More Information
Summary:Phosphate derivatives are disclosed of quinazolinone compounds having structural formula (I) or a pharmaceutically acceptable salt thereof, wherein X' represent hydroxyl, alkyl, alkoxy, or O-Z where Z is a phosphate or phosphate derivative; Y' represents hydrogen, alkyl or an optionally substituted aryl group or optionally substituted aralkyl group; and R' is hydrogen, alkyl, or CH2-O-Z where Z is again a phosphate or phosphate derivative; subject to the proviso that if neither X' nor R' contains Z, Y' is an aryl or aralkyl group having an O-Z substituent therein with Z once again being a phosphate or phosphate derivative as hereinabove defined. These compounds are useful as prodrugs for providing active PARP inhibiting substances for medical use in conjunction with a cytotoxic drug or radiotherapy in order to increase the effectiveness of the latter, especially in connection with antitumor treatment.
