Abstract:
Изобретение относится к области создания имитаторов запаха наркотических средств и психотропных веществ, предназначенных для тренировки и обучения собак кинологической службы на обнаружение наркотических средств и психотропных веществ. Жидкий имитатор включает ароматическую добавку, имитирующую запах наркотических средств и психотропных веществ, фиксатор запаха - диметикон и/или циклометикон, солюбилизатор/эмульгатор - сорбитан моноолеат и/или сорбитан монопальмитат и растворитель -этиловый спирт или водно-спиртовый раствор 70%-ный при следующем соотношении исходных ингредиентов, масс. %: ароматическая добавка, имитирующая запах наркотических средств и психотропных веществ 1,0-10,0; диметикон и/или циклометикон 1,0-5,0; сорбитан моноолеат и/или сорбитан монопальмитат 1,0-8,0; этиловый спирт или водно-спиртовый раствор 70%-ный - остальное. Изобретение позволяет создать жидкую композицию имитатора запаха наркотических средств и психотропных веществ, которая обеспечивает возможность быстрого и легкого дозированного нанесения одорологической «метки» как непосредственно на различные предметы, одежду, стены или другие поверхности.
Abstract:
Provided herein is a process for preparing solid lipid nanoparticles of curcumin. Also provided herein are solid lipid nanoparticles of curcumin having a particle size in the range of 20-800 nm.The solid lipid nanoparticles of curcumin show a very high entrapment efficiency of curcumin in the range of 50-100% in terms of actual curcumin content of the formulation. The solid lipid nanoparticles of curcumin show increased efficacy of the curcumin.
Abstract:
Fluoroalkyl (meth)acrylate polymers or copolymers are described. These fluoroalkyl (meth)acrylate polymers or copolymers are prepared from at least 96% by weight of one or more fluoroalkyl (meth)acrylate monomers, wherein the fluoroalkyl group has 1 to 6 carbon atoms. The fluoroalkyl (meth)acrylate polymers or copolymers have high molecular weights and glass transition temperatures above room temperature.
Abstract:
The present invention describes new derivatives of S-allyicysteine with antioxidant and antiaging activity. Said derivatives can be used alone or in a combined formulation with other compounds with known activity.
Abstract:
This invention provides a novel method for the preparation of 2,3- disubstituted-4-oxy-cyclopentan-l-one compounds that are useful for the synthesis of prostaglandins and prostaglandin analogs of industrial relevance. The method comprises the metal -catalyzed asymmetric 1,4-conjugate addition of vinylboron compounds to 2- substituted-4-oxy-cyclopent-2-en-l-ones. This method relies on the use of less toxic, easily- handled reagents, and can be performed under milder conditions than offered by some conventional methods, affording 2,3-disubstituted-4-oxy-cyclopentan-l-one compounds enantio- and diastereoselectively, which are precursors to the said prostaglandin and prostaglandin analogs, in high yield.
