Capabilities & Facilities
MAC glucuronide phenol-linked SN-38 is a defined ADC Cytotoxin with Linker designed for targeted delivery of SN-38, the active metabolite of irinotecan. This construct uses a glucuronide-based phenol-linked ADC Linker, providing stability in circulation and efficient intracellular release of the ADC payload. As a potent ADC Cytotoxin, it enables selective delivery of SN-38 to antigen-expressing tumor cells, facilitating DNA topoisomerase I inhibition and subsequent apoptosis with controlled release through the cleavable linker.
The mechanism of MAC glucuronide phenol-linked SN-38 relies on antibody-mediated binding to tumor-specific antigens, followed by internalization into malignant cells. Within lysosomes, the glucuronide linker is cleaved by β-glucuronidase, releasing SN-38 directly inside the cell. This selective release ensures the ADC payload exerts its cytotoxic effect specifically in tumor cells, maintaining potent activity while minimizing systemic exposure. The phenol-linked design provides predictable cleavage kinetics and reproducible payload activation.
MAC glucuronide phenol-linked SN-38 allows stable conjugation to monoclonal antibodies, generating homogeneous ADC Cytotoxins with Linker. The glucuronide-based cleavable linker ensures reliable intracellular payload release and preserves the activity of SN-38. Its chemical structure, solubility, and linker stability support consistent ADC assembly, enabling precise intracellular delivery of the cytotoxic agent while maintaining overall ADC integrity.
Applications of MAC glucuronide phenol-linked SN-38 focus on its function as a defined ADC payload-linker combination for constructing homogeneous antibody-drug conjugates. The β-glucuronidase-cleavable linker facilitates controlled release of SN-38 inside tumor cells, producing consistent topoisomerase I inhibition and cytotoxicity. This reagent is essential for generating ADC Cytotoxins with Linker that achieve targeted DNA damage, supporting precision oncology research and development of highly potent, tumor-selective therapeutics.

What is MAC glucuronide phenol-linked SN-38?
MAC glucuronide phenol-linked SN-38 is an ADC payload where SN-38, the active metabolite of irinotecan, is linked via a glucuronide-protected phenol to a macromolecular carrier. This design allows controlled release of SN-38 upon enzymatic cleavage in target cells.

Could you explain how the glucuronide phenol linkage controls SN-38 release?
The glucuronide moiety is cleaved by β-glucuronidase enzymes overexpressed in tumor environments, triggering phenol self-immolation and releasing the active SN-38 molecule selectively within cancer cells.
