P126 BIOTRANSFORMATION OF ALBENDAZOLE IN PLANTAGO LANCEOLATA Stuchlíková Lucie1, Podlipná Radka2, Szotáková Barbora1, Skálová Lenka1 Department of Biochemical Sciences, Faculty of Pharmacy in Hradec Králové, Charles University in Prague, Heyrovského 1203, 500 05 Hradec Králové, Czech Republic1, Laboratory of Plant Biotechnologies, Institute of Experimental Botany, Czech Academy of Science, Rozvojová 263, 165 02, Praha 6, Czech Republic2 E-mail: [email protected] Sekce: Proteomika a metabolomika Albendazole (ABZ) with other benzimidazole drugs are anthelmintics widely used in veterinary medicine in order to treat diseases in agriculture and also in human medicine (Danaher et al., 2006). The usefulness of these drugs is uncontested, but at the same time they represent a risk to the environment. ABZ administered to animals enter into environment primarily through its excretion in faeces or urine. Following excretion, ABZ may persist in the environment and impact non-target organisms. Phytoremediation is a highly promising method that uses various plants and their associated microbes to degrade, accumulate, or immobilize contaminants from soil and water. Plants are able to uptake xenobiotics, including drugs, and detoxify them via biotransformation. However, only drug biotransformation into non-toxic and stable metabolites and their consequent accumulation in plants represent drug detoxification. For that reasons, knowledge of biotransformation pathways of drug in plants is very important. The objectives of this study were to identify the ABZ metabolites and ABZ biotransformation pathways in meadow plants - cell suspensions (Plantaga lanceolata), which commonly growth on pastures. Callus culture was achieved from primary callus rising on stem segments of plant seedlings. Suspension cultures derived from this callus were grown. The suspensions were incubated with ABZ (10 µM) for 24 hours. Before analysis, homogenized samples were subjected to liquid–liquid extraction. The samples were analysed using UHPLC/MS (QqQ) in positive-ion mode. The results showed that ABZ entered plant cells and enzymatic systems of plant were able to transform ABZ via several reactions.
