This disclosure provides improved lipid-based compositions, including lipid nanoparticle compositions, and methods of use thereof for delivering agents in vivo including nucleic acids and proteins. These compositions are not subject to accelerated blood clearance and they have an improved toxicity profile in vivo.
Compounds of the general formula ##STR1## wherein two of the residues R.sup.1, R.sup.2 and R.sup.3 represent C.sub.10-30 -alkyl residues with at least 8 C-atoms in a straight chain, at least one of these residues being substituted by at least 2 C.sub.1-3 -alkyl residues and the sum of the C-atoms in the two residues being greater than 20; and the third residue is a residue --P(O)(O.sup.-)OR.sup.4 in which R.sup.4 represents a lower-alkyl or C.sub.5-7 -cycloalkyl residue which is substituted by a quaternary ammonium group or a C.sub.5-7 -cycloalkyl residue which contains a di-(lower-alkyl)-substituted nitrogen atom, are useful for the manufacture of colloidal solution systems. The compounds of formula I can be prepared starting from glycerol derivatives as described in more detail in the specification.

Glycerinäther-phosphatide der Formel
worin zwei der Reste R1, R2 und R3 C10-30-Alkylreste mit mindestens 8 C-Atomen in gerader Kette darstellen, wobei mindestens einer dieser Reste durch mindestens 2 C1-3-Alkylreste substituiert ist und die Summe der C-Atome in beiden Resten grösser als 20 ist; und der dritte Rest ein Rest - P(O)(O-)OR4 ist, worin R4 einen durch eine quaternäre Ammoniumgruppe substituierten nieder-Alkyl- oder C5-7-Cycloalkylrest oder einen ein di-(nieder-Alkyl)-substituiertes Stickstoffatom enthaltenden C5-7-Cycloalkylrest darstelit, verwendbar bei der Herstellung kolloidaler Lösungsmittelsysteme, werden ausgehend von den Verbindungen der Formel 1 analogen Verbindungen, worin Wasserstoff an Stelle einer der Reste R1, R2 und R3 vorliegt, hergestellt.
