The present invention provides a compound having the structure: ##STR00001##
and use of the compound for inhibiting the growth of or killing

This invention relates to agents that are inhibitors or activators of variant forms of endogenous proteins and novel methods of identifying such variants. Of particular interest are inhibitors and activators of endogenous protein variants, encoded by genes which have mutated, which variants often arise or are at least first identified as having arisen following exposure to a chemical agent which is known to be an inhibitor or activator of the corresponding unmutated endogenous protein.

Compound of formula I: ##STR00001##
wherein: A is selected from: (i) ##STR00002##
where R.sup.F1 is H or F; (ii) ##STR00003## (iii) a N-containing C.sub.6 heteroaryl group; and B is ##STR00004##
where X.sup.1 is either CR.sup.F2 or N, where R.sup.F2 is H or F; X.sup.2 is either CR.sup.3 or N, where R.sup.3 is selected from H, Me, Cl, F OMe; X.sup.3 is either CH or N; X.sup.4 is either CR.sup.F3 or N, where R.sup.F3 is H or F; where only one or two of X.sup.1, X.sup.2, X.sup.3 and X.sup.4 may be N; and R.sup.4 is selected from I, optionally substituted phenyl, optionally substituted C.sub.5-6 heteroaryl; optionally substituted C.sub.1-6 alkyl and optionally substituted C.sub.1-6 alkoxy, which are useful in the treatment of a condition ameliorated by the inhibition of MOZ.
