 | Hazard Information | Back Directory |  | [Description] 
 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.
 |  | [Uses] 
 CL2A-SN-38 is a agent-linker conjugate composed of a potent a DNA Topoisomerase I inhibitor SN-38 and a linker CL2A to make antibody agent conjugate (ADC). CL2A-SN-38 provides significant and specific antitumor effects against a range of human solid tumor types. CL2A-SN-38 uses hydrolyzable linker to deliver active agents within tumor cells and in the tumor microenvironment, resulting in bystander effects[1].
 |  | [in vivo] 
 
 CL2A-SN-38 coupled to the anti-Trop-2 humanized antibody hRS7 (intraperitoneal injection, 0.2 or 0.4 mg/kg, twice weekly, 4 weeks) can both significantly inhibit tumor growth in mice with human colon (COLO 205) or pancreatic (Capan-1) tumour xenografts[2].
