The present invention pertains to acridone and acridine compounds of formula (I), wherein either: (a) K is ═O, L is —H, alpha is a single bond, beta is a double bond, gamma is a single bond (acridones): or, (b) K is a 9-substituent. L is absent, alpha is a double bond, beta is a single bond, gamma is a double bond and wherein: J
1
is a 2- or 3-substituent; J
2
is a 6- or 7-substituent; J
1
and J
2
are each independently a group of the formula —NHCO(CH
