Abstract: Disclosed are phytoecdysones and semisynthetic derivatives of phytoecdysones, intended to be used in treating impairment of the respiratory function in mammals, in particular in the context of a viral infection and more particularly during an infection by a coronavirus.

Abstract: The invention concerns a method for preparing an extract from a preparation of approximately 90% pure 20-hydroxyecdysone that comprises the following steps: g) Hot dissolution of approximately 90% pure 20-hydroxyecdysone in methanol, filtration and partial concentration, h) Addition of 1 to 5 volumes of acetone, i) Cooling to a temperature of between 0 and 5° C. while stirring, j) Filtration of the obtained precipitate, k) Successive rinses with acetone and water, and l) Drying.

Abstract: 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.

Abstract: The invention relates to the use of norbixin and an urucum extract enriched in bixin and/or norbixin as a food. The invention also provides a food preparation comprising norbixin, bixin or an extract comprising at least bixin or norbixin, the preparation being intended to be administered orally, for the protection of mammalian skin against UV-radiation.

Abstract: Phytoecdysones for use in improving muscle quality in obese and/or sarcopenic mammals, preferably, obese mammals subjected to a low-calorie diet. The phytoecdysones are advantageously incorporated into a food composition. The phytoecdysones can be derived from plants, such as quinoa.

Abstract: Phytoecdysones to avoid weight gain in obese mammals previously having undergone a hypocaloric weight-loss diet. The phytoecdysones are added to a food composition. The phytoecdysones can be from plants, such as quinoa.
