  New chromene scaffolds for adenosine A2A receptors: Synthesis, pharmacology and structure–activity relationships

  摘要：

  In silico screening of a c ollection of 1584 academic compounds identified a small molecule hit for the human adenosine A(2A) receptor (pK(i) = 6.2) containing a novel chromene scaffold (3a). To explore the structure activity relationships of this new chemical series for adenosine receptors, a focused library of 43 2H-chromene-3-carboxamide derivatives was synthesized and tested in radioligand binding assays at human adenosine A(1), A(2A), A(2B) and A(3) receptors. The series was found to be enriched with bioactive compounds for adenosine receptors, with 14 molecules showing submicromolar affinity (pK(i) >= 6.0) for at least one adenosine receptor subtype. These results provide evidence that the chromene scaffold, a core structure present in natural products from a wide variety of plants, vegetables, and fruits, constitutes a valuable source for novel therapeutic agents.

  recyclable heterogeneous ionic liquid catalyst was synthesized. Catalytic activity of the CaO@SiO 2 @AIL hybrid nanoparticles was investigated for synthesis of the pharmaceutically valuable 2-imino-2 H- chromene and dihydropyrano[ c ]chromene derivatives. A wide range of amines and aromatic aldehydes containing either electron-withdrawing or electron-donating substituent were examined using optimized conditions
