Abstract
Abstract The invention relates to 8-aminoalkylpsoralens, having essentially no erythematic photosensitizing activity but at the same time having substantial DNA-binding photosensitizing activity, making them of especial interest from the standpoint of suntanning and psoriasis treatment, characteristics which are unpredictable when the compounds are compared with psoralens of similar but different structure.
