| Outline of Final Research Achievements |
We synthesized [65Zn] or [Zn]-5,10,15,20-tetrakis(pentafluorophenyl)porphyrins ([65Zn]-P or Zn-P) bearing two kinds of substituent groups (G2M2), namely glucose group (denoted as G) and 2-mercaptoethanol group (denoted as M) as theranostics drug. The in vitro photocytotoxicity of Zn-PG2M2 was evaluated in HeLa human cervical cell line, RGK gastric carcinoma mucosal cell line, and two human glioblastoma cell lines (U87 and T98G). Zn-PG2M2 exerted the higher photocytotoxicity than fully glucosylated TFPP (G4) at 8 h incubation. From the pharmacokinetics study, the accumulation rate of [65Zn]-PG2M2 in the tumor was about the same as that in digestive organs at 24 h after intraperitoneal injection.
