Described herein are liposomes containing etherlipids of the formula:as well as a phosphatidylcholine, a sterol, and a headgroup-derivatized lipid. These liposomes are useful in a variety of therapeutic regimens, including the treatment of cancers and inflammatory disorders.

Etherlipid-containing multiple lipid liposomes

This invention provides a taxane derivative of the formula:

Hydrophobic taxane derivatives

Described herein are liposomes containing etherlipids of the formula:

This invention provides a taxane derivative of the formula: ##STR1## wherein a hydrophobic organic moiety is attached to a taxane. R and R.sup.1 is each indepently H or a hydrophobic organic moiety, as long as at least one of R and R.sup.1 is not H. Attachment of a hydrophobic organic moiety to the taxane so as to obtain a taxane derivative generally stabilizes the association of the derivative with a lipid, including a liposomal lipid, carrier in the plasma of animals to which the derivative-carrier association is administered. Also provided herein is a composition containing the taxane derivative and a pharmaceutically acceptable medium; desirably, the medium also contains a lipid carrier, and the derivative is associated with the carrier. Further provided herein is a method of administering taxane derivatives to animals, for example, animals afflicted with cancers.

Preparation of liposomal taxanes

Described herein are methods of preparing liposome-containing pharmaceutical compositions, the liposomes containing headgroup-derivatized lipids and etherlipids having the formula: ##STR1## Such compositions are useful in the treatment of a variety of conditions, including various cancers and inflammatory disorders.

Preparation of pharmaceutical compositions containing

Described herein are liposomes containing etherlipids of the formula: ##STR1## as well as a phosphatidylcholine, a sterol, and a headgroup-derivatized lipid. These liposomes are useful in a variety of therapeutic regimens, including the treatment of cancers and inflammatory disorders.

Liposomes are provided which contain etherlipids having the formula: ##STR1## as well as an unsaturated or partially unsaturated phospholipid, a sterol, and a phosphatidylethanolamine-based headgroup-derivatized lipid. These liposomes are useful in a variety of therapeutic regimens, including the treatment of cancers and inflammatory disorders.

Etherlipid containing multiple lipid liposomes

Synthesis of hydrophobic taxane derivatives

Liposomes are provided which contain ether lipids having the formula: ##STR1## as well as an underivatized phosphatidylethanolamine, a sterol, and a phosphatidylethanolamine-dicarboxylic acid headgroup-derivatized lipid. These liposomes are useful in a variety of therapeutic regimens, including the treatment of cancers and inflammatory disorders.

Multilipid component ether lipid liposomes

Provided herein is a method of administering a liposome composition to an animal, the method involving adminstering to the animal a liposome composition containing an adverse physiological reaction-reducing effective amount of a liposome which has, in addition to a bioactive agent, a lipid bilayer containing a lipid and a surface agent-modified molecule. An adverse physiological reaction which may be experienced by the animal upon administration of a liposome composition is reduced by way of the presence of the surface agent-modified molecule in the liposome's lipid bilayer.
