DOTA-bis(tert-butyl)ester 是一种 DOTA 类金属螯合剂,能够与放射性核素结合,而用于制备核素偶联物 (RDC)。DOTA-bis(tert-butyl)ester 可以与不同的盐偶联形成不同的金属螯合剂,例如与 (HY-B1244) 的盐酸盐偶联,得到 DOTA-MN2。DOTA-MN2 可与 [67]Ga-柠檬酸盐反应而获得放射性标记。当 (67)Ga-DOTA-MN2 在磷酸盐缓冲溶液或小鼠血浆中孵育 24 小时不会发生显著分解,在 NFSa 肿瘤小鼠的生物分布实验中具有高肿瘤摄取、迅速的血浆清除,是 SPECT 和 PET 研究的良好材料。

生物活性

DOTA-bis(tert-butyl)ester is a DOTA-based metal chelator that can bind to radionuclides and is used to prepare radionuclide conjugates (RDCs). DOTA-bis(tert-butyl)ester can be conjugated with different salts to form different metal chelators, such as (HY-B1244) hydrochloride to obtain DOTA-MN2. DOTA-MN2 can be reacted with [67]Ga-citrate to obtain radiolabeling. When (67)Ga-DOTA-MN2 is incubated in phosphate buffer solution or mouse plasma for 24 hours, it does not undergo significant decomposition. In the biodistribution experiment of NFSa tumor mice, it has high tumor uptake and rapid plasma clearance, and is a good material for SPECT and PET studies.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
