The invention relates to a synthesis of cholesterol; a ring opening step of the compound of formula (I) and subsequent activation and reduction step yielding cholesterol. The inventions relates also to intermediates achieved during said synthesis.

The invention relates to 17-hydroxy-17-pentafluoroethyl-estra-4,9(10)-dien-11-aryl derivatives of Formula I with progesterone antagonizing action and method of production thereof, use thereof for the treatment and/or prophylaxis of diseases and use thereof for the production of medicinal products for the treatment and/or prophylaxis of diseases, in particular of fibroids of the uterus (myomas, uterine leiomyoma), endometriosis, heavy menstrual bleeds, meningiomas, hormone-dependent breast cancers and complaints associated with the menopause or for fertility control and emergency contraception.

The sulfated oxysterol 5-cholesten-3, 25-diol 3-sulphate, a nuclear cholesterol metabolite that decreases lipid biosynthesis and increases cholesterol secretion and degradation, is provided as an agent to lower intracellular and serum cholesterol and/or triglycerides, and to prevent or treat lipid accumulation-associated inflammation and conditions associated with such inflammation. Methods which involve the use of this sulfated oxysterol to treat conditions associated with high cholesterol and/or high triglycerides and/or inflammation (e.g. hypercholesterolemia, hypertriglyceridemia, non-alcoholic fatty liver diseases, atherosclerosis, etc.) are also provided.

A process for preparing crystalline particles of an active principal in the presence of ultrasonic irradiation that comprises contacting a solution of a solute in a solvent in a first flowing stream with an anti-solvent in a second flowing stream causing the mixing thereof, wherein the flow rate ratio of the anti-solvent: solvent is higher than 20:1, and collecting crystals that are generated.

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.

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.

Boron-based prodrugs of phenol- or aromatic hydroxyl group-containing therapeutic molecules (original drugs), uses thereof, and methods of making the same, are provided for achieving, for example, improved bioavailability, prolonged retention (e.g., in a circulatory system) and, in particular, significantly lowered therapeutically effective dosage in order to reduce adverse effects while maintaining the desired therapeutic effects of the original drugs.

This invention describes compounds of Structures 1, 2, and 3 and their use as allosteric modulators of the GABA receptor chloride ionophore complex to alleviate stress, anxiety, mood disorders, seizures, depression, treatment of drug and alcohol abuse, memory, premenstrual disorders, and neural system damage. ##STR00001##
