IBT6A, an impurity of Ibrutinib, is a Btk inhibitor (IC50: 0.5 nM) that can be utilized in the synthesis of IBT6A Ibrutinib dimer and IBT6A adduct.

Rilzabrutinib (PRN1008) is a reversible covalent, selective, and orally active inhibitor of Bruton's Tyrosine Kinase (BTK) with an IC50 of 1.3 nM.

Evobrutinib(M2951) , also known as M-2951 and MSC-2364447C, is a highly selective inhibitor of the Bruton's tyrosine kinase (BTK), which is important in the development and functioning of various immune cells including B -lymphocytes and macrophages. PreClinical research suggests it may be therapeutically useful in certain autoimmune diseases.

Acalabrutinib (ACP-196), also known as ACP-196, is an orally available inhibitor of Bruton's tyrosine kinase (BTK) with potential antineoplastic activity. Upon administration, ACP-196 inhibits the activity of BTK and prevents the activation of the B-cell antigen receptor (BCR) signaling pathway. This prevents both B-cell activation and BTK-mediated activation of downstream survival pathways. This leads to an inhibition of the growth of malignant B cells that overexpress BTK. BTK, a member of the src-related BTK/Tec family of cytoplasmic tyrosine kinases, is overexpressed in B-cell malignancies; it plays an important role in B lymphocyte development, activation, signaling, proliferation and survival.

Atuzabrutinib (SAR 444727) is a selective Bruton's tyrosine kinase (Btk) inhibitor that inhibits intra-neutrophilic neutrophilic granulocytes through inhibition of the adhesion receptor signaling pathway, and can be used to study autoimmune disorders such as arthritis in rheumatoid rodents and pemphigus vulgaris.

Orelabrutinib (ICP-022) is an orally active and irreversible inhibitor of Bruton's tyrosine kinase (BTK).

Tyrosinase-IN-16 inhibited tyrosinase.

Ibrutinib (PCI-32765) is an irreversible inhibitor of BTK (IC50: 0.5 nM) that selectively blocks B cell activation.
