实验参考方法

Cell experiment:

Cells are incubated in serum-free RPMI media for 1-1.5 hours. Isolated human B cells are incubated with Spebrutinib at a final concentration of 0.001, 0.01, 0.1 and 1 μM. Ramos cells are incubated with 0.1 nM-3 μM Spebrutinib. Cells are then incubated in the presence of compound for 1 hour at 37°C. Following incubation, cells are centrifuged and resuspended in 100 μL of serum-free RPMI and BCR is stimulated with addition of 5 μg/mL α-human IgM. Samples are centrifuged, washed in phosphate-buffered saline (PBS), and lysed in 100 μL of Cell Extraction Buffer plus 1:10 (v/v) PhosSTOP Phosphatase Inhibitor and 1:10 (v/v) Complete Protease Inhibitor. Antibodies used for immunoblot analysis include P-PLCγ2, PLCγ2 (3871; CST), Syk (2712; CST), P-Syk (2710; CST), Btk, P-Btk, and Tubulin. Membranes are scanned on a Li-Cor Odyssey scanner using infrared fluorescence detection[1].

产品描述

CC-292, formerly known as AVL-292, is an orally active, potent irreversible small molecule inhibitor of BTK with IC50 of 0.5 nM and EC50 of 8 nM. [1]
The B cell receptor (BCR) signaling pathway plays an important role in the fate and function of B cells by modulating cellular selection, maturation, proliferation, and production of antibody.
BTK, which is a tyrosine kinase member of the Tec kinase family, is a unique therapeutic target among kinases in the pathway BCR signaling. Studies showed that loss of gene function mutations of BTK in humans consequently leads to X-linked agammaglobulinaemia (XLA), characterized by a complete lack of B cells, low concentrations of serum Ig, and recurring infections, which implies that BTK is required in the development and immunoglobulin production of B cells. CC-292 inhibits BTK by the formation of a covalent bond with Cys481 residue. [2]
The inhibitory activity of CC-292 has been examined in immunoblot analysis, which showed that CC-292 potently inhibits auto-phosphorylation in human naive primary B cells. Furthermore, CD69 upregulation tested by flow cytometry tracking also exhibited a dose-dependent reduction in CD69 expression with increasing levels of CC-292 in vitro. Covalent probe analysis of human B cells coupled with enzyme linked immunosorbent assay (ELISA) quantification methods illustrated 42% BTK occupancy in a 1h incubation with CC-292 of 10 nM. [1, 2]
Studies in vivo for CC-292 has been conducted. CIA model in mice was orally treated with CC-292, which demonstrated a positive correlation between BTK occupancy and inhibition of the disease. In addition, CC-292 was assessed with clinical trials, which showed a T1/2 of 1.9h and suggested efficacy in B-NHL, WM, and CLL patients. [2]
