Cerdulatinib hydrochloride

Cerdulatinib hydrochloride (PRT062070) is a selective, oral active and reversible ATP-competitive inhibitor of dual SYK and JAK, with IC50s of 32 nM, 0.5 nM, 12 nM, 6 nM and 8 nM for SYK and Tyk2, JAK1, 2, 3, respectively. Cerdulatinib hydrochloride could be used to research autoimmune disease and B-cell malignancies[1][2].

Cerdulatinib (0.03-4 μM) inhibits ERK Y204 phosphorylation with an IC50 of 0.5 μM and reduces the ability to upregulate cellsurface expression of the early activation marker CD69 with an IC50 of 0.11 μM in B cells in human whole blood[1].Cerdulatinib (0.015-2 μM) inhibits FcεRI-mediated basophil degranulation with an IC50 of 0.12 μM[1].Cerdulatinib (0.5-4 μM) exhibits differential potency against cytokine JAK/STAT signaling pathways[1].Cerdulatinib (0-15 μM; 72 hours) results in viability effects similar to that of the combines SYK plus JAK-selective inhibition[1].Cerdulatinib (1-3 μM; 48 hours) induces apoptosis in BCR-signaling competent non-Hodgkin lymphoma (NHL) cell lines[1]. Cell Viability Assay[1] Cell Line: SU-DHL4; SU-DHL6; Ramosand and Daudi cells

Cerdulatinib (0.5-5 mg/kg; twice daily p.o. for 2 weeks) elicits dose-dependent efficacy in the rat collagen-induced arthritis (CIA) model[1].Cerdulatinib ( mg/kg; twice daily p.o. for 5 days) blocks BCR-induced B-cell activation and splenomegaly in mice[1]. Animal Model: Female Lewis rats (7-8 weeks old; 159-187 g) are immunized[1]
