Abstract:
Pure saponins and processes for making such saponins are described herein. In addition, cosmetic compositions, such as skin care compositions, comprising such saponins and methods for improving skin health and appearance with such skincare compositions are also described herein.
Abstract:
The invention relates to compounds of formula (I) and pharmaceutically acceptable salts thereof wherein R2to R7are as defined in the claims. The invention further relates to their use as inhibitors of 17β-HSD and in treatment or prevention of steroid hormone de- pendent diseases or disorders, such as steroid hormone dependent diseases or disorders requiring the inhibition of the 17β-HSD1 enzyme and/or requiring the lowering of the endogenous estradiol concentration. The present invention also relates to the preparation of the aforementioned compounds and to pharmaceutical compositions comprising as an active ingredient(s) one or more of the afore- mentioned compounds or pharmaceutically acceptable salts thereof.
Abstract:
The present invention relates to preparation and biological evaluation of 3-acetoxy-17- acetamido-16-formyl-androst-5,17-diene (4) and 3-acetoxy2'-chloro-5-androsteno [17,16- b]pyridine (5) as gastric proton pump inhibitor and their comparison to that of omeprazole, a clinically employed anti-gastric ulcer drug. Compound (4) exhibited dose dependent inhibition of histamine-stimulated acid secretion in gastric parietal cell with an IC 50 value comparable to cimetidine. No mortality or behavioral abnormality of Swiss albino mice was observed under single-dose level of 1g/Kg body weight of compound (4). Compound (4) further exhibited excellent anti ulcer activity in vivo against indomethacin induced ulcer.
Abstract:
The present invention relates to novel anti-inflammatory and antiallergic compounds of the glucocorticosteroid series, methods of preparing such compounds, pharmaceutical compositions comprising them, combinations and therapeutic uses thereof. More particularly, the invention relates to glucocorticosteroids that are derivatives of pyrrolidine.

Abstract:
The present invention provides methods for purifying at least one saponin in a solution comprising the steps of: (a) providing at least one saponin in a first solvent comprising a solubilizing component; (b) replacing at least a portion of the solubilizing component with an exchange solvent, thereby producing a replaced solvent; and (c) removing the replaced solvent, to produce a dried saponin product comprising at least one saponin.
Abstract:
The present invention relates to novel substituted steroid derivatives which represent selectiv inhibitors of the 17β-hydroxysteroid dehydrogenase type I (17β-HSD1) and, in addition, which may represent inhibitors of the steroid sulphatase, as well as to their salts, to pharmaceutical preparations containing these compounds and to processes for the preparation of these compounds. Furthermore, the invention concerns the therapeutic use of said novel substituted steroid derivatives, particularly their use in the treatment or prevention of steroid hormone dependent diseases or disorders, such as steroid hormone dependent diseases or disorders requiring the inhibition of 17β-hydroxysteroid dehydrogenase type I and/or steroid sulphatase enzymes and/or requiring the lowering of the endogenous 17β-estradiol concentration.
