P2Y1 receptor antagonists as novel antithrombotic agents
摘要:
The P2Y(1) and P2Y(12) purinergic receptors are responsible for mediating adenosine diphosphate (ADP) dependent platelet aggregation. Evidence from P2Y(1) knockout studies as well as from nucleotide-based small molecule P2Y(1) antagonists has suggested that the antagonism of this receptor may offer a novel and effective method for the treatment of thrombotic disorders. Herein, we report the identification and optimization of a series of non-nucleotide P2Y(1) antagonists that are potent and orally bioavailable. (C) 2008 Elsevier Ltd. All rights reserved.
CH-acids in EtOH at reflux conditions. The products were isolated and tested in vitro for antibacterial effects on Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Furthermore cytotoxic activity of the spiropyrans on non-small-cell lung cancer cells (A549 cells), a breast epithelial cancer cell line (MCF-7), human malignant melanoma cells (A375), prostate cancer cells (PC3 cells, LNCaP cells)

A convenient one-pot protocol was developed for the synthesis of spiro[indeno[2,1-c]pyridazine-9,4′-pyran]-3′,4-dicarbonitrile derivatives by the reaction of cyanoacetohydrazide, ninhydrin, malononitrile and various cyclic CH-acids under reflux condition in ethanol. No hazardous solvent or catalyst was used in this method. The main advantages of this procedure are the availability of starting materials
通过氰基乙酰肼,茚三酮,丙二腈和各种腈的反应,开发了一种方便的一锅法合成螺[茚并[ 2,1- c ]哒嗪-9,4'-吡喃] -3',4-二腈衍生物乙醇中回流条件下生成环状CH-酸。此方法未使用有害溶剂或催化剂。该方法的主要优点是可获得原料,非常高的收率和易于纯化。
Rh(III)-Catalyzed Intermolecular C–H Amination of 1-Aryl-1<i>H</i>-pyrazol-5(4<i>H</i>)-ones with Alkylamines
rhodium(III)-catalyzed intermolecular aromatic C–H amination directed by an intrinsic functionality of the substrate/product but also features aminating an existing drug with either primary or secondary N-benzoate alkylamines as the coupling partners.
