ABSTRACT
1.-- Synthesis of carcinine was performed by direct condensation of beta-alanine with histamine (free base), in the presence of N-N'-dicyclocarbodiimide. The amine radical of beta-alanine was protected by the t-butoxycarbonyl radical. This fast and simple method yielded a perfectly pure crystalline product. 2.-- Carcinine had no influence upon heartbeat frequency nor on respiratory movements in rats. 3. -- Carcinine had a vasodepressive action upon Vertebrates. It was active at half the concentration of carnosine and at about a thousand times the concentration of histamine. It appeared that histamine lost a great extent of its activity when linked with beta-alanine.
