concise and efficientapproach to polyenic compounds containing important diketone structural fragments is developed from readily available α,β-unsaturated methyl ketones in the presence of copper(II) oxide, iodine, and dimethyl sulfoxide. This is a new carbon–carbon double bond-forming reaction from two methyl sp3 C–H bonds and an attractive route to introduce the SMe group into the molecule from inexpensive
The present disclosure relates to novel cocrystals and novel methods for cocrystallization. In particular, the disclosure includes cocrystals comprising a salt of an active agent, such as a chloride salt of an active pharmaceutical ingredient. The present disclosure also relates to methods of preparing cocrystals and methods for screening for solid state phases.

The present invention has an object to provide an external dermal composition for anti-ageing, which prevents or improves apparent skin problems such as wrinkles, fine wrinkles, blemishes, and saggings caused by increasing age or ageing; and maintains or improves the barrier function and the hyaluronic acid production in the skin. The object is solved by providing an external dermal composition for anti-ageing, which contains an aqueous medium as a base material and one or more ingredients selected from L-ascorbic acid, derivatives thereof, and their salts as an effective ingredient(s).
It is intended to provide a novel deodorant composition which is excellent in the deodorizing effect, is capable of affording a deodorant composition by a convenient method, and shows no decrease in the deodorizing performance even after a long period of time, once the deodorant being prepared. Specifically, there is provided a deodorant composition containing, as the active component, a colored compound obtainable by reacting a polyphenol in a solvent showing alkalinity in the coexistence of an oxygen molecule at a reaction pH value of 6.5 or more. As a substitute for a polyphenol, use can be made of a plant extract containing a polyphenol but containing substantially no amino acid. It is also possible to further employ an amino acid. Furthermore, use can be made of a plant extract and/or a plant body containing a polyphenol and an amino acid.
