The present invention relates to salts of formula [A][B], wherein [A] is a cation form of a cycloserine compound and [B] is an anion form of a compound of Formula (I):, wherein the ratio between the cycloserine compound and the compound of formula (I) ranges from 10:1 to 1:10. The salts described herein have improved properties, including greatly increased stability and decreased hygroscopicity. Also provided in the present invention are methods for treating and/or reducing the risk of a neuropsychiatric disorder and/or a bacterial infectious disease (e.g., tuberculosis), comprising administering a subject in need a composition comprising salts of formula [A][B] described herein.本揭示內容關於一種式[A][B]之鹽類，其中[A]為環絲胺酸化合物之陽離子形式以及[B]為式(I)之化合物的陰離子形式：，其中該環絲胺酸化合物及該式(I)之化合物之比例為10：1至1：10。本揭示內容的鹽類具有改良的特性，包含大幅增加的穩定性及減少吸濕性。本揭示內容還提供用於治療神經精神疾病及/或降低該神經精神疾病之風險、或是治療細菌感染疾病(例如結核菌)及/或降低細菌感染疾病之風險的方法，其包含對一有需求之個體投予包含本揭示內容之式[A][B]之鹽類的組合物。
