There are described 4-aminobut-2-ynecarboxylic acid derivatives of formula
wherein
R1 and R2are each independently of the other hydrogen, C1-C20alkyl; C3-C12cycloalkyl; unsubstituted or C1-C5alkyl-, C3-C12cycloalkyl-, C1-C5alkoxy-, C3-C12cycloalkoxy-, halo-, oxo-, carboxy-, carboxy-C1-C7alkyl ester-, carboxy-C3-C12cycloalkyl ester-, cyano-, trifluoromethyl-, pentafluoroethyl-, amino-, N,N-mono- or di-C1-C20alkylamino- or nitro-substituted phenyl, phenyl-C1-C5alkyl, naphthyl and naphthyl-C1-C5alkyl; and
R3is C1-C20alkyl; C3-C12cycloalkyl.
The compounds exhibit a pronounced activity against gram-positive and gram-negative bacteria, and also against yeasts and moulds.
这里描述了公式为R1和R2分别独立地为氢、C1-C20烷基、C3-C12环烷基、未取代或C1-C5烷基、C3-C12环烷基、C1-C5烷氧基、C3-C12环烷氧基、卤素、氧代、羧基、羧基-C1-C7烷基酯、羧基-C3-C12环烷基酯、氰基、三氟甲基、五氟乙基、氨基、N,N-单或双-C1-C20烷基氨基或硝基取代的苯、苯-C1-C5烷基、萘和萘-C1-C5烷基的4-氨基丁-2-炔羧酸衍生物,其中R3为C1-C20烷基、C3-C12环烷基。这些化合物对革兰氏阳性和阴性细菌以及酵母菌和霉菌具有显著的活性。
