Synthesis of certain benzothiazole derivatives to be evaluated as anthelmintics

New derivatives of 6-nitro-2-substituted acetamidobenzothiazole [2a, 3a-e], 3-substituted 2-iminothiazolidin-4-one [4a-e] and 5-arylidene-2-iminothiazolidin-4-one [5a-j] were prepared. The testing for the anthelminitic activity of two of the newly prepared compounds using the earthworm method showed that they produce a promising effect. The detailed synthesis, spectroscopic and biological data are reported

Synthesis and antihelminthic properties of new benzimidazoles

The synthesis of certain pyrazoline, 3-cyanopyridone, isoxazoline, pyrimidin-2-one, pyrimidine-2-thione, pyrrolo [1,2-a] benzimidazole-3-one and thieno [3,4-c] pyrazole derivatives of benzimidazole was described. The anthelmintic activity of three of the newly prepared compounds was evaluated using the earthworm method
