The present invention relates generally to compositions and methods for treating cancer and hypercortisolism. Provided herein are substituted steroidal derivative compounds and pharmaceutical compositions comprising said compounds. The subject compounds and compositions are useful for inhibition of glucocorticoid receptors. Furthermore, the subject compounds and compositions are useful for the treatment of cancer and hypercortisolism.

Described herein are methods and compositions related to inhibiting bile salt hydrolase (BSH) and uses thereof. Provided herein is a method for treating a metabolic disorder (e.g., diabetes, obesity), gastrointestinal disease (e.g., a gastrointestinal infection; inflammatory bowel disease (IBD); appendicitis; Crohn's disease (CD); ulcerative colitis (UC); gastritis; enteritis; esophagitis; pancreatitis; diabetes; hepatitis; liver diseases (e.g., Non-alcoholic Fatty Liver Disease (NAFLD); non-alcoholic steatohepatitis (NASH); hepatitis A; hepatitis B; hepatitis C; autoimmune hepatitis; and cirrhosis of the liver) gastroesophageal reflux disease (GERD); celiac disease; diverticulitis; food intolerance; ulcer; infectious colitis; irritable bowel syndrome; leaky gut; and cancer), cancer (e.g., cancer of the digestive system, liver cancer), or an inflammatory disease (e.g., Crohn's disease, inflammatory bowel disease, ulcerative colitis, pancreatitis, hepatitis, appendicitis, gastritis, diverticulitis, celiac disease, food intolerance, enteritis, ulcer, gastroesophageal reflux disease (GERD), psoriatic arthritis, psoriasis, and rheumatoid arthritis) in a subject in need thereof comprising administering to a subject a compound of Formulae (I)-(XVIII).

The present invention generally relates to new compounds for therapeutic uses. In particular, this disclosure relates to novel tetracyclic compounds useful for treatment of cancer, especially castration resistant prostate cancer. Pharmaceutical composition matters and methods for treating a cancer patient by administering therapeutically effective amounts of such compound alone or together with other therapeutics are within the scope of this disclosure.

The application relates to compounds of formula A: ##STR00001##
or a salt, solvate, ester, tautomer, amino acid conjugate, or metabolite thereof. The compounds of formula A are TGR5 modulators useful for the treatment of various diseases, including metabolic disease, inflammatory disease, autoimmune disease, cardiac disease, kidney disease, cancer, and gastrointestinal disease.

The invention relates to an efficient and industrially applicable process for the preparation and purification of allopregnanolone and intermediates thereof without the assistance of column chromatography.

A novel delivery system for drugs, and especially macromolecules such as proteins or oligonucleotides through biological membranes is provided, and specifically delivery of siRNA. The delivery system comprises conjugation of the macromolecule drug to a moiety that enables effective passage through the membranes. Respectively, novel compounds and pharmaceutical compositions are provided, utilizing said delivery system. In one aspect of the invention, the compounds may be utilized in medical practice, for example, in delivery of siRNA or antisense oligonucleotides across biological membranes for the treatment of medical disorders.

Provided herein is a compound of Formula (I):

##STR00001##

or a pharmaceutically acceptable salt thereof, wherein R.sup.1a, R.sup.1b, R.sup.2a, R.sup.2b, R.sup.3, R.sup.4a, R.sup.4b, R.sup.5, R.sup.6a, R.sup.6b, R.sup.7a, R.sup.7a, R.sup.11a, R.sup.11b, R.sup.12a, R.sup.12b, R.sup.16a, R.sup.16b, R.sup.19, R.sup.11a, R.sup.22, R.sup.X, R.sup.Y and n are defined herein. Also provided herein are pharmaceutical compositions comprising a compound of Formula (I) and methods of using the compounds, e.g., in the treatment of CNS-related disorders.

The present application discloses derivatives of hydroxysteroids, pharmaceutically acceptable salts, stereoisomers or tautomers thereof. The compounds and compositions described herein can be used in therapy.

The present invention provides compounds of Formula I, ##STR00001##
pharmaceutical compositions comprising these compounds and methods of using these compounds to prevent or treat FXR-mediated or TGR5-mediated diseases or conditions.

Steroid derivative regulators, a method for preparing the same, and uses thereof are described. Specifically, a compound as shown in formula (I), a preparation method therefor, a pharmaceutical composition containing the compound, and uses thereof as a regulator of GABA A receptor for treating depression, convulsion, Parkinson's disease, and nervous system diseases are described, wherein the substituents of the formula (I) are as defined in the description.
