一般描述
D-青霉胺来源于相应的 β-内酰胺抗生素的水解。
应用
在肝豆状核变性病中用作抗风湿药和螯合剂。用作铜螯合剂与半胱氨酸或其他硫化物介质组分形成混合二硫化物。用于灭活蛋白-1dna 结合 ，抑制兔关节软骨细胞异步培养的生长 。
生化/生理作用
青霉胺是青霉素类抗生素的特征性降解产物。一个铜原子与两个青霉胺分子结合。青霉胺可减少胱氨酸尿症中过量胱氨酸的排泄。这是通过青霉胺和胱氨酸之间的二硫键互换，形成易于排泄的青霉胺-半胱氨酸二硫化物。青霉胺可干扰原胶原分子之间交联的形成，并在新形成时将其裂解。青霉胺降低 IgM 类风湿因子，抑制 T 细胞活性。
其他说明
将容器密闭保存在干燥和通风良好的地方。

The long-acting antirheumatic drug D-penicillamine was found to inhibit the growth of asynchronous cultures of rabbit articular chondrocytes. This inhibitory effect was dose-related between 5 X 10(-4) M and 5 X 10(-3) M and was time-dependent for a given dose.

Since Pasteur first successfully separated right-handed and left-handed tartrate crystals in 1848, the understanding of how homochirality is achieved from enantiomeric mixtures has long been incomplete. Here, we report on a chirality dominance effect where organized, three-dimensional homochiral suprastructures of
