Patent ID: 7754684

Claim:
A compound having the chemical structure: wherein: n is 0 or 1; Pt is in a +2 or a +4 oxidation state; wherein; R 1 and R 2 are independently selected from the group consisting of: ═O; H; —C(O)OH; -(1C-6C)alkyl-C(O)OH; —C(O)O − R + ; wherein: R + is selected from the group consisting of Na + and K + ; provided that: when R 2 is ═O, R 1 is not ═O; R 3 is selected from the group consisting of: —R 9 ; -(1C-6C)alkyl-R 9 ; —S(O) 2 R 11 ; R 9 is -(linker)-R 10 , wherein: -(linker) is wherein: a is 2-50; b is 0 or 1; R 10 is selected from the group consisting of: hydrogen; and, a natural, semi-synthetic or synthetic backbone polymer; R 11 is selected from the group consisting of: —R 9 ; -(1C-6C)alkyl-R 9 ; R 4 and R 5 are independently selected from the group consisting of: ammonia; a primary, secondary or tertiary (1C-6C)alkyl amine; a (3C-8C)cycloalkyl amine; an aryl amine; a nitrogen heteroaryl; a nitrogen heteroalicyclic; an aminomethyl nitrogen heteroalicyclic; or, together, as R 4 —R 5 : a 1,2-, 1,3-, 1,4- or 1,5-diamino (2C-8C)alkane; a 1,2- or 1,4- diamino (3C-8C)cycloalkane; a 1,1- or 1,2-di(aminomethyl) (3C-8C)cycloalkane; a 1,1- or 1,2-di(aminomethyl) heteroalicyclic; a di(nitrogen heteroaryl); and a methylene di(nitrogen heteroaryl); if Pt is in the +2 oxidation state (Pt(II)), R 6 and R 7 do not exist; and, if Pt is in the +4 oxidation state (Pt(IV)), R 6 and R 7 are independently selected from the group consisting of —OH, H 2 O, Cl and (1C-6C)alkylC(O)O—.
