Description

DESCRIPTION

FUSED HETEROCYCLIC COMPOUND Technical Field

The present invention relates to a fused pyrimidine compound having a growth factor receptor tyrosine kinase inhibitory activity, which is useful for the prophylaxis or treatment of cancer, a production method thereof and use thereof.

Background of the Invention

The gene of cell growth factor and growth factor receptor is called a protooncogene and plays a key role in the pathology of human tumor. The epithelial cell growth factor receptor family (erbB) includes EGFR, HER2, HER3 and HER4, which are type I receptor type tyrosine kinases. These erbB family express in various cell groups, and are deeply involved in the control of the growth and differentiation of cells and the control of suppression of cell death (apoptosis suppression) . For example, high expression of EGFR and HER2, and homeostatic activation of receptors are empirically known to transform cells.

It is also known that high expression and simultaneous expression of each of these receptors are poor prognostic factors in various cancer patients.

These receptors are bound with many peptide ligands such as EGF, TGFQ_C and the like, and binding of the ligand promotes homo- or heterodimerization of the receptors. This induces increase of kinase activity from self-phosphorylation or transphosphorylation of the receptors, and causes activation of downstream signaling pathway (MAPK, Akt) via a protein bound with a particular phosphorylated tyrosine residue. This is the substance of the receptor activity of the above- mentioned cell growth, differentiation, cell death suppression and the like_/ which is considered to be responsible for the high expression of receptor in cancer and malignant degeneration of cancer due to topical increase in the ligand concentration. Many cancers are associated with the high expression of EGFR or HER2. For example, breast cancer (20-30%), ovarian cancer (20-40%), non-small cell lung cancer (30-60%), colorectal cancer (40-80%), prostate cancer (10-60%), bladder cancer (30-60%), kidney cancer (20-40%) and the like can be mentioned. Moreover, receptor expression and prognosis are correlated, and receptor expression is a poor prognostic . factor in breast cancer, non-small cell lung cancer and the like. In recent years, clinical use of a humanized anti-HER2 antibody (Trastuzumab) against HER2 highly expressing breast cancer, clinical, trial of anti-EGFR antibody and clinical trials of several low molecular weight receptor enzyme inhibitors have demonstrated a potential of these drugs against HER2 or EGFR for therapeutic drugs for cancer. While these drugs show a tumor growth inhibitory action in clinical and nonclinical trials, they are known to induce inhibition of receptor enzyme activity and suppression of downstream signaling pathway. Therefore, a compound inhibiting EGFR or HER2 kinase, or inhibiting activation of EGFR or HER2 kinase is effective as a therapeutic drug for- cancer .

As a compound that inhibits receptor type tyrosine kinases including HER2/EGFR kinase, fused heterocyclic compounds (e.g., WO97/13771, WO98/02437, WO00/44728, WOOl/ 19828 , WO2005/ 118588 ) , quinazoline derivatives (e.g., WO02/02552, WO01/98277, WO03/049740, WO03/050108) , thienopyrimidine derivatives (e.g., WO03/053446) , aromatic azole derivatives (e.g., WO98/03648, WO01/77107, WO03/031442) and the like are known; however, ^' there is no HER2 kinase inhibitory substance to the present that has been marketed as a therapeutic drug for cancer.

A suspension of human breast cancer cell BT-474 (100 μl (6,000 cells)) were plated to 96-well microplate and cultured in an incubator (37°C 5% carbon dioxide) . On the following -day, 100 μl of a solution of each test compound previously diluted serially in 2-fold, was added to give indicated dose, and the cells were cultured for 5 days. The culture medium containing the test compound was removed, and the cells were washed, and fixed with 50% trichloroacetic acid, and 0.4%. (w/v) SRB solution

(dissolved in 1% acetic acid) was added to stain the cell protein (Skehan et al . , Journal of the National Cancer Institute, Vol. 82, pp. 1107-1112, 1990). After washing with a 1% acetic acid solution, 100 μl of Tris solution (10 mM) was added to extract the pigment and the absorbance was measured at a wavelength of 550 nm to quantify the amount of cells as protein content. Taking as 100% the protein content for the control group, which received no test compound solution, the ratio of the residual protein content for each treatment group was determined, and the compound concentration required to achieve 50% suppression of the residual cell content relative to the control (IC₅₀ value) was calculated. The results are shown in Table 3.
