18F radiolabeled phenylpyridine derived from stable pharmacological synthesis of cough precursors and these precursors

摘要

It refers to a radioactive weapon component, including: (a) the effective amount of a radiolabeled 18F compound, as a phenylpyridine or dihydrohydrazine derivative, which is ((E) - 4 - (2 - (6 - (2 - (2 - (2 - [18F] fluoroetoxi) etoxi) pyridine-3-il - (ethylene) - N-methylaniline and (2R, 3R), (11br) - 9 - (3 - [18F] fluoropropane) - 3-isopropyl-10-methyl-11b-methyl-2,3,4,6,7,11b-hexahydro-pyridine [2,1-a] isoquinine-2-ol; b) the proportion of ethanol in the total composition is 1-15% (V / V);(c) ascorbic acid salts of 0.1% to 1% (P / V) or salts in their total constituents. The pH value of the radioactive weapon component is between 4.5-8.0, which is an effective means to obtain scanning images of n-propene (PET) release from brain neurodegenerative diseases. In this case, pathological targets include abnormal concentrations of protein, cucumber or oligoribose, such as b-amiloude, a-sinucleina, 1. Monoamine water truck
