Abstract

The aim of this work is to develop and improve anthelmintics that can contribute effectively to the control of certain new and resistant races of nematodes in the treatment of parasitic diseases in humans. This situation is of increasing concern to the agricultural, medical and health communities. The research carried out is particularly interested in the determination of the lipophilicity of a series of substituted molecules of the benzymidazolyl-chalcone family, molecules with proven activity against worms. This work has enabled us to predict and better understand their biological activities (antihistamines, antifungals, antiallergics, antibacterials and antivirals). It has also allowed us to identify the best anthelmintics that offer a broad spectrum of action, a high degree of efficacy, a good safety margin and a high degree of flexibility of use in order to limit resistance problems. The REKKER, KLOPMAN and IROFF methods and the MOLINSPIRATION software were used to determine the lipophilicity of these molecules. The values obtained for the partition coefficients revealed that these molecules are naturally lipophilic. These results allow us to appreciate the important role of molecular lipophilicity calculation methods in determining the mode of action of bioactive molecules.
