Cytochrome P450 CYP3A4, human 是一种人工合成的多肽,序列为:Val-Lys-Arg-Met-Lys-Glu-Ser-Arg-Leu-Glu-Asp-Thr-Gln-Lys-His-Arg-Val-Asp-Phe-Leu-Gln(单字母序列为:VKRMKESRLEDTQKHRVDFLQ),分子式为:C113H191N37O34S1,理论分子量为:2644.05Da。
This 21-amino acid peptide corresponds to residues 253-273 of human cytochrome P450 CYP3A4. Cytochrome P450, a family of over a thousand different members, is involved the metabolism of a wide variety of both endogenous and foreign compounds, in drug and toxin removal. In insects, xenobiotic metabolism is known to involve members of the CYP6 family of cytochrome P450s. Cytochromes P450 are thought to facilitate tumor invasion and metastasis by the generation of reactive oxygen species during various metabolic steps and by the activation of protein kinases, cellular proteoglycan changes, and lysosomal enzymes. High cytochrome P450 CYP3A4/5 expression may predict metastasis and poor prognosis in osteosarcomas. Its use as a biomarker of therapeutic response will have implications for the treatment of these tumors.
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。
索莱宝拥有经验丰富的多肽研究团队,以及世界尖端水平的TETRAS自动化多肽合成仪、高效液相色谱仪、液质联用仪等专业设备,确保了研发、生产流程以及产品质量的可靠性严格控制生产流程。索莱宝的多肽研发部门可根据不同应用场景提供目录化产品和定制化解决方案,满足科学研究的多层次、多用途和多样化需求。
