5-Amidinoindoles as dual inhibitors of coagulation factors IXa and Xa
摘要:
Structural features of a 5-amidinoindole inhibitor of factor Xa, which displayed modest inhibition of factor IXa were varied to increase potency and improve selectivity for factor IXa. (C) 2004 Elsevier Ltd. All rights reserved.

Nanostructured CuO is synthesized in water using copper pincer complex as precursor without any stabilizing agent and characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray analysis (EDAX). The selected area electron diffraction (SAED) and magnetization measurements indicate lattice fringes spacing of 0.25 nm for (111) plane and ferromagnetic nature of the CuO nanoflakes, respectively. Benzimidazole undergoes N-arylation reaction with aryl halides in the presence of CuO nanoflakes and K2CO3 in N,N-dimethylacetamide (DMAc) at 120 degrees C. The reusability of the CuO nanoflakes is also tested and the results are found to be good. (C) 2015 Elsevier B.V. All rights reserved.
