Imatinib (STI571) is an orally bioavailable tyrosine kinases inhibitor that selectively inhibits BCR/ABL, v-Abl, PDGFR and c-kit kinase activity. Imatinib (STI571) works by binding close to the ATP binding site, locking it in a closed or self-inhibited conformation, therefore inhibiting the enzyme activity of the protein semicompetitively. Imatinib also is an inhibitor of SARS-CoV and MERS-CoV.

Herbimycin A is an antibiotic and protein tyrosine kinase inhibitor. Herbimycin A directly inhibits the autophosphorylation of p210 BCR-ABL with an IC₅₀ of approximately 5 μM, and reduces Src kinase activity. Herbimycin A also induces the degradation of receptor tyrosine kinases such as insulin-like growth factor 1 receptor (IGF-1R), insulin receptor (IR) and epidermal growth factor receptor (EGFR) via the ubiquitin-20S proteasome pathway. Herbimycin A directly modifies NF-κB p50, with the main target site involving Cys62, thereby blocking the DNA binding of p50 and NF-κB-driven gene expression. Herbimycin A can be used in studies related to tyrosine kinase signaling, chronic myeloid leukemia, NF-κB signaling, osteoclast function, apoptosis and cellular stress.

Embibatinib (TERN-701) is an orally active and allosteric BCR-ABL1 tyrosine kinase inhibitor targeting the myristoyl pocket. Embibatinib exhibits an IC₅₀ of 0.38 nM against ABL1 wild-type enzyme. Embibatinib can be used for the study of chronic myeloid leukemia (CML).

SGX393 (SGX70393) is a Bcr-Abl kinase inhibitor. SGX393 binds to the active conformation of the kinase domains of both wild-type and T315I mutant Bcr-Abl, thereby inhibiting kinase activity. SGX393 exhibits antiproliferative effects in cells expressing wild-type or T315I mutant Bcr-Abl, and suppresses T315I-driven tumor growth. SGX393 can be used for the research of chronic myeloid leukemia.

Bosutinib is an orally active Src/Abl tyrosine kinase inhibitor with IC₅₀ of 1.2 nM and 1 nM, respectively.

Imatinib Mesylate (STI571 Mesylate) is an orally active tyrosine kinases inhibitor that inhibits c-Kit, Bcr-Abl, and PDGFR (IC₅₀=100 nM) tyrosine kinases.

Degrasyn (WP1130) is a cell-permeable deubiquitinase (DUB) inhibitor, directly inhibiting DUB activity of USP9x, USP5, USP14, and UCH37. Degrasyn has been shown to downregulate the antiapoptotic proteins Bcr-Abl and JAK2.

Rebastinib (DCC-2036) is an orally active, non-ATP-competitive Bcr-Abl inhibitor, with IC₅₀ values of 0.8 nM and 4 nM against Abl1^WT and Abl1^T315I, respectively. Rebastinib potently inhibits CYP2C8 (IC₅₀ = 0.0533 μM) and CYP2C9 (IC₅₀ = 2.54 μM). Rebastinib allosterically inhibits Tie2 with an IC₅₀ of 0.63 nM. Rebastinib inhibits the transcriptional activity of FoxO1. Rebastinib inhibits SRC family kinases, KDR and FLT3 kinases. Rebastinib induces Apoptosis. Rebastinib exerts anti-tumor activity in breast cancer. Rebastinib exerts anti-angiogenic effects. Rebastinib increases myotube diameter and improves reduced contractility. Rebastinib can be used in research related to triple-negative breast cancer, luminal breast cancer, pancreatic neuroendocrine tumors, muscle atrophy, cancer cachexia, chronic myeloid leukemia, and B-lymphocytic leukemia.

Naporafenib (LXH254) is a potent, selective, orally active, type II BRAF and CRAF inhibitor, with IC₅₀ values of 0.072 and 0.21 nM against CRAF and BRAF, respectively.

Olverembatinib (GZD824) is a potent and orally active pan-Bcr-Abl inhibitor. Olverembatinib potently inhibits a broad spectrum of Bcr-Abl mutants. Olverembatinib strongly inhibits native Bcr-Abl and Bcr-Abl^T315I with IC₅₀s of 0.34 nM and 0.68 nM, respectively. Olverembatinib has antitumor activity.
