Abstract
Labetalol was labeled with 188Re. The reaction conditions (amounts of stannous chloride and substrate, pH, time) were optimized, and the radiochemical yield as high as 95 ± 0.4% was reached. Biodistribution in mice was studied. 188Re-Labetalol showed excellent initial heart uptake and good retention. The heart/liver ratios were 5.16, 2.70, and 2.15 at 30, 60, and 120 min post injection, respectively.
