Wound healing

A method for promoting wound healing comprising

• applying or administering to a wound site to be treated in an animal an effective amount of phenothiazinium compound of Formula (1);
• and
• optionally exposing the wound site to light,
• wherein:
• each R1-R6 is independently selected from H, optionally substituted C1-6-alkyl, F, Cl, Br and l;
• A and B are independently selected from:
• Q is selected from H and optionally substituted C1-4-alkyl;
• Z is selected from C(Ra)2, O, S, SO2, and NRa in which Ra is selected from H and optionally substituted C1-4-alkyl;
• R7 and R8 are independently selected from optionally substituted C3-6-alkyl delete the phrase;
• Y is a counteranion selected from R−, Br−, CI−, I−, NO3−, SCN−, CIO3−, ClO4−, IO3−, BF4−, HSO4−, H2PO4−, CH3SO4−, N3−, SO42−, HPO42−, PO43−, acetate, lactate, citrate, tartrate, glycolate, glycerate, glutamate, β-hydroxyglutamate, glucouronate, gluconate, malate and aspartate;
• and
• p is 1, 2 or 3,
• in which the optional substituents for any one of R1 to R8, Ra and Q are independently selected from Ph, F, Cl, Br, I, OH, OC1-4-alkyl, CN, OCOC1-4-alkyl, cyclohexyl, methyl-substituted cyclohexyl, cyclopentyl, methyl-substituted cyclopentyl, COOH, COOC1-4-alkyl, and SO3H.
