    Emodepside

    $278.25 - $535.50

    Emodepside is an anthelmintic, belonging to the cyclooctadepsipeptides class. It is effective against gastrointestinal nematodes. The starting material of Emodepside is a natural metabolite of the fungus Mycelia sterilia, which inhabits the leaves of Camellia japo

    Mechanism of Action

    Emodepside binds to G-protein coupled receptors called latrophilins. Following binding, the Gq protein activates the signaling molecule phospholipase C-β a protein that modulates regulatory pathways of vesicle release. The process involves Slo-1 (potassium channel). An unidentified transmitter interferes with signaling at the neuromuscular junction and affects nematode movement, feeding, and reproduction.

    Researchers at Bayer in Berlin, Germany found that Emodepside directly opens a Slo-1 channel. Slo-1 deficiant C. elegans are completely resistant to Emodepside. Molecular analyses identified full length Slo-1 cDNAs of a variety of species of parasitic nemotodes, and found substantial differences among channel properties (Kulke et al, 2014).
