I. [Product Description]
CCK8-PEG-MTX is a multifunctional organic intermediate constructed by coupling cholecystokinin octapeptide (CCK8) with methotrexate (MTX) through polyethylene glycol (PEG). Its molecular design combines the dual characteristics of targeting peptides and drug carriers. As a pharmaceutical intermediate, this compound is suitable for the development of drug delivery systems. The PEG segment significantly enhances water solubility and circulation stability, and the customizable molecular weight feature can meet the compatibility requirements of different systems.
