The first total synthesis of monensin was reported in 1979 by Kishi et al.[3] Mechanism of actionMonensin A is an ionophore related to the crown ethers with a preference to form complexes with monovalent cations such as: Li+, Na+, K+, Rb+, Ag+, and Ti+.[4][5] Monensin A is able to transport these cations across lipid membranes of cells in an electroneutral (i.e. non-depolarizing) exchange, playing an important role as an Na+/H+ antiporter. Recent studies have shown that monensin may transport sodium ion through the membrane in both electrogenic and electroneutral manner.[6] This approach explains ionophoric ability and in consequence antibacterial properties of not only parental monensin, but also its derivatives that do not possess carboxylic groups. It blocks intracellular protein transport, and exhibits antibiotic, antimalarial, and other biological activities.[7] The antibacterial properties of monensin and its derivatives are a result of their ability to transport metal cations through cellular and subcellular membranes.[8] UsesMonensin is used extensively in the beef and dairy industries to prevent coccidiosis, increase the production of propionic acid and prevent bloat.[9] Furthermore, monensin, but also its derivatives monensin methyl ester (MME), and particularly monensin decyl ester (MDE) are widely used in ion-selective electrodes.[10][11][12] In laboratory research, monensin is used extensively to block Golgi transport.[13][14][15] ToxicityMonensin has some degree of activity on mammalian cells and thus toxicity is common. This is especially pronounced in horses, where monensin has a median lethal dose 1/100th that of ruminants. Accidental poisoning of equines with monensin is a well-documented occurrence which has resulted in deaths.[16] References1. ^1 {{cite journal |author= Daniel Łowicki and Adam Huczyński|year= 2013|title= Structure and Antimicrobial Properties of Monensin A and Its Derivatives: Summary of the Achievements|journal= BioMed Research International|volume= 2013|issue= |pages=1–14|doi=10.1155/2013/742149}} {{Nonribosomally synthesized porters}}2. ^Patrick Butaye, Luc A.
