Enantiomeric pairs of the title compounds were synthesized starting from (S)-and (R)-pyroglutamic acid. They were found to be susceptible to nucleophilic ring opening of aziridine moieties and to exhibit weak in vitro cytotoxicity.
                                    以(S)-焦谷
氨酸和(R)-焦谷
氨酸为起点,合成了标题化合物的对映体。研究发现,它们易受
氮丙啶分子的亲核开环作用影响,体外细胞毒性较弱。
