SUBSTITUTED 2-ARYLBENZAZOLE COMPOUNDS AND THEIR USE AS ANTITUMOUR AGENTS

摘要

Substituted 2-phenylbenzazole compounds of formula (I) wherein X represents S or O and Q represents a direct bond, -CH2- or -CH=CH-, exhibit selective antiproliferative activity in respect of mammalian tumour cells. At least in preferred embodiments the benzene ring of the benzazole nucleus has a halogen substituent, preferably fluorine, and the 2-phenyl group has a 4'-amino substituent which may be conjugated with an amino acid to provide a water soluble amino acid amide prodrug or salt thereof.
