Anthelmintic and antibacterial screening of a new series of N-[4-(4-nitrophenoxy)phenyl]-4-(substituted)-1,3-thiazol-2-amines

A series of N-4-(4-nitrophenoxy)phenyl]-4-(substituted)-1,3-thiazol-2-amines was synthesized. Structural elucidation was accomplished by ¹H NMR, ¹³C NMR, IR, and elemental analyses of synthesized compounds. The title compounds were derived from 4-(4-nitrophenoxy)phenyl thiourea, which is the key intermediate in the synthesis of nitroscanate, an anthelmintic drug. Among the synthesized compounds, N-4-(4-nitrophenoxy)phenyl]-4-(4-fluorophenyl)-1,3-thiazol-2-amine and N-4-(4-nitrophenoxy)phenyl]-4-(4-methoxyphenyl)-1,3-thiazol-2-amine exhibited potent anthelmintic and antibacterial activities.
