用途及描述：科研试剂，广泛应用于分子生物学，药理学等科研方面。雷帕霉素（西罗莫司）是新型大环内酯的抗排斥药物，是目前世界上最新的强效免疫抑制剂。本品抑制由抗原和细胞因子（白介素IL-2、IL-4和IL-15）激发的T淋巴细胞的活化和增殖，它亦抑制抗体的产生。在细胞中，西罗莫司与免疫嗜素，即FK结合蛋白-12（FKBP-12）结合，生成FKBP-12免疫抑制复合物。此复合物与哺乳动物的西罗莫司BA分子（mTOR，一种关键的调节激酶）结合并抑制其活性，从而抑制细胞周期中G1期向S期的发展。

Product Description
Macrocyclic-triene antibiotic possessing potent immunosuppressant activity. It forms a complex with FKBP12 that binds to an effector, thus inhibiting IL-2 and other growth promoting lymphokines. The effectors were recently identified as FRAP (FKBP12 rapamycin-associated protein) and RAFT1 (rapamycin and KFBP12target). Rapamycin induces inhibition of p70s6k, p33cdk2 and p34cdc2. Enhances apoptosis.SOURCE/HOST: Isolated from Streptomyces hygroscopicus.
PURITY: 98% (HPLC)
