camptothecins

Deruxtecan is an ADC drug-linker conjugate composed of a derivative of DX-8951 (DXd) and a maleimide-GGFG peptide linker used in the synthesis of DS-8201 and U3-1402.

CL2-SN-38, a part of the antibody-drug conjugate (ADC), can conjugate with the anti-Trop-2-humanized antibody hRS7. SN-38 is an inhibitor of DNA topoisomerase I.

Dxd (OQM5SD32BQ) is a potent DNA topoisomerase I inhibitor (IC50= 0.31 μM). Dxd was used as a conjugate drug for HER2-targeted ADCs.

MC-GGFG-DX8951 (MC-GGFG-Exatecan) is an antibody-coupled drug (ADC) drug-linker conjugate (DLC) consisting of DX8951, a potent DNA topoisomerase I inhibitor, the linker MC, and the cleavable peptide chain GGFG, and has antitumor potential.

CL2A-SN-38 consists of a CL2A linker and an anticancer compound, SN-38, which delivers active molecules within tumor cells and in the tumor microenvironment, often in conjunction with antibodies to make biologically active antibody-coupled reactive molecules (ADCs).

MAC glucuronide phenol-linked SN-38, a pH-sensitive lactone and DNA topoisomerase I inhibitor drug linker, exhibits cytotoxicity in L540cy and Ramos cells, with IC50 values of 113 ng/mL and 67 ng/mL, respectively[1].

MAC glucuronide α-hydroxy lactone-linked SN-38 (Topoisomerase I inhibitor) is a cytotoxic drug linker that maintains a stabilized lactone form, demonstrating efficacy against L540cy and Ramos cells with IC50 values of 99 and 105 ng/mL, respectively[1].

CL2E-SN38 TFA, a structurally stable and highly releasable antibody drug conjugate (ADC), comprises SN-38, the active metabolite of Irinotecan derived from camptothecins, known for its Topoisomerase I inhibitory activity.

CL2E-SN-38 is a structurally stable and highly releasable antibody-drug conjugate (ADC) incorporating SN-38, the active metabolite of Irinotecan and a potent Topoisomerase I inhibitor [1] from the camptothecins class.
