USFDA approved protein kinase inhibitors (6 April 2014 Ceritinib) compiled by Robert Roskoski Jr.

Structurea, name, trade name, company, formula, molecular wt. The figures are drawn is such a fashion that the left-most portion of the drug extends toward or into the solvent, and the right side of the molecule interacts with hinge residues and hydrophobic components of target protein kinases, except for everolimus, sirolimus, and temsirolimus which bind to FKBP12 and indirectly inhibit mTOR. All drugs are effective orally, except for temsirolimus which is given intravenously.

aStructures drawn with Accelrys Draw 4.1, Accelrys, Inc. San Diego, CA 92121. In those cases for which the crystal structure of the protein kinase bound to the drug is known, the right side of the molecule occurs in the ATP-binding pocket and the left side of the molecule extends into the solvent. For cabozantinib, dabrafenib, ibrutinib, regorafenib, ruxolitinib, tofacitinib, trametinib, and vandetanib, this mode of binding is inferred, but not experimentally established. 

bD, number of hydrogen bond donors; A, number of hydrogen bond acceptors.

cCalculated log of the partition coefficient; dCalculated log of the distribution coefficient. Both calculations performed with MedChem DesignerTM, version 2.0, Simulationsplus, Inc. Lancaster, CA 93534. The partition coefficient is the ratio of a compounds solubility in octanol/water at pH 7.4. The distribution coefficient is this solubility where pH is not taken into account.

eYear approved Aftatinib, Axitinib, Bosutinib, Cabozantinib, Crizotinib, Dabrafenib, Dasatinib, Erlotinib, Everolimus, Gefitinib, Ibrutinib, Imatinib, Lapatinib, Nilotinib, Pazopanib

fALL, acute lymphoblastic leukemia, CLL, chronic lymphocytic leukemia; CML, chronic myelogenous leukemia; CRC, colorectal cancer; DTC, differentiated thyroid carcinoma; GIST, gastrointestinal stromal tumor; NSCLC, non-small cell lung cancer; RCC, renal cell carcinoma. See the drug label for specifics. For example, one indication for everolimus is for postmenopausal women with advanced hormone receptor-positive, HER2-negative breast cancer in combination with exemestane after failure of treatment with letrozole or anastrozole.
