Patent ID: 7642280

Claim:
A compound having Structure I: wherein each of x and y independently has the value of 0 or 1, and each of X 1 and X 2 is —O(CH 2 ) m Q, wherein m=1-4 and wherein Q is selected from the group consisting of —NH 2 , —NH(CH 2 ) s CH 3 , —N[(CH 2 ) s CH 3 ] 2 , —N + [(CH 2 ) s CH 3 ] 3 , and —(CH 2 ) s NH 2 , wherein s=0-3, n=1-6, and r=0-4; W is selected from the group consisting of —H and —OH; wherein each of R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 is independently selected from the group consisting of —H, —CH 3 , and —(CH 2 ) p CH 3 , wherein p=0-3, R 4 is optionally present and —CHR 2 and R 3 can join to become —C═CR 7 , forming an imidazole ring, and then R 7 is selected from the group consisting of: H, wherein each of X 5 , X 6 , and X 7 is independently selected from the group consisting of —H, —F, —Cl, —Br, —I, —OH, —OCH 3 , —NH 2 , —CONH 2 and —O(CH 2 ) m Q, wherein m=1-4 and wherein Q is selected from the group consisting of —NH 2 , —NH(CH 2 ) s CH 3 , —N[(CH 2 ) s CH 3 ] 2 , and —N + [(CH 2 ) s CH 3 ] 3 , wherein s=0-3, n=1-6, and r=0-4; and wherein R 9 is selected from the group consisting of —H, CH 3 , and (CH 2 ) s CH 3 , wherein s=0-3, and pharmaceutically suitable salts thereof.
