Commercial reagents and solvents were purchased from Sigma-Aldrich (St. Louis, MO, USA), Wako Pure Chemical Industries (Osaka, Japan), Nacalai Tesque, Inc., (Kyoto, Japan), Tokyo Chemical Industry, Co., Ltd., (Tokyo, Japan), and Macrocyclics (Dallas, TX, USA). All of these were used without further purification unless otherwise stated.
[
67Ga]GaCl
3 and [
123I]BMIPP were supplied by Nihon Medi-Physics Co., Ltd. (Tokyo, Japan). The radioactivity was measured by an
Auto Gamma System ARC-7010B (Hitachi, Ltd., Tokyo, Japan).
Proton nuclear magnetic resonance (
1H-NMR) spectra was recorded on
JEOL JNM-ECS400 (JEOL Ltd, Tokyo, Japan). Figures of the NMR spectra are available in the Supplementary Material file (
S6 Fig). Electrospray ionization mass spectra (ESI-MS) were obtained with JEOL JMS-T100TD (JEOL Ltd). TLC analysis was performed using silica plates (
Art 5553, Merck, Darmstadt, Germany).
