CL2A-SN38 is a SN38 derivative with a Mal-PEG attached peptide linker, it can easily react with antibody to form an antibody-drug conjugate (ADC). SN-38 is a potent DNA Topoisomerase I inhibitor. CL2A-SN-38 provides significant and specific antitumor effects against a range of human solid tumor types. CL2A linker is cleavable through pH sensitivity, giving rise to bystander effect, and binds the antibody at a cysteine residue via a disulfide bond.
