Patent ID: 7205311

Claim:
A compound of the formula: wherein either: (a) K is ═O, L is —H, α is a single bond, β is a double bond, γ is a single bond (“acridone”); or: (b) K is a 9-substituent, L is absent, α is a double bond, β is a single bond, γ is a double bond (“acridine”); and wherein: J 1 is a 2- or 3-substituent; and, J 2 is a 6- or 7-substituent; and wherein J 1 and J 2 are each independently a group of the formula: wherein: R N1 is independently a nitrogen substituent and is hydrogen, C 1-7 alkyl, C 3-20 heterocyclyl, or C 5-20 aryl, and is optionally substituted; and, W is independently C 3-20 heterocyclyl, C 5-20 aryl, and is optionally substituted, or W is independently a group of the formula: —(CH 2 ) n —[G—(CH 2 ) m ] s —T wherein: n is independently an integer from 1 to 8; each m is independently an integer from 1 to 8; s is independently an integer from 0 to 3; each G is independently —O— or —NR N —; each R N is independently a nitrogen substituent; T is independently a terminal amino group, —NR 1 R 2 or a terminal ether group, —OR 5 and wherein, when K is a 9-substituent, K is a group of the formula: wherein: R N2 is independently a nitrogen substituent and is hydrogen, C 1-7 alkyl, C 3-20 heterocyclyl, or C 5-20 aryl, and is optionally substituted; and, Q is independently C 1-7 alkyl, C 3-20 heterocyclyl, or C 5-20 aryl, and is optionally substituted; and pharmaceutically acceptable salts, esters, amides, solvates, and protected forms thereof.
