<p>Disclosed is a novel glycoconjugated chlorin derivative which is useful as a substance for photodynamic therapy, is stable, and can act a photosensitizer having high phototoxicity even when used in a small quantity. Also disclosed is a method of producing the derivative. Specifically disclosed are a S-glycosylated chlorin derivative represented by the following general formula (1) and a metal complex thereof. In the general formula (1), X 1 to X 20 independently represent a group selected from the group consisting of F-, sugar-S-, sugar-Z-Sand sugar-O-Z-S- and at least one among X 1 to X 20 represents a group selected from the group consisting of sugar-S-, sugar-Z-S- and sugar-O-Z-S- (wherein F represents a fluorine atom, Z represents an oxygen atom, Z represents a hydrocarbon group having 1 to 6 carbon atoms); and R 5 and R 6 independently represent a hydrogen atom or an organic group or may together form a ring.</p> |
