Abstract:

Background: literature survey has pointed out that Benzimidazoles represent an interesting class of anthelmintics of which several potent members were developed.

Objective: Benzimidazoles hybridized with pharmacophoric moieties possessing anthelmintic activity were designed, synthesized to be evaluated against cercaria.

Methods: Structural modification was achieved through 2- and 5-positions. Moreover, in vitro cercarial assay was adopted to evaluate target compounds.

Results: Biological screening revealed that compound 3h showed significant activity with survival index of 35% at a 100 µg/mL concentration. Whereas, compounds 3a and 3c showed moderate activity, the rest of tested compounds exhibited low activity.

Conclusion: The current study evidenced that the new hybrids "benzimidazole-thiophen-aryl" are successful as cercacidal agents. Further studies of this novel tri-ring systems are suggested on adult worms of S. Mansoni.

Keywords: Shistosoma, Benzimidazoles, Cercarial Assay, thiophene, Suzuki-Miyaura, Anthelmintic.
