Compositions and methods related to the treatment of acute kidney injury (AKI) through the pharmaceutical manipulation of calcium signaling are disclosed. Such compositions and methods may be used to reduce inflammatory responses that may lead to AKI, or the progression of AKI to CKD.

The present invention relates to a compound as shown in general formula (I) below (in formula (I), each of R.sub.1 and R.sub.2 independently represents a hydrogen atom or a C1-10 linear or branched alkyl optionally having a substituent, or the two together form a cycloalkyl with 3 to 8 ring carbon atoms; each of R.sub.3 and R.sub.4 independently represents a hydrogen atom or a C1-10 linear or branched alkyl optionally having a substituent or a C6-12 aryl optionally having a substituent, or the two together form a cycloalky with 3 to 8 ring carbon atoms; X represents C or N; and Y represents a linear or branched alkenyl or alkynyl with 2 to 6 carbon atoms and optionally having a substituent, or carboxyl). The compound has good antibacterial properties against bacteria, especially gram-negative bacteria, has low drug resistance, and has good prospects for the effective treatment of various conditions.
