  摘要：

  为了合成 2-氨基-3-[(1, 2-二羧乙基)硫]丙酸（ADC）的四种立体异构体，以 (1S, 2S)-2- 氨基-1-苯基-1, 3-丙二醇和 (R)- 和 (S)-1- 苯乙胺为分辨剂，对 (RS)-巯基丁二酸[(RS)-MSA]进行了光学分辨，得到了光学纯度为 100%的 (R)- 和 (S)-MSA 。此外，根据熔点、溶解度、红外光谱以及二元和三元相图，研究了(RS)-MSA 的 1-丙基铵盐和 1-丁基铵盐的外消旋结构，目的是通过(RS)-MSA 的优先结晶实现光学分辨。结果表明，(RS)-MSA 的 1-丁基铵盐[(RS)-BA 盐]以团聚体形式存在，而 1-丙基铵盐则形成外消旋化合物。通过对(RS)-BA 盐的优先结晶进行光学解析，得到了光学纯度超过 90% 的(R)-和(S)-BA 盐。通过光学解析得到的(R)-和(S)-MSA 与(R)-和(S)-2-氨基-3-氯丙酸盐酸盐缩合，得到(2R, 1'R)-、(2S, 1'S)-、(2R, 1'S)-和(2S, 1'R)-ADC。此外，这些立体异构体也是由 D-和 L-半胱氨酸以及光学活性溴代丁二酸合成的。

  A compound represented by formula (I) is provided, wherein in formula (I), R 1 and R 2 each independently represents hydrogen, O—R 3 or S—R 4 , at least one of R 1 and R 2 is O—R 3 or S—R 4 , and R 3 and R 4 are independently a C 1 to C 10 alkyl group, such that the C 1 to C 10 alkyl group is non-substituted or substituted with at least one selected from the group consisting of —OH, —NH 2 , halogen, ester, ether, and carboxylic acid, and M being a metal or a metal-containing compound. The compound represented by formula (I) is shown to have higher specificity to tumor cells, and is therefore suitable for carrying anti-cancer drugs and/or nuclear imaging agents.

  An antagonist of NMDA-sensitive glutamate receptors in rat brain membrane and rat spinal motoneurones was isolated from Amanita pantherina and ideneified as a diastereoisomeric mixture of 2-amino-3-(1, 2-dicarboxyethylthi)propanoic acids. The mixture was separated and the absolute configurations of the components were determined as (2R), (1'R) and (2R), (1'S), by analysis of the properties.
