Summary: Bruton's tyrosine kinase (BTK), an indispensable intracellular signaling element in immune pathways, has been targeted for inhibition with covalent reversible inhibitors. PRN473 and rilzabrutinib have shown potent and durable inhibition of BTK, demonstrating clinical efficacy in canine pemphigus foliaceus.

Summary: This study reveals new mutations in the BTK kinase domain and occasional mutations in downstream PLC gamma 2 in patients with chronic lymphocytic leukemia who developed resistance to the noncovalent BTK inhibitor pirtobrutinib. Despite the inactivity of BTK, alternative pathways of B-cell-receptor signaling were evident.

Summary: Understanding the B cell receptor pathway and the development of targeted BCR inhibitors, such as ibrutinib, has transformed the treatment of CLL. However, many patients discontinue treatment due to adverse events. Zanubrutinib, a second-generation BTK inhibitor, shows promising efficacy and tolerability in early phase clinical trials.

Summary: Multiple myeloma remains an incurable disease despite advancements in treatment, leading to aggressive relapses in patients. The cytosolic kinase BTK plays a crucial role in the survival of malignant clones and multiple myeloma stem cells, making it a promising therapeutic target. Inhibition of the BTK pathway may disrupt interactions between malignant clones and the bone marrow microenvironment in MM patients.

Summary: This study compared the efficacy of the phytochemical kinase inhibitor withaferin A with the clinically approved BTK inhibitor ibrutinib in targeting hyperactivated tyrosine kinase signaling in glucocorticoid-resistant multiple myeloma cells. The results showed that withaferin A was more effective in killing BTK-overexpressing glucocorticoid resistant MM1R cells than ibrutinib. Overall, withaferin A's promiscuous inhibition of multiple BTK family tyrosine kinases represents a highly effective strategy to overcome glucocorticoid therapy resistance in multiple myeloma.

Summary: In this study, machine learning techniques were used to build classification models for predicting the bioactivity of non-covalent inhibitors of BTK. Data on BTK inhibitors were collected and processed, and different fingerprints and machine learning algorithms were utilized to construct the models. The best model achieved high accuracy and MCC on the test set. Additionally, interpretability was provided through the SHAP method and visualization techniques. The study’s results were validated using crystal structures, and the models showed promise in guiding the design of new BTK inhibitors.

Summary: Therapy based on Bruton's tyrosine kinase (BTK) inhibitors is a major treatment option for lymphoma patients, with the first generation showing remarkable progress but still facing issues like drug-resistance and serious side effects. New BTK inhibitors have been developed to address these challenges and their effects on immune-related diseases are being evaluated in clinical trials. Progress in the research and development of BTK inhibitors, focusing on structural characteristics and structure-activity relationships, has been summarized in this review.

Summary: T and B cell receptor signaling activates Akt, MAPKs, PKC, intracellular Ca2+, and calmodulin. This process involves Src and the phosphorylation of Cx43 residues Y247, Y265, and Y313 by BTK and ITK. Overexpression of BTK or ITK leads to increased Cx43 phosphorylation and decreased gap junction communication in HEK-293T cells. Activation of B cell receptor or T cell receptor enhances BTK and ITK activity, resulting in decreased Cx43 phosphorylation and altered gap junction function.

Summary: BI 705564 demonstrated good safety, pharmacokinetics, and pharmacodynamics in clinical trials, with efficient target engagement and proof of mechanism shown through effects on allergic skin responses. Mild bleeding-related adverse events were observed, likely due to inhibition of platelet aggregation by BTK inhibition.

Summary: The study suggests that the combination of HSP90 inhibitor ganetespib with BTK inhibitor ibrutinib may be an ideal approach for MCL treatment, as it enhances the effects of ibrutinib on MCL cells by promoting cell cycle arrest, inducing cell apoptosis, increasing DNA damage, and inhibiting tumor growth.

Summary: The study demonstrates that TLR2/TLR6 agonists can activate human platelets, inducing functional responses and increased adhesion to endothelial cells. The findings suggest that TLR2-mediated signaling plays a crucial role in platelet activation, potentially serving as a druggable target to reduce excessive platelet activation in thrombo-inflammatory diseases.
