Claim:
A compound having any one of the following structures: wherein: X=—NR 1 R 2 , where R 1 and R 2 are selected from the group consisting of —H, —C 1 through —C 12 alkyl, phenyl, substituted phenyl, —R′NH 2 , and —R′—NH—R″, where R′ and R″ are alkyl groups including straight chain and branched groups, as well as cycloalkyl, and where X may also equal prolinyl, imidizoyl, pyrrolyl, or pyridyl, where these groups are bonded at N; Y=—H, —C 1 through —C 12 alkyl, phenyl, substituted phenyl, —OR′, or —NR′R″, where R′ and R″ are alkyl groups including straight chain and branched groups, as well as cycloalkyl; and R 1 –R 7 =—H, —C 1 through —C 12 alkyl, phenyl, substituted phenyl, —OH, —OR′, —O(CH 2 CH 2 O) n H, where n=1–12, —NH 2 , —NR′R″, —SH, —SR′, —R′CO 2 H, —R′CO 2 R″, —OR′CO 2 H, —OR′CO 2 R″, C(O)H, C(O)R 1 , or CH 2 OH, where R′ and R″ are alkyl groups including straight chain and branched groups, as well as cycloalkyl, and where R 1 –R 7 may also equal any sugar or carbohydrate where this group is bonded at O.
