Abstract: A method of treating coronavirus infection, comprising administering to a subject in need thereof an effective amount of a composition, wherein the composition comprises one or more compounds of Formula (I): or a pharmaceutically acceptable salt thereof.

Abstract: Provided herein is 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 herein 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.
