In vitro

In human whole blood from normal donors, Cerdulatinib affects BCR-mediated B-cell activation by dual inhibition of SYK and JAK. As a dual SYK/JAK inhibitor, Cerdulatinib significantly reduces cell viability in a subset of NHL cell lines, and induces apoptosis in BCR-signaling competent NHL cell lines. [1]

Immunoblots of MCL-1 and PARP. Following cerdulatinib treatment for 48 hrs at indicated concentrations, MCL-1 and PARP1 cleavage were measured by Western blot in whole cell lysates. GAPDH was included as the loading control.

Immunoblots for early BCR components SYK and BTK following cerdulatinib treatment. Freshly isolated CLL cells (N = 6) were treated with increasing doses of cerdulatinib in the presence of combined stimulation with soluble anti-IgM, CD40L and CpG. p-SYK, total SYK, p-BTK and total BTK were blotted in whole cell extracts.

In vivo In a rat collagen-induced arthritis model, Cerdulatinib (5 mg/kg p.o.) significantly improves inflammatory infiltrate within the synovium and the integrity of the articular cartilage. In addition, Cerdulatinib also blocks BCR-induced B-cell activation and splenomegaly in mice. [1]

Protocol

Kinase Assay:[1]
- Collapse

Purified Kinase Assays:

Potency against purified SYK is determined by fluorescence resonance energy transfer. A broader panel of 270 purified kinases is surveyed in which PRT062070 is tested at a fixed concentration of 300 nM. [33P]-labeled substrate is measured after incubation of purified kinase with peptide substrate and [33P]ATP at the Km concentration for the kinase.
Cell Research:[1]
- Collapse
  • Cell lines: Ramos RA-1, Daudi, Toledo, SU-DHL4 and SU-DHL6 cells
  • Concentrations: ~15 μM
  • Incubation Time: 72 hours
  • Method: Cell lines (Ramos RA-1, Daudi, Toledo, SU-DHL4 and SU-DHL6) are cultured in RPMI media supplemented with 10% fetal bovine serum. Cells are treated with the indicated concentrations of PRT062070, the SYK-selective inhibitor PRT060318, the pan-JAK inhibitor 1, a 1:1 combination of PRT060318 and JAK inhibitor 1, or vehicle control (0.5% dimethylsulfoxide) for 72 hours. Cell viability assays are performed using CellTiter Glo in 384-well plates. Cells are seeded at a density of 5000 cells per well.

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
