Aminothiophenedicarboxamides and dicyanothiopheneacetamides as effective synthetic molluscicides against Indoplanorbis exustus snail.

New thiophenedicarboxamide 2a-c and dicyanothiopheneacetamide 3a-c derivatives were synthesized and their bioactivity against Indoplanorbis exustus snails was evaluated. The I. exustus snail is a serious host of parasite of genus Schistosoma which infects cattle.
