Abstract

Two new potential magnetic resonance imaging CONTRAST AGENTs, Gd-hematoporphyrin (Gd-H) and Gd-tetra-carboranylmethoxyphenyl-porphyrin (Gd?TCP), were synthesized and applied to nude mice with human MELANOMA (MM?138) xenografts. These agents showed a high relaxivity because of their greater potential to coordinate water molecules. The reduction of T1 relaxation times of 16 and 21% was observed in human MELANOMA tumors grafted in the nude mice 24 h after injection of Gd-TCP and Gd-H, respectively. The percent of injected Gd, that localized to the tumor and measured by inductively coupled plasma atomic emission spectroscopy (ICP-AES), was approximately 21% for Gd-TCP and 28% for Gd-H. A higher concentration of Gd was achieved compared with control indicating selective delivery of Gd-porphyrins to the MELANOMA xenografts. The data indicate that Gd-TCP can be used as a dual probe for diagnosis in MR IMAGING and for therapy in boron neutron capture therapy (BNCT)
