The Synthesis of (1,3,4-Oxadiazol-2-yl)Acrylic Acid Derivatives with Antibacterial and Protistocidal Activities

详细

A series of new 1,3,4-oxadiazol-2-yl-acrylic acids was synthesized by cyclization of 4-(2-R-hydrazino)- 4-oxo-2-butenic acids, and their antibacterial and protistocidal activities were studied. The p-substituted benzyl derivatives in the Z-form were shown to exhibit a high protistocidal activity, which exceeded that of the reference drug Baycox (toltrazuril) by several times, whereas the 3-hydroxy-2-naphthyl derivative, in addition to a very high protistocidal activity, also exhibited a moderate antibacterial activity.
