Abstract

Drugs are potentially dangerous environmental contaminants, as they are designed to have biological effects at low concentrations. Monepantel (MOP), an amino-acetonitrile derivative, is frequently used veterinary anthelmintics, but information about MOP environmental circulation and impact is almost non-existent. We studied the phytotoxicity, uptake and biotransformation of MOP in two fodder plants, Plantago lanceolata and Medicago sativa. The seeds and whole plant regenerants were cultivated with MOP. The plant roots and the leaves were collected after 1, 2, 3, 4, 5 and 6 weeks of cultivation. The lengths of roots and proline concentrations in the roots and leaves were measured to evaluate MOP phytotoxicity. The UHPLC-MS/MS technique with a Q-TOF mass analyser was used for the identification and semi-quantification of MOP and its metabolites. Our results showed no phytotoxicity of MOP. However, both plants were able to uptake, transport and metabolize MOP. Comparing both plants, the uptake of MOP was much more extensive in Medicago sativa (almost 10-times) than in Plantago lanceolate. Moreover, 9 various metabolites of MOP were detected in Medicago sativa, while only 7 MOP metabolites were found in Plantago lanceolata. Based o...Continue Reading

Anthelmintics (ASM)

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
