Abstract

A series of novel chlorophyll-a homologs with long wavelength absorption were synthesized via modification of methyl pyropheophorbide-a used as starting material. For introducing electron-withdrawing group methylenemalononitrile moiety was established on the periphery of modified chlorin by Knoevenagel reaction of malononitrile with formyl group at 3-, 15-position and 13 1-carbonyl group on the exocyclic ring. All of chlorins containing the methylenemalononitrile structure show Qy-absorption at more than 700 nm. Moreover, we have examined a preliminary in vitro photodynamic anticancer effect of these new derivatives on mouse sarcoma S-180 cell line.
