Synthesis and preliminary evaluation of novel (99m)Tc-labeled folate derivative via click reaction for SPECT imaging

Appl Radiat Isot. 2014 Sep:91:24-30. doi: 10.1016/j.apradiso.2014.04.020. Epub 2014 May 14.

Abstract

The folate receptor is over expressed in a wide variety of human tumors. In this study, a novel (99m)Tc-labeled folate derivative ((99m)Tc-HYNIC-T-FA) was synthesized as a potential FR-targeting imaging probe and its efficiency was evaluated. This (99m)Tc-complex could be obtained through practical manner and showed improved in vivo characteristics compared with other radiofolates. Thus, this novel (99m)Tc-HYNIC-T-FA compound could serve as a potential imaging agent for folate receptor positive tumors.

Keywords: (99m)Tc-labeled folate derivatives; Click chemistry; Folate receptor; KB tumor; SPECT/CT.
