Abstract
The present invention relates to a compound represented by the following general formula (I): R1 and R2 each independently represent a hydrogen atom or an optionally substituted C1-10 linear or branched alkyl, or R1 and R2 together form a cycloalkyl having 3 to 8 ring carbon atoms; R3 and R4 each independently represent a hydrogen atom or an optionally substituted C1-10 linear or branched alkyl, or an optionally substituted C6-12 aryl; or R3 and R4 together form a cycloalkyl having 3 to 8 ring carbon atoms; X represents C or N; and Y represents an optionally substituted linear or branched alkenyl or alkynyl having 2 to 6 carbon atoms, or carboxyl. The compound has good antibacterial activity against bacteria, particularly gram-negative bacteria, low drug resistance, and good prospects for effective treatment of various pathologies.
