bruton tyrosine kinase

Remibrutinib (Rhapsido) belongs to small molecule inhibitors and is a highly selective, covalent Bruton's tyrosine kinase (BTK) inhibitor (IC50 = 1 nM) with oral activity and cell permeability. The IC50 for inhibiting BTK activity in blood is 0.23 μM. This compound can be used in research on chronic urticaria.

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

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.

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.

(Rac)-IBT6A is a racemate of IBT6A, an impurity of Ibrutinib that can be utilized in the synthesis of IBT6A Ibrutinib dimer and IBT6A adduct.

Btk Inhibitor 2 (BGB-3111 analog) is a BTK inhibitor.

Tirabrutinib hydrochloride is a potent, highly selective, and irreversible oral BTK inhibitor. Tirabrutinib hydrochloride irreversibly covalently binds to Bruton tyrosine kinase (BTK) in B cells and exhibits potent in vitro cytotoxicity against many types of B cell malignancies, as well as in vivo antitumor activity in mouse models [1].

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

Rilzabrutinib (PRN1008) is a small-molecule inhibitor and a reversible covalent inhibitor of Bruton's tyrosine kinase (BTK) (IC50 = 1.3 nM), featuring high selectivity, oral activity, and favorable cell permeability, exhibiting anti-inflammatory and immunomodulatory activities.

ARQ-531 is a potent and orally active BTK inhibitor with potential antineoplastic activity, with IC50s of 0.85 nM and 0.39 nM for WT-BTK and C481S-BTK, respectively.

BMX-IN-1 (BMX kinase inhibitor) is a selective inhibitor of bone marrow tyrosine kinase on chromosome X (BMX, IC50 = 8 nM) and the related Bruton's tyrosine kinase (BTK, IC50 = 10.4 nM), but BMX-IN-1 is more than 47-656 fold less potent against Blk, JAK3, EGFR, Itk, or Tec activity.

MT-802 is an effective BTK degrader based on PROTAC technology (DC50: 1 nM). MT-802 has the potential to treat C481S mutant chronic lymphocytic leukemia (CLL).

RN486 is an effective and specific BTK inhibitor (IC50: 4 nM).

CNX-774 is a highly specific, irreversible, and orally active BTK inhibitor (IC50<1 nM).

CGI1746 is a potent and highly selective small-molecule Btk inhibitor with IC50 of 1.9 nM.

Spebrutinib (LMK-435) is an orally bioavailable, selective inhibitor of Bruton's agammaglobulinemia tyrosine kinase (BTK), with potential antineoplastic activity.

Avitinib (AC0010), also known as AC0010 or AC0010MA, is an orally available, irreversible, epidermal growth factor receptor (EGFR) mutant-selective inhibitor, with potential antineoplastic activity. Upon oral administration, avitinib covalently binds to and inhibits the activity of mutant forms of EGFR, including the drug-resistant T790M EGFR mutant, which prevents signaling mediated by mutant forms of EGFR. This may both induce cell death and inhibit tumor growth in EGFR-mutated tumor cells. EGFR, a receptor tyrosine kinase that is mutated in a variety of Ys, plays a key role in tumor cell proliferation and tumor vascularization. As this agent is selective towards mutant forms of EGFR, its toxicity profile may be reduced when compared to non-selective EGFR inhibitors, which also inhibit wild-type EGFR.

Pirtobrutinib (LOXO-305) is an advanced BTK inhibitor that displays high selectivity and operates through a non-covalent mechanism. This compound effectively inhibits various BTK C481 substitution mutations, leading to tumor regression in BTK-dependent lymphoma tumors in mouse xenograft models. Furthermore, Pirtobrutinib exhibits remarkable selectivity for BTK, with more than a 300-fold difference compared to 370 other kinases tested. Notably, at a concentration of 1 μM, Pirtobrutinib demonstrates no significant inhibition of non-kinase off-targets.

PCI 29732 is a selective and irreversible Btk inhibitor with IC50 of 8.2 nM in a FRET based biochemical enzymology assay.

BMS-986142 is a potent and highly selective reversible BTK inhibitor (IC50: 0.5 nM).

Branebrutinib (BMS986195) is a potent, covalent inhibitor of Bruton's tyrosine kinase (BTK), >5,000-fold selective over all kinases outside of the Tec family (IC50 <1 nM for BTK).
