The present invention relates to a novel class of (R)-4-(heteroaryl)phenylpropionic derivatives of formula (I), useful in the inhibition of the chemotactic activation induced by the fraction C5a of complement. Said compounds are useful in the treatment of pathologies depending on the chemotactic activation of neutrophils and monocytes induced by the fraction C5a of the complement. In particular, the compounds of the invention are useful in the treatment of autoimmune hemolytic anemia (AIHA), psoriasis, bullous pemphigoid, rheumatoid arthritis, ulcerative colitis, acute respiratory distress syndrome, idiopathic fibrosis, glomerulonephritis and in the prevention and treatment of injury caused by ischemia and reperfusion.
A one-pot method for synthesis of reduced graphene oxide-supported Cu-Cu<sub>2</sub>
O and catalytic application in tandem reaction of halides and sodium azide with terminal alkynes
(Cu‐Cu2O@RGO) was prepared through a one‐pot reflux synthesis method. The morphology, crystal structure and composition of the prepared Cu‐Cu2O@RGO were characterized using transmission electron microscopy, X‐ray diffraction, and X‐ray photoelectron, infrared and Raman spectroscopies. Cu‐Cu2O@RGO as a heterogeneous catalyst was applied to tandem reactions of halides and sodium azide with terminal alkynes
还原氧化石墨烯(RGO)负载的Cu–Cu 2 O纳米复合材料(Cu‐Cu 2 O @ RGO)是通过单锅回流合成方法制备的。使用透射电子显微镜,X射线衍射,X射线光电子,红外和拉曼光谱学对制备的Cu‐Cu 2 O @ RGO的形态,晶体结构和组成进行了表征。Cu-Cu 2 O @ RGO作为非均相催化剂被用于卤化物和叠氮化钠与末端炔烃的串联反应,以有效合成1,4-二取代的1,2,3-三唑。而且,该催化剂显示出极好的可回收性,几乎没有金属的浸出。与均相催化剂相比,Cu‐Cu 2O @ RGO是一种绿色高效的催化剂,在串联方法合成1,2,3-三唑化合物时可回收,易于分离且高度稳定。
Polymer-Supported 1,5,7-Triazabicyclo[4.4.0]dec-5-ene as Polyvalent Ligands in the Copper-Catalyzed Huisgen 1,3-Dipolar Cycloaddition
New supportedcatalysts for the Huisgen’s [3+2] azide‐alkyne cycloaddition have been prepared by immobilization of copper species on commercially available polymeric matrixes incorporating the 1,5,7‐triazabicyclo[4.4.0]dec‐5‐ene (TBD) template. The synergic exploitation of the exceptional copper chelating ability and basicity profile of the TBD framework, in addition to ensuring effective immobilization

CuI-zeolites proved to be an efficient heterogeneous catalyst for the one-pottwo-stepsynthesis of triazoles from halides or tosylates, sodium azide, and alkynes. The step and atom economies of this cascade reaction as well as water used as solvent and catalyst recycling make such synthesis a trully green process. With selected substrates, the peculiar roles of CuI-zeolites as catalysts were highlighted
1,2,3-Triazoles were synthesized in water using a cheaper, simple and easily recyclable heterogeneous porous Cu catalyst via one-pot multi component reaction. The catalyst can be recycled five times without significant loss of its catalytic activity.
