Synonyms: MEDI-6383
Efizonerimod alfa (MEDI-6383) is a recombinant human OX40L IgG4P Fc fusion protein that assembles into a hexameric structure and exerts potent agonist activity upon binding to OX40. The activity of Efizonerimod alfa is enhanced by Fcγ receptor-mediated aggregation. Efizonerimod alfa binds to OX40 on the surface of activated T cells, induces NF-κB promoter activity in OX40-expressing T cells, and triggers the production of Th1-type cytokines, T cell proliferation, and resistance to regulatory T cell (Treg)-mediated suppression. Efizonerimod alfa enhances the cytolytic activity of tumor-reactive T cells and slows tumor growth in immunodeficient mice. Efizonerimod alfa induces the proliferation of CD4, CD8, and B cells in the peripheral blood of healthy non-human primates. Efizonerimod alfa can be used in the research of advanced solid malignancies and melanoma .

Linkers, as key structural units in PROTAC molecules that connect the two functional ends, not only determine the overall molecular conformation and spatial compatibility but also directly influence the stability of the ternary complex, as well as cellular permeability and degradation efficiency. In recent years, with the widespread application of click chemistry in medicinal chemistry, the incorporation of bioorthogonal reactive groups such as azides (-N3) into PROTAC linker design has become an emerging research focus, providing an important tool for modular assembly and rapid structural optimization.

The MCE Azide PROTAC Linker Library contains 0 linkers specifically designed for targeted protein degradation molecule design and optimization. These linkers serve as efficient “click handles,” enabling rapid and highly selective covalent coupling with alkyne reaction partners, thereby facilitating modular assembly and structural diversification of PROTAC molecules. In drug development, this design not only improves the efficiency of molecular construction but also significantly accelerates the screening and optimization of lead compounds. Meanwhile, by tuning linker properties such as length, flexibility, and polarity, the ability to form ternary complexes and degradation activity can be optimized.

Synonyms: Z-VAD(OH)-FMK (Standard)
Z-VAD-FMK (Standard) is the analytical standard of Z-VAD-FMK (HY-16658B). This product is intended for research and analytical applications. Z-VAD-FMK is a pan-caspase inhibitor and also an ICE-like protease inhibitor, which inhibits apoptosis by preventing the processing of CPP32 to its active form. Z-VAD-FMK sensitivity varies primarily due to differential expression of receptor-interacting protein 1 (RIP1). Z-VAD-FMK limits the cryopreservation-induced apoptosis by reducing caspase-3 activity of in vitro produced bovine embryos. Z-VAD-FMK is immunosuppressive in vitro and inhibits T cell proliferation without blocKing the processing of caspase-8 and caspase-3. Z-VAD-FMK leads to a decrease in intracellular glutathione (GSH) with a concomitant increase in reactive oxygen species (ROS) levels in activated T cells. Z-VAD-FMK is due to oxidative stress via the depletion of GSH. Z-VAD-FMK can be used for the study of acute pancreatitis .
