Hexaconazole exposure disrupt acetylcholinesterase, leading to mental illness.

Abstract

Hexaconazole is widely used in agricultural work, and it has been observed that it has potential to disrupt endocrine function and it has also capacity of bioaccumulation. In this study, we examined how the hexaconazole disrupts the usual balance of acetylcholinesterase. It has been already reported that heavy pesticide exposures may be a reason for several mental illnesses because these pesticides may disrupt normal balance of acetylcholinesterase. In this paper, we have done a complete molecular and dynamics analysis to understand the behavior of hexaconazole with acetylcholinesterase so that its toxicological aspect may be explored. Our findings revealed that hexaconazole has potency to interact with acetylcholinesterase in a stable manner. The binding energy of hexaconazole was found to be -7.95 kcal/mol. However, chlorpyrifos, known inhibitors of acetylcholinesterase, has binding energy of -7.17 kcal/mol. With respect to stability analysis, hexaconazole has similar stability like chlorpyrifos. Root-mean-square deviation, root-mean-square fluctuation, radius of gyration, hydrogen bonding, and solvent accessible surface area were similar to chlorpyrifos. In addition, density functional theory computations analysis reveals that hexaconazole is energetically stable like chlorpyrifos, which is necessary for establishing a stable ligand-protein complex. The result of this complete molecular analysis reveals that hexaconazole may disrupt the acetylcholinesterase balance, which leads to mental illness.
