4-（氯甲基）-2,5-恶唑烷二酮

4-（氯甲基）-2,5-恶唑烷二酮是制备环丝氨酸的中间体。Cyclorine是一种抗菌药，可抑制细菌中的细胞壁生物合成。阿昔洛宁还显示出通过影响这些受体上的甘氨酸结合位点而充当NMDA谷氨酸能受体的选择性部分激动剂。

4-(Chloromethyl)-2,5-oxazolidinedione is an intermediate in the preparation of cycloserine. Cycloserine is an antibacterial which functions to inhibit cell-wall biosynthesis in bacteria. Cycloserine has also been shown to act as a selective partial agonist to NMDA glutamergic receptors by affecting glycine-binding sites on these receptors.
