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.

NRX-0492
0 ImagesNRX-0492 is an orally active BTK PROTAC degrader, with a binding IC50 of 1.2 nM for both wild-type BTK and BTKT474I, and 2.7 nM for BTKC481S, and exhibits cellular DC50 values of 0.1 nM and 0.2 nM against wild-type BTK and BTKC481S, respectively. NRX-0492 catalyzes the ubiquitination and proteasomal degradation of wild-type and drug-resistant mutant BTK by recruiting the CRBN E3 ubiquitin ligase complex. NRX-0492 inhibits the BCR signaling pathway and its downstream NF-κB/MYC transcriptional program, achieves rapid and sustained degradation in primary CLL cells, and exhibits extremely low cytotoxicity. NRX-0492 degrades BTK, inhibits tumor cell proliferation and activation, and significantly suppresses tumor growth in xenograft models. NRX-0492 can be used in research related to chronic lymphocytic leukemia and diffuse large B-cell lymphoma.

L18I
0 ImagesL18I is a Bruton's tyrosine kinase (BTK) PROTAC degrader that targets wild-type and BTKC481, and recruits the cereblon E3 ligase to mediate proteasomal degradation. L18I regulates the BCR, TLR, FcγR and NLRP3 inflammasome signaling pathways, inhibits the phosphorylation of PLCγ-2, ERK1/2 and p38, and reduces the levels of B cell activation markers CD25, CD69 and CD86. L18I downregulates the NF-κB, TNF and TLR signaling pathways, reduces the production of pro-inflammatory cytokines, and decreases immune cell infiltration and immune complex deposition. L18I inhibits the proliferation of BTK-expressing lymphoma cells, induces tumor regression in xenograft models, and exhibits synergistic activity when combined with inhibitors of SYK, PI3K or Lyn. L18I can be used in research related to lupus, diffuse alveolar hemorrhage and B-cell lymphoma.

Flixebrutinib
0 ImagesSynonyms: TL-895Flixebrutinib (TL-895) is a potent, orally active, ATP-competitive, and highly selective irreversible BTK inhibitor. Flixebrutinib is active against recombinant BTK (average IC50: 1.5 nM) and inhibits only three additional kinases BLK, BMX (IC50 = 1.6 nM) and TXK with IC50 within tenfold of BTK activity. Flixebrutinib inhibits BTK auto-phosphorylation at the Y223 phosphorylation site (IC50: 1-10 nM). The Flixebrutinib effectively inhibits the production of inflammatory factors such as IL-8, IL-1β, MCP-1 and TNF-α by monocytes or macrophages, and reduces the chemotactic migration of MF cells towards SDF-1. Flixebrutinib is used be for studies of chronic lymphocytic leukemia (CLL), myelofibrosis (MF), and B-cell malignancies.
