The present invention relates to a method for reducing the production of methane emanating from the digestive activities of a ruminant and/or for improving ruminant animal performance by using, as active compound at least one organic molecule substituted at any position with at least one nitrooxy group, or a salt thereof, which is administrated to the animal together with the feed. The invention also relates to the use of these compounds in feed and feed additives such as premix, concentrates and total mixed ration (TMR) or in the form of a bolus.
The present invention relates to a-amino boronic acid derivatives. These compounds are useful for inhibiting the activity of immunoproteasome (LMP7) and for the treatment and/or prevention of medical contidions affected by immunoproteasome activity such as inflammatory and autoimmune diseases, neurodegenerative diseases, proliferative diseases and cancer.

Tunable and selective hydrogenation of the platform chemical 5‐hydroxymethylfurfural into valuable C6 building blocks and liquid fuel additives is achieved with copper‐doped porousmetaloxides in ethanol. A new catalyst composition with improved hydrogenation/hydrogenolysis activity is obtained by introducing small amounts of ruthenium dopant into the previously reported Cu0.59Mg2.34Al1.00 structure
通过在乙醇中掺杂铜的多孔金属氧化物,可以将平台化学物质5-羟甲基糠醛可调谐和选择性加氢成有价值的C 6结构单元和液体燃料添加剂。通过将少量钌掺杂剂引入先前报道的Cu 0.59 Mg 2.34 Al 1.00中,可获得具有改善的氢化/氢解活性的新型催化剂组合物。结构体。在温和的反应温度(100°C)下,获得2,5-呋喃二甲醇的选择性高达99%以上。较高的反应温度(220°C)有利于选择性脱氧为2,5-二甲基呋喃和次要产品2,5-二甲基四氢呋喃,总收率高达81%。值得注意的是,这些高产物收率维持在底物浓度高达10wt%和低催化剂负载下。探索了不同醇溶剂对产物选择性的影响。此外,鉴定了在不同反应温度下形成的反应中间体。这些产物混合物的组成提供了对影响产物选择性的还原途径的性质的机械见解。在反应之前和之后,通过元素分析,TEM和BET技术对催化剂进行表征。

Rhodium(II) acetate catalyzed decomposition of diethyl 4-diazo-2-pentenedioate resulted in the fomation of a vinylcarbenoid, which underwent formal [3 + 4] cycloaddition reactions with a series of furans. The most likely mechanism for these reactions involves cyclopropanation followed by a Cope rearrangement of the divinylcyclopropane intermediate.
