MC-SN38 is a drug-linker conjugate that pairs the potent microtubule-disrupting agent SN38 with a non-cleavable MC linker, designed for use in antibody drug conjugates (ADCs). SN38, the active metabolite of the Topoisomerase I inhibitor Irinotecan, works by inhibiting DNA synthesis and inducing DNA single-strand breaks.
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.
MAC glucuronide α-hydroxy lactone-linked SN-38 (Topoisomerase I inhibitor) is a stabilized lactone MAC glucuronide α-hydroxy lactone-linked SN-38 drug linker. MAC glucuronide α-hydroxy lactone-linked SN-38 is cytotoxic across L540cy cells and Ramos cells
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].
