Btk
Bruton tyrosine kinase
Bruton tyrosine kinase (Btk) is a member of the Tec family kinases with a well-characterized role in B-cell antigen receptor (BCR)-signaling and B-cell activation.
Btk plays a crucial role in B cell development and activation through the BCR signaling pathway and represents a new target for diseases characterized by inappropriate B cell activity. Btk is a kinase expressed exclusively in B cells and myeloid cells and has a well characterized, vital role in B cells highlighted by the human primary immune deficiency disease, X-linked agammaglobulinemia (XLA), which results from mutation in the Btk gene. Btk plays an essential role in the BCR signaling pathway. Antigen binding to the BCR results in B cell receptor oligomerization, Syk and Lyn kinase activation, followed by Btk kinase activation. Once activated, Btk forms a signaling complex with proteins such as BLNK, Lyn, and Syk and phosphorylates phospholipase C (PLC)γ2. This leads to downstream release of intracellular Ca2+ stores and propagation of the BCR signaling pathway through extracellular signal-regulated kinase and NF-κB signaling, ultimately resulting in transcriptional changes to foster B cell survival, proliferation, and/or differentiation.

Terreic acid
0 ImagesTerreic acid, a quinone epoxide antibiotic, acts as an effective Btk inhibitor. Terreic acid blocks the interaction between PKC and the pleckstrin homology domain of Btk. Terreic acid inhibits the binding of GST-BtkPH to PKC in lysates of HMC-1 human mast cells with an IC50 of approximately 100 μM.

PTD10
0 ImagesCat. No.: HY-154860CAS No.: 2642231-19-2PTD10 is a selective and potent BTK PROTAC degrader (DC50 = 0.5 nM, KD = 2.28 nM). PTD10 can recruit cereblon (CRBN) E3 ligase and form a ternary complex with BTK, thereby mediating the ubiquitination and proteasome-dependent degradation of BTK. PTD10 inhibits cancer cells proliferation, and induces cell apoptosis via activation of the caspase-dependent pathway and mitochondrial pathway. PTD10 potently inhibits the BCR, AKT and NF-κB signaling pathway. PTD10 can be used for researches of B-cell malignancies and autoimmune disease.

DBt-10
0 ImagesCat. No.: HY-156746DBt-10 is a PROTAC degrader that targets and degrades BTK by recruiting DCAF1. It degrades BTK in TMD8 BTK-GFP/mCherry cells with a DC50 of 137 nM. DBt-10 induces CRL4DCAF1-dependent ubiquitination and proteasomal degradation of BTK, and retains BTK-degrading and antiproliferative activities in TMD8 cells that are resistant to CRBN-BTK PROTACs due to loss of CRBN expression. DBt-10 has a high survival window and exhibits extremely weak apoptosis-inducing effects on lymphoma cells. DBt-10 can be used for research on diffuse large B-cell lymphoma.
