Abstract [ 99m Tc] fonturacetam hydrazide was radiosynthesized to assess neuropsychiatric disorders by targeting the brain. The nootropic drug labeled with technetium-99m, and factors affecting labeling yield were studied. At optimum conditions, radiocomplex obtained at a high radiochemical (98.9%) stable in saline for up 36 h serum more than 24 h. Labeled characterized assessed silico. Biodist...
