Synthesis of 131I derivatives of indolealkylamines for brain mapping
摘要:
The synthesis and spectral properties of new radioiodinated indolealkylamines like 2-[I-131]-iodo-N,N-dimethyltryptamine, 2-[I-131]-iodo-N-methyltryptamine, 2-[I-131]-iodo-5-methoxy-N,N-dimethyltryptamine, 2-[I-131]-iodo-5-hydroxy-N,N-dimethyltryptamine (2-[I-131]-iodo-bufotenine), and 2-[I-131]-iodo-tryptamine and the known 2-[I-131]-iodo-N-acetyl-5-methoxy-tryptamine (2-[I-131]-iodo-melatonine) are described herein. These were synthesized by a high-yield novel method, and their spectral properties are fully described. These compounds are of biological importance and can be used for brain mapping with SPECT technology.
