Synthesis and anticancer activities of porphyrin induced anticancer drugs

In view of the property of porphyrin's accumulation selectively in tumor, the ftorafur was modified by binding a porphyrin block to improve its tumor targeting and reduce its side effects. These novel porphyrin derivatives and metal compounds were synthesized under mild conditions with satisfactory yield, and the constructions of all these new compounds were characterized by UV, IR, MS, 1H NMR spectra and elementary analysis. Their anticancer activities were evaluated by MTT assay; the results indicated that the anticancer activities of compounds 4a-c were twice as high as that of ftorafur.
