Monensin[2], koji je izolovan iz Streptomyces cinnamonensis[3], poznati je predstavnik prirodnih polietarskih[4][5] antibiotika.[6][7]
Hemijska struktura monensina je prvo opisana 1967. godine (Agtarp et al.). To je bio prvi polietarski antibiotik. Prvi izveštaj o totalnoj sintezi monensina je objavljen 1979. godine.[8]
Monensin A manifestuje naklonost ka formiranju kompleksa sa monovalentnim katjonima kao što su Li+, Na+, K+, Rb+, Ag+ and Tl+ [9][10][11][12]. Monensin A ima sposobnot transportovanja tih katjona kroz lipidne membrane ćelija, što mu daje značajnu ulogu Na+/H+ antitransportera. On blokira intraćelijski proteinski transport, i poseduje antibiotička, antimalarijska, i druga biološka svojstva.[13]. Antibakteriske osobine Monensina i njegovih derivata su rezultat njihove sposobnosti da transportuju metalne katjone kroz ćeliske i intraćeliske membrane.[14][15][16].

Monenin je u širokoj upotrebi u industriji prerade mleka i mesa kao stredstvo za sprečavanje cocodiosisa, intenzivnog oslobađanja propionske kiselene.[17]. Monensin, monensin metil estar (MME), i posebno monensin decil estar (MDE) se široko koriste kao sastojak selectivnih elektroda.[18][19][20].
