Commercially available pesticides were examined as and acetylcholinesterase (AChE and AChE) inhibitors by means of ligand-based (LB) and structure-based (SB) in silico approaches. Initially, the crystal structures of simazine, monocrotophos, dimethoate, and acetamiprid were reproduced using various force fields. Subsequently, LB alignment rules were assessed and applied to determine the inter synaptic conformations of atrazine, propazine, carbofuran, carbaryl, tebufenozide, imidacloprid, diuron, monuron, and linuron.

Compounds 2a, 2b, and 2f without genotoxic activity were applied prior to ethyl methanesulfonate (EMS) and diminished EMS-induced DNA damage according to the total score and percentage of reduction. EMS produce harmful O(6)-ethylguanine lesion which is incorporated in aberrant genotoxic GT and TG pairing after ATP-dependent DNA strand breaks have been catalyzed by rat Topoisomerase IIα (rTopIIα, EC 5.

Derivatives were selected from a group of six previously intraperitoneally applied compounds on the basis of presenting remarkable activity in a concentration of 2 mg/kg of body weight. The derivatives 2a and 2f are VKORC1 inhibitors, and comparison of the absorption spectra, association, and dissociation constants suggested that the compounds will be bound to serum albumin in the same manner as warfarin is, leading to transfer towards the molecular target VKORC1.

Pretreatment with GCA and GCR, containing sweroside, swertiamarin and gentiopicrin in high concentrations, dose-dependently and significantly decreased the levels of serum transaminases, alkaline phosphatase and total bilirubin, whereas an increase in the level of total protein was found compared with the CCl4-treated group.

Two of them, 2f and 2a, in concentration of 2mg/kg of body weight, presented remarkable activity (PT=130s; PT=90s) upon seven days of continuous application. The results of rat serum and liver biochemical screening, as well those of histopathological studies, proved the compounds to be non-toxic.
