CL2A-SN-38 DCA 1279680-68-0 (free base)

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 is 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 noncleavable 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. .
