Disclosed are compounds that accumulate in Gram-negative bacteria. Also disclosed are method of antimicrobial treatment using the compounds.

The present invention discloses a process for the preparation of 16, 17-acetals of pregnane derivatives having formula I ##STR00001##
wherein each substituent is independently selected from; R.sub.1 is H or CH.sub.3; R.sub.2 is C.sub.1-C.sub.6 linear or branched alkyl, alkynyl group or cycloalkyl group; aryl or heteroaryl group; or R.sub.1 and R.sub.2 combine to form saturated, unsaturated C.sub.3-C.sub.6 cyclic or heterocyclic ring; R.sub.3 and R.sub.4 are same or different and each independently represents H or halogen; R.sub.5 is OH or OCOR wherein R represents H or C.sub.1-C.sub.6 linear, branched or cyclic alkyl group that may be substituted.

The present invention discloses method for preparing deoxycholic acid (DCA) or an ester thereof or a pharmaceutically acceptable salt thereof. Said compounds may be applied to remove a fat deposition.

The invention relates to an antagonist of CB1 receptor for use in the treatment of a pathologic condition or disorder selected from the group consisting of bladder and gastrointestinal disorders; inflammatory diseases; cardiovascular diseases; nephropathies; glaucoma; spasticity; cancer; osteoporosis; metabolic disorders; obesity; addiction, dependence, abuse and relapse related disorders; psychiatric and neurological disorders; neurodegenerative disorders; autoimmune hepatitis and encephalitis; pain; reproductive disorders and skin inflammatory and fibrotic diseases.

Synthetic methods for preparing deoxycholic acid and intermediates thereof are provided.

Synthetic methods for preparing deoxycholic acid and intermediates thereof are provided.

The present application relates to a method of preparing compounds of Formula (I) or a pharmaceutically acceptable salt, solvate, or amino acid conjugate thereof, R.sub.1 is H, -OH, -OH, or an oxo group.

##STR00001##

The present invention discloses method for preparing deoxycholic acid (DCA) or an ester thereof or a pharmaceutically acceptable salt thereof. Said compounds may be applied to remove a fat deposition.

The present disclosure is generally directed to neuroactive 13, 17-substituted steroids as referenced herein, and pharmaceutically acceptable salts thereof, for use as, for example, an anesthetic, and/or in the treatment of disorders relating to GABA function and activity. The present disclosure is further directed to pharmaceutical compositions comprising such compounds.

The present disclosure provides modified neuroactive steroids. The modified neuroactive steroids may comprise, consist of or consist essentially of a therapeutic agent and/or a modifying moiety. The modified neuroactive steroid can have modified characteristics as compared to native neuroactive steroids that do not include a modifying moiety and/or therapeutic agent. The modified neuroactive steroid may be, for example, modified pregnenolone, pregnenolone metabolites, allopregnanolone, and/or allopregnanolone metabolites. The modified neuroactive steroids can be used to treat, prevent and/or ameliorating a phenotypic state of interest in a subject.
