Novel Synthesis and Properties of Optically Pure N-Trifluoroacetylphenylglycine Hydroxysuccinimide Ester
modification of N-acyl-protected phenylglycine sometimes causes racemization due to the fact that the phenyl ring is directly connected to the α-position of the α-amino acid skeleton. In this report, synthesis and the property of N-trifluoroacetylphenylglycine hydroxysuccinimide ester was archived.
苯甘氨酸是非蛋白质的α-氨基酸,其部分结构存在于一些生物活性化合物中。N-酰基保护的苯甘氨酸的 C 末端修饰有时会导致外消旋化,因为苯环直接连接到 α-氨基酸骨架的 α 位。本报告对N-三氟乙酰苯基甘氨酸羟基琥珀酰亚胺酯的合成及其性质进行了归档。

(R)-(-)- and (S)-(+)-1-(1-[C-11]methyl-1H-pyrrol-2-yl)-2-phenyl-2-(1-pyrrolidinyl)ethanone 4 and 5 were synthesized, and their properties as tracers for positron emission tomography (PET) studies of monoamine oxidase type A (MAO-A) in the brain of living pigs were tested. Parametric maps of the distribution volume (V-d) 4 in pig brain were qualitatively similar to those obtained with [C-11]harmine, with prominent binding in the ventral forebrain and mesencephalon. Its binding was highly vulnerable to MAO blockade, suggesting a binding potential as high as 2 for MAO-A sites. The slow plasma metabolism of 4 and 5 may present advantages over [C-11]harmine for routine PET studies of MAO-A.
