In Silico Toxicological, Anti-Tubercular Effect Evaluation And In Vitro Marine Pathogenic Bacteria Inhibition of N-[(3-Chloro-4-Nitro-Phenyl)Methyleneamino]Pyridine-4-Carboxamidine
Toxicological, Anti-Tubercular Effect Evaluation
The hydrazone; N-[(3-chloro-4-nitro-phenyl) methyleneamino] pyridine-4-carboxamidine (H) was selected for in silico toxicological and in vitro bactericidal studies. Toxicological investigation was carried out using software program, such as eMolTox and Gusar, for the toxic substructure determination, and acute rat toxicity prediction respectively. In vitro bactericidal effect evaluation was investigated using tow marine pathogenic bacteria; Vibrio anguillarum and Photobacterium damselae. Computational results determinate toxicophores of (H), which are nitro-aromatic part, hydrazine group, and quaternary carbon, were predicted as responsible for Idiosyncratic toxicity metabolic activation, covalent bond with DNA, and hepatotoxicity respectively. In addition, the predicted LD50 of (H) are 1086, 244, 1816, and 823.40 mg/kg in intraperitenial, intravenous, oral and subcutaneous administration respectively. For bactericidal results, H exhibited an excellent effect with inhibition percentages of 98.65 and 98.83% at the concentrations of 1000 and 500 µg/mL against Vibrio anguillarum respectively, the same effect was demonstrated against Photobacterium damselae with inhibition percentages of 97.74 and 97.98 % at the same concentrations. For anti-tubercular effect prediction, results revealed that H has an excellent effect with probability percentage of 84.6%.
