δ-MSH(TFA盐)

产品介绍

δ-MSH 是一种人工合成的多肽，序列为：Ser-Met-Glu-Val-Arg-Gly-Trp（单字母序列为：SMEVRGW），分子式为：C37H57N11O11S1，理论分子量为：863.99Da。
Delta-MSH is a melanocortin receptor agonist that binds to the melanocortin receptors and stimulates the release of ACTH. It is expressed in tissues such as the dogfish， mouse and human， and has a high affinity for these receptors. Delta-MSH binds to the melanocortin receptors and induces the release of ACTH from the pituitary gland. This compound is also able to stimulate the release of cAMP from cells in tissue culture. The cloning and sequencing of this peptide has revealed that it contains tryptophan residues at cyclic sequences that are involved in its function.
多肽是由两个或多个氨基酸通过肽键连接形成的一类化合物，介于氨基酸与蛋白质之间，是生命活动的核心执行分子之一，其结构可根据氨基酸序列精准调控，适配不同场景的功能需求。
多肽的核心功能围绕生理调节、免疫防御、营养补给与组织修复四大维度展开，每一种多肽的氨基酸序列都决定了其独特的功能特性。在生理调节方面，多肽可作为信号分子参与神经、内分泌、代谢等系统的调控，免疫防御层面，免疫活性肽能刺激淋巴细胞、巨噬细胞增殖，增强机体对病原微生物的抵抗力，抗菌肽可破坏细菌细胞膜，实现广谱抗菌且不易产生耐药性，为机体构建天然防护屏障。同时，多肽还具备优异的抗氧化能力，可清除体内多余自由基，减轻氧化应激对细胞的损伤，延缓衰老进程。
