Labeling of Tannic Acid with Technetium-99m for Diagnosis of Stomach Ulcer
Keyword(s):
Tannic acid is a polyphenolic compound that could be labeled with technetium-99m. To produce about 90% yield of 99mTc-tannic acid in acidic media (pH), the conditions required were 150 g tin chloride, 30 min reaction time, and 200 g of the substrate. 99mTc-tannic was stable for 6 h. Oral biodistribution of 99mTc-tannic showed that it concentrated in the stomach ulcer to reach about 50% of the total injected dose at 1 h after orall administration. This concentration of 99mTc-tannic in stomach ulcer may be sufficient to radio-image the presence of ulcer in the stomach.
