The invention relates to 3α-ethynyl, 3β-hydroxy, 5α-pregnan-20-oxime or a pharmaceutically acceptable salt thereof, which compounds and/or salts are useful as modulators of the mammal brain excitability via the gamma-5 aminobutyric acid receptor-chloride ionophore (GABA.sub.A-R) complex and in the treatment of disorders such as hepatic encephalopathy, Down's syndrome and Alzheimer's disease.

Described herein are compositions and methods for hormone replacement therapy that address the shortcomings of the existing methods. Described herein are pharmaceutically effective partial agonistic antiprogestins. The combined application of estrogens (such as estradiol, estriol and conjugated estrogens) and the disclosed partial agonistic antiprogestins can be used in hormone replacement therapy.

The present invention refers to a process for the preparation of (3α,5α)-20-oxopregnan-3-yl glycyl-L-valinate hydrochloride, a compound having the formula I reported below:

This disclosure relates to progesterone phophate derivatives and uses related thereto. In certain embodiments, the disclosure relates to compounds disclosed herein and uses for managing inflammation such as those resulting from traumatic brain injury or stroke.

Thionyl tetrafluoride gas reacts efficiently with primary amines to form reactive iminosulfur oxydifluoride compounds. These dual S.sup.VI—F loaded iminosulfur oxydifluoride compounds, in turn, readily react with secondary amines or aryloxy silyl ethers (ArO—SiR.sub.3), yielding the corresponding fused heteroatom-linked substrates. Iminosulfur oxyfluoride polymers also are provided by disclosed methods.

Described herein are steroids of Formula (I): and pharmaceutically acceptable salts thereof; wherein R.sup.1, R.sup.2a, R.sup.2b, R.sup.3, R.sub.4, R.sup.5a, R.sup.5b, R.sup.6, and Z are as defined herein. Such compounds are contemplated useful for the prevention and treatment of a variety of CNS-related conditions, for example, treatment of sleep disorders, mood disorders, schizophrenia spectrum disorders, convulsive disorders, disorders of memory and/or cognition, movement disorders, personality disorders, autism spectrum disorders, pain, traumatic brain injury, vascular diseases, substance abuse disorders and/or withdrawal syndromes, and tinnitus.

Chemical compounds and the therapeutic use thereof, in particular for improving muscular quality in mammals. More particularly, a method of improving muscular quality in sarcopenic mammals and treating and/or preventing sarcopenia using the chemical compounds and, in particular, sarcopenic obesity and the associated complications and/or pathologies thereof, such as loss of strength, muscle mass, performance and of physical and movement capacity. Also, a method of improving muscle quality in obese mammals and treating and/or preventing of obesity and associated complications and/or pathologies, advantageously type 2 diabetes and metabolic syndrome, using the chemical compounds.

The invention provides novel manganese catalysts such as [Mn(.sup.tBuPc)], which are general for the amination of all types of C(sp.sup.3)-H bonds (aliphatic, allylic, propargylic, benzylic, ethereal), including strong 1.sup.o aliphatic C—H bonds, while achieving excellent chemoselectivity, stereospecificity, and high functional group tolerance. We demonstrate the late-stage diversification of bioactive complex molecules that encompass the range of C(sp.sup.3)-H bond types, such as selective 1.sup.o C—H aminations of betulinic acid and pleuromutilin derivatives. The catalysts' unprecedented balance of reactivity and selectivity is in part attributed to its mechanism of C—H amination that lies between stepwise and concerted.

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.
