Synthesis and structure–activity relationship for new series of 4-Phenoxyquinoline derivatives as specific inhibitors of platelet-derived growth factor receptor tyrosine kinase
摘要:
We discovered a new series of 4-phenoxyquinoline derivatives as potent and selective inhibitors of the platelet-derived growth factor receptor (PDGFr) tyrosine kinase. We researched the highly potent and selective inhibitors on the basis of both PDGFr and epidermal growth factor receptor (EGFr) inhibitory activity. First, we found a compound, Ki6783 (1), which inhibited PDGFr autophosphorylation at 0.13 muM, but it did not inhibit EGFr autophosphorylation at 100 muM. After extensive explorations, we found the two desired compounds, Ki6896 (2) and Ki6945 (3), which are substituted by benzoyl and benzamide at the 4-position of the phenoxy group on 4-phenoxyquinoline, respectively. These inhibitory activities were 0.31 and 0.050 muM, respectively, but neither of them inhibited EGFr autophosphorylation at 100 M. We further investigated the profile of both compounds toward various tyrosine and serine/threonine kinases. The three compounds specifically inhibited PDGFr rather than the other kinases.

The present invention relates to novel quinoline derivatives and quinazoline derivatives represented by the following formula (I): ##STR1## [wherein R.sub.1 and R.sub.2 are each independently H or C.sub.1 -C.sub.4 -alkyl, or R.sub.1 and R.sub.2 together form C.sub.1 -C.sub.3 -alkylene, X is O, S or CH.sub.2, W is CH or N, and Q is a substituted aryl group or substituted heteroaryl group] and their pharmaceutically acceptable salts, having platelet-derived growth factor receptor autophosphorylation inhibitory activity, to pharmaceutical compositions containing these compounds, and to methods for the treatment of diseases associated with abnormal cell growth such as tumors.
Compounds of the formula ##STR1## in which A is lower alkyl, or a substituted or unsubstituted phenyl, thienyl, furyl, indolyl or thiaindolyl radical, R, X.sub.4 and X.sub.5 are hydrogen or lower alkyl, Y is hydrogen, hydroxy, etherified hydroxy, substituted amino, or N-attached heterocyclyl, X.sub.0 is O or OCH.sub.2 CH.sub.2 O, R' represents hydrogen, lower alkyl or acetyl; and acid-addition salts thereof, are novel and useful in pharmacy as hypolipaemiant, hypocholesterolaemiant and cholagogic agents or in the preparation of such agents.

The invention relates to the preparation of 3-trifluoromethyl- and 2,5-dimethyl-4'-hydroxy-.alpha.-ethyl-benzhydrol. Both compounds have so far been described only as metabolites of corresponding benzhydrol derivatives containing no hydroxyl group. Neither their physico-chemical characteristics nor their manufacturing processes have been disclosed in the known publications. 3-Trifluoromethyl- and 2,5-dimethyl-4'-hydroxy-.alpha.-ethyl-benzhydrol are suitable for the treatment of acute ethanolic intoxication. Accordingly, another aspect of the invention is a pharmaceutical composition containing one of these compounds as active ingredient.
