of tissue somatostatin

Cysteamine and its dimeric form cystamine have been applied to the rat striatum by local injection. Both compounds resulted in a dose-dependent decrease of somatostatin levels. Maximal reduction of somatostatin (by about 50%) was obtained at a dose of 50

pH regulates many cellular processes and is also an indicator of disease progression. Therefore, pH-responsive materials often serve as either tools in the fundamental understanding of cell biology or medicine for disease diagnosis and therapy. While gold nanoparticles have broad

Every living cell relies on signal transduction pathways comprised of protein-protein interactions (PPIs). In many cases, these PPIs are between a folded protein domain and a short linear motif (SLiM) within an unstructured region of a protein. As a result
