Effect of Conformational Preorganization of a Three-Armed Host on Anion Binding and Selectivity
摘要:
A set of three-armed urea-containing anion receptors was prepared. The receptors all have the same binding topology but differ in the level of conformational preorganisation with respect to the arrangement of the side-arms relative to the platform and within the side arms themselves. This is mirrored in a specific increase (x 2.5) in the binding constant for chloride and in a 12-fold increase in the chloride nitrate-selectivity.

The present invention relates to a method for reducing the production of methane emanating from the digestive activities of a ruminant by using as active compound at least one azido alkanoic acid and/or derivative thereof, which is administrated to the animal together with the feed. The invention also relates to the use of these ingredients in feed and feed additives such as premix, concentrates and total mixedration (TMR) or in the form of a bolus.
