SC144 is the first oral active GP130 (IL6-beta) inhibitor. SC144 binds gp130, induces gp130 phosphorylation (S782) and deglycosylation, eliminates Stat3 phosphorylation and nuclear translocation, and further inhibits downstream target gene expression. SC144 inhibited signal transduction induced by GP130 ligand. SC144 induces apoptosis of human ovarian cancer cells.

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

HB0017
HB0017 is a monoclonal antibody that targets interleukin-17 (IL-17) and selectively binds IL-17A, thereby preventing IL-1717A from binding to its receptor. |
Rademikibart
Rademikibart is a human IgG4ҡ monoclonal antibody that targets IL-4 Rα to block inflammatory signaling induced by IL-4 and IL-13, two important cytokines that drive allergic inflammation, and binds to the human IL-4Rα epitope with a KD of 20.7 pM. Rademikibart does not bind to IL-4Rα from other species. Rademikibart does not bind to IL-4Rα of other species.Rademikibart inhibits IL-4 and IL-13-mediated STAT6 signaling, TF-1 cell proliferation, and TARC production in PBMC, and can be used in studies related to moderate-to-severe Th2 inflammatory diseases. |
Stapokibart
Stapokibart is a humanized monoclonal antibody targeting IL-4Rα that blocks the interaction of cytokines IL-4 and IL-13 with their co-receptor subunit, IL-4Rα. Stapokibart is able to interact with IL-4Rα in humans, cynomolgus monkeys, and rats, and can be used in atopic dermatitis research. |
Erepdekinra
Erepdekinra is an interleukin-17A (IL-17A) receptor antagonist. |
