Abstract
Fungicides reduce the risk of mycopathologies and reduce the content of mycotoxins in commercial grain. The effect of fungicides on the structural and functional status of the root system of grain crops has not been studied enough. In this regard, we studied the phytocytotoxic effects tebuconazole (TEB) and epoxiconazole (EPO) and azoxystrobin (AZO) in the roots of Triticum aestivum seedlings in hydroponic culture. In the presence of EPO and AZO (but not TEB) inhibition of the root growth was accompanied by a dose-dependent increase in the content of malondialdehyde, carbonylated proteins, and proline in roots. TEB was characterized by a dose-dependent decrease in the total amount of border cells (BCs) and the protein content in root extracellular trap (RET). For EPO and AZO, the dose curves of changes in the total number of BCs were bell-shaped. AZO did not affect the protein content in RET. The protein content in RET significantly decreased by 3 times for an EPO concentration of 1 µg/mL. The obtained results reveal that the BC-RET system is one of the functional targets of fungicides in the root system of wheat seedlings. Studied fungicides induce oxidative stress and structural and functional alterations in the BC-RET system that can affect their toxicity to the root system of crops.

Abstract
As a typical and broad-spectrum benzimidazole, mebendazole (MBZ) has long been used in human and veterinary medicine to treat parasitic infestations, and is widely employed in the aquaculture of Japanese pufferfish (Takifugu rubripes). However, there have been no studies examining the pharmacokinetic characteristics of MBZ in Japanese pufferfish. Furthermore, the presence of MBZ and its metabolites in animal-derived raw food represents a notable safety concern. Here, we investigated the metabolism of MBZ using a UPLC-Q-TOF system. Additionally, we evaluated the pharmacokinetics of MBZ and two metabolites, 2-amino-5(6)-benzoylbenzimidazole (MBZ-NH2) and 5-hydroxymebendazole (MBZ-OH), in Japanese pufferfish following intramuscular injection of 20 mg/kg MBZ. We detected three metabolites of MBZ (M1-M3), among which, 2-amino-5(6)-(a-hydroxybenzyl) benzimidazole (M3) was detected in an aquatic animal for the first time. The plasma dispositions of MBZ, MBZ-NH2, and MBZ-OH were characterized by low plasma clearance, medium distribution volume, and long terminal half-life. Moreover, these compounds were widely distributed in the muscle, from which they were rapidly cleared. The pharmacokinetics and metabolism of mebendazole in Japanese pufferfish are described for the first time in this study. Our findings provide a basis for the rational application of MBZ in Japanese pufferfish farming and contribute to our understanding of the metabolism of MBZ in cultured fish.

Abstract
Agmatine N-acetyltransferase (AgmNAT) catalyzes the formation of N-acetylagmatine from acetyl-CoA and agmatine. Herein, we provide evidence that Drosophila melanogaster AgmNAT (CG15766) catalyzes the formation of N-acetylagmatine using an ordered sequential mechanism; acetyl-CoA binds prior to agmatine to generate an AgmNAT•acetyl-CoA•agmatine ternary complex prior to catalysis. Additionally, we solved a crystal structure for the apo form of AgmNAT with an atomic resolution of 2.3 Å, which points towards specific amino acids that may function in catalysis or active site formation. Using the crystal structure, primary sequence alignment, pH-activity profiles, and site-directed mutagenesis, we evaluated a series of active site amino acids in order to assign their functional roles in AgmNAT. More specifically, pH-activity profiles identified at least one catalytically important, ionizable group with an apparent pKa of ~7.5, which corresponds to the general base in catalysis, Glu-34. Moreover, these data led to a proposed chemical mechanism, which is consistent with the structure and our biochemical analysis of AgmNAT.
