Plants which have been sprayed with N-alkylalkanolamines and/or N-alkylalkanolammonium salts have been found to show much less tendency of suffering plant virus diseases when applied as they are or after being dissolved in solvent. The N-alkylalkanolamine is prepared by reacting an alkanolamine with an alkyl halide in the presence of a basic substance.

7169818 - Lysophosphatidic acid receptor agonists and antagonists - Owned by University of Virginia Patent Foundation (Charlottesville, VA) The present invention is directed to compositions comprising lysophosphatidic acid analogs and methods of using such analogs as agonist or antagonists of LPA receptor activity. In addition the invention is directed to LPA receptor agonists that vary in the degree of selectivity at individual LPA receptors (i.e. LPA1, LPA2 and LPA3). More particularly the present invention is directed to LPA analogs wherein the glycerol is replaced with ethanolamine and a variety of substitutions have been linked at the second carbon atom.
