Abstract:
A method of quenching excited state energy from a photodegradable pigment that has been excited by absorption of light having a wavelength in the wavelength range of 290-800 nm, comprising reacting a pigment with a conjugated fused tricyclic compound having electron withdrawing groups of Formula (II) or a salt thereof: wherein:         A is selected from the group consisting of O, S, C═O, C═S,           B 1 , B 2 , D 1  and D 2  are each independently selected from the group consisting of F, Cl, Br, I, CF 3 , CC13, NR33+, NO2, CN, C(=0)R4, C(═O)OR′, SO2R5, aryl, and —C═CHR6; each m independently is 0, 1, 2, 3, or 4; a is 0 or 1; each R′ is independently selected from the group consisting of LI, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and aryl; R 2  is selected from the group consisting of H, alkyl, cycloalkyl, alkenyl, alkynyl, and aryl; each R 3  is independently selected from the group consisting of H and C 1 -C 6  alkyl; each R 4  is independently selected from the group consisting of H, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and aryl; each R 5  is independently selected from the group consisting of H, O, OH, NH 2 , and Cl; and each R 6  is-independently selected from the group consisting of alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and aryl.

Claim (Index 4):
A method of protecting healthy cells adjacent to cancerous or pre-cancerous cells undergoing photodynamic therapy comprising applying a composition comprising a pigment excited state quencher compound to said adjacent cells to reduce the generation of reactive oxygen species from said healthy cells while the photodynamic therapy generates free radical oxygen from said cancerous or pre-cancerous cells, with a conjugated fused tricyclic compound having electron withdrawing groups of Formula (II) or a salt thereof: wherein: A is selected from the group consisting of O, S, C\u2550O, C\u2550S, B 1 , B 2 , D 1 , and D 2  are each independently selected from the group consisting of F, Cl, Br, I, CF 3 , CCl 3 , NR 3 3 + , NO 2 , CN, C(\u2550O)R 4 , C(\u2550O)OR, SO 2 R 5 , aryl, and \u2014C\u2550CHR 6 ; each m independently is 0, 1, 2, 3, or 4; n is 0 or 1; each R 1  is independently selected from the group consisting of H, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and aryl; R 2  is selected from the group consisting of H, alkyl, cycloalkyl, alkenyl, alkynyl, and aryl; each R 3  is independently selected from the group consisting of H and C 1 -C 6  alkyl; each R 4  is independently selected from the group consisting of H, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and aryl; each R 5  is independently selected from the group consisting of H, O\u2014, OH, NH 2 , and Cl; and, each R 6  is independently selected from the group consisting of alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and aryl.
