CL2A-SN-38是drug-linkerconjugate，由linkerCL2A和毒性分子SN-38连接而成的，可用来制备抗体偶联药物。CL2A-SN-38针对人类实体瘤表现出特异性的抗肿瘤作用。SN-38是一种DNATopoisomeraseI抑制剂。CL2A是一种不可降解(non-cleavable)的含PEG8-和三偶氮的PBC-肽-mclinker。CL2A通过pH敏感性降解，产生旁观者效应，并通过二硫键与抗体结合在半胱氨酸残基上。

| 产品描述 | CL2A-SN-38 is a drug-linker conjugate composed of a potent a DNA Topoisomerase I inhibitor SN-38 and a linker CL2A to make antibody drug conjugate (ADC). CL2A-SN-38 provides significant and specific antitumor effects against a range of human solid tumor types. CL2A is a nonclaevable complicated PEG8- and triazole-containing PABC-peptide-mc linker. CL2A is cleavable through pH sensitivity, giving rise to bystander effect, and binds the antibody at a cysteine residue via a disulfide bond[1]. [1]. Cardillo TM, et al.
