Trisalkylpyridinium porphyrins substituted by one glycosyl (glucosyl, maltosyl, and lactosyl) moiety have been prepared in acceptable yields. These glycosylated cationic porphyrins have been synthesized from pyrrole condensed with 4-pyridinecarboxaldehyde, and suitable ortho- or para peracetylglycosyloxybenzaldehyde derivatives in refluxing propionic acid –Ac2O followed by action of alkyliodide in DMF. Deprotection of the glycosylated moieties led to a new class of representative glycosylated porphyrins. Key words: porphyrins, cationic, glycosylated; phototherapy, cancer.
