This invention relates the use of cortisol blockers (e.g., glucocorticoid receptor [GR] antagonists) for the treating or preventing viral infections, treating or preventing treatment resistant prostate cancer, treating or preventing neoplasia, and treating or preventing infection related to acute or chronic injury or disease.

The present invention provides compounds of Formula I: ##STR00001##
pharmaceutical compositions comprising these compounds and methods of using these compounds to treat or prevent a disease or disorder mediated by FXR and/or TGR5.

This invention relates to methods of stimulating the activity of the human and animal enteric nervous system. The method comprises orally administering an aminoserol, such as squalamine, a naturally occurring aminosterol isolated from Squalus acanthias, or derivatives thereof, to a subject in need.

Disclosed herein are novel compounds, pharmaceutical compositions comprising such compounds and related methods of their use. The compounds described herein are useful, e.g., as liposomal delivery vehicles to facilitate the delivery of encapsulated polynucleotides to target cells and subsequent iransfection of said target cells, and in certain embodiments are characterized as having one or more properties that afford such compounds advantages relative to other similarly classified lipids.

The present invention provides a compound of formula (I):

##STR00001##

or a pharmaceutically acceptable salt, solvate, or amino acid conjugate thereof, wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, and R.sup.6 are as described herein. The present invention relates generally to selective FXR agonists and to methods of making and using them.

This disclosure provides crystalline polymorphs of squalamine phosphate, methods of making the same, and methods of treatment using the same.

The invention provides for treating HBV or HDV infection or inhibiting human sodium taurocholate co-transporting polypeptide (hNTCP) with a polymeric bile acid or salt thereof, and pharmaceutical compositions comprising a polymeric bile acid or salt thereof, and a second HBV or HDV medicament.

Disclosed are cationic lipids which are compounds of Formula I. Cationic lipids provided herein can be useful for delivery and expression of mRNA and encoded protein, e.g., as a component of liposomal delivery vehicle, and accordingly can be useful for treating various diseases, disorders and conditions, such as those associated with deficiency of one or more proteins. ##STR00001##

The invention concerns lipid assemblies, liposomes having an outer surface comprising a mixture of anionic and cationic moieties; wherein at least a portion of the cationic moieties are imino moieties that are essentially charged under physiological conditions, and their use for serum resistant transfection of cells.
