  • Publication number: 20100044617
    Abstract: A process for preparing a high-purity quaternary ammonium salt comprising: (1) adding an oxide or hydroxide of a Group 1, 2, 12 or 13 metal to a quaternary ammonium salt containing a protonic acid salt of a tertiary amine as an impurity and thereby neutralizing the tertiary amine protonic acid salt with the metal oxide or hydroxide to convert the acid salt to a tertiary amine and water and to convert the metal oxide or hydroxide to a metal salt at the same time, and (2) removing the tertiary amine, water and metal salt produced from the system.

  • Patent number: 7598421
    Abstract: The invention provides a lipid of general formula (I) or (II): wherein X1, X2 and R1 to R5 are as defined herein. Such lipids are used to form complexes with a biologically-active material such as a nucleic acid, peptide or small molecule for delivering the biologically-active material to cells. The complexes may incorporate an integrin-binding peptide and, when the biologically-active material is DNA, thereby constitute a LID complex.
