Room-temperature synthesis of 4-alkyl/aryl-2-aminothiazoles from vinyl azides and ammonium thiocyanate was accomplished with the aid of copper salts and blue LED irradiation. Mechanism investigation indicates that in situ-formed Cu(NCS)2– plays dual important roles in the reaction: (1) as the photocatalyst to activate vinyl azides, (2) as the Lewis acid catalyst to promote ring opening of 2H-azirines
This invention is directed to triazine derivatives, bicyclic compounds and tricyclic compounds which are selective antagonists for a NPY (Y5) receptor. The invention provides a pharmaceutical composition comprising a therapeutically effective amount of a compound of the invention and a pharmaceutically acceptable carrier. This invention provides a pharmaceutical composition made by combining a therapeutically effective amount of a compound of this invention and a pharmaceutically acceptable carrier. This invention provides a process for making a pharmaceutical composition comprising combining a therapeutically effective amount of a compound of the invention and a pharmaceutically acceptable carrier. The invention further provides the use of a compound of the invention for the preparation of a pharmaceutical composition for treating an abnormality, wherein the abnormality is alleviated by decreasing the activity of a human Y5 receptor.

Tricyclic thiazoleamine derivatives that were identified as hits in a screen against human umbilical vein endothelial cell proliferation were subjected to a structure-activity relationship study. Two structurally superimposable scaffolds-4H-thiochromeno[4,3-d]thiazol-2-amine and 5,6-dihydro-4H-benzo[6,7]cyclo hepta[1,2-d] thiazol-2-amine derivatives-yielded low-micromolar inhibitors, and two among them 37 and 43 also exhibited antiangiogenic activity in an endothelial tube formation assay. Thus, 37 and 43 can serve as leads to develop a novel class of antiangiogenic agents. (C) 2013 Elsevier Ltd. All rights reserved.
