The present invention relates to a compound of formula I wherein X is C(R6) or N, Y is C or N, and ring A, ring B, R1 and R2 have the meanings defined herein, provided that when ring B is carbocyclic, X is C(R6); or a pharmaceutically acceptable salt or solvate thereof. The compounds are tankyrase-1 and tankyrase-2 inhibitors and are useful in the treatment of a number of conditions, including cancer.

A range of 3-oxybenzamide compounds and related quinazolinone compounds are disclosed which can act as potent inhibitors of the DNA repair enzyme poly(ADP-ribose) polymerase or PARP enzyme (EC 2.4.2.30), and which thereby can provide useful therapeutic compounds for use in conjunction with DNA-damaging cytotoxic drugs or radiotherapy to potentiate the effects of the latter. The compounds disclosed include 3-benzyloxybenzamides, 3-oxybenzamides in which a chain of 5 or more methylene groups terminate in a halogen atom or in a purin-9-yl moiety, certain benzoxazole-4-carboxamide compounds and certain quinazolinone compounds. In formula X and Y together may form a bride --X--Y-- that represents the grouping (a), (b) or (c )wherein R.sup.5 is H, alkyl, aryl or aralkyl.

Benzoxazole carboxamides are disclosed which can act as potent inhibitors of the DNA repair enzyme poly(ADP-ribose) polymerase or PARP enzyme (EC 2.4.2.30), and which thereby can provide useful therapeutic compounds for use in conjunction with DNA-damaging cytotoxic drugs or radiotherapy to potentiate the effects of the latter. Representative of the compounds are 2-methyl, 2-t-butyl, 2-phenyl or 2-(4-methoxyphenyl) benzoxazole-4-carboxamide.
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 CH.sub.2 --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. ##STR1##
