  • Desoxycyclodepsipeptides and their use for combatting endoparasites
    Patent number: 6355615
    Abstract: The invention relates to novel deoxycyclodepsipeptides which are prepared from cyclodepsipeptides having 24 ring members which are constructed from alternating &agr;-aminocarboxylic acids and &agr;-hydroxycarboxylic acids, by complete or partial chemoselective reduction of the carbonyl groups of the amide function to give methylene groups using suitable reduction processes, and to mixtures and derivatives thereof. The deoxycyclodepsipeptides according to the invention have anthelmintic activity.
