A novel mixed salt of S-[2-[(1-Iminoethyl)amino]ethyl]-2-methyl-L-cysteine is disclosed. The novel mixed salt, S-[2-[(1-Iminoethyl)amino]ethyl]-2-methyl-L-cysteine maleate hydrochloride, may be produced to form crystals that may be arranged as generally orderly packed agglomerates, which are particularly useful in making pharmaceutical compositions. Such pharmaceutical compositions are also described, as well as methods to make crystalline S-[2-[(1-Iminoethyl)amino]ethyl]-2-methyl-L-cysteine maleate hydrochloride, and methods of treating conditions characterized by an overexpression on nitric oxide from the inducible isoform of nitric oxide synthase using the S-[2-[(1-Iminoethyl)amino]ethyl]-2-methyl-L-cysteine maleate hydrochloride.
本发明公开了一种 S-[2-[(1-氨基乙基)氨基]乙基]-2-甲基-L-半胱氨酸的新型混合盐。这种新型混合盐 S-[2-[(1-氨基乙基)氨基]乙基]-2-甲基-L-半胱氨酸马来酸盐酸盐可制成结晶体,结晶体可排列成大致有序的团块,特别适用于制造药物组合物。本文还描述了此类药物组合物,以及制造结晶 S-[2-[(1-氨基乙基)氨基]乙基]-2-甲基-L-半胱氨酸马来酸盐酸盐的方法,以及使用 S-[2-[(1-氨基乙基)氨基]乙基]-2-甲基-L-半胱氨酸马来酸盐酸盐治疗一氧化氮合酶诱导型异构体一氧化氮过度表达的病症的方法。
