4-Amino-1H-pyrazolo[3,4-d]pyrimidine derivatives of formula I
wherein the substituents are as defined in claim 1, are described.
These compounds inhibit the tyrosine kinase activity of the receptor for epidermal growth factor (EGF) and c-erbB2 kinase and can be used as anti-tumor agents.

The synthesis of novel 7-amino-substituted pyrazolo[1,5-a][1,3,5]triazine-8-carbonitriles was achieved via a three-component reaction of 3-amino-substituted 5-aminopyrazole-4-carbonitriles, cyanamide and triethyl orthoformate under microwave irradiation. Under catalyst-free conditions, this three-component reaction accommodated a generous diversity of amino substituents making it ideal for the generation
新型7-氨基取代的吡唑并[1,5- a ] [1,3,5]三嗪-8-腈的合成是通过3-氨基取代的5-氨基吡唑-4-腈的三组分反应实现的,微波辐射下的氰胺和原甲酸三乙酯。在无催化剂的条件下,该三组分反应可容纳大量的氨基取代基,因此非常适合用于药物开发过程的化合物库的生成。

The present application relates to substituted fused heteroaryl and heterocyclic compounds, useful as nicotinamide adenine dinucleotide phosphate oxidase inhibitors (NADPH oxidase inhibitors), processes for their preparation, pharmaceutical compositions comprising the compounds, and the use of the compounds or the compositions in the treatment or prevention of various diseases, conditions and/or disorders mediated by NADPH oxidase. (Formula I)
Several thieno[3,2-b]pyridines could be easily synthesized by methallation using LDA directly from 3-(disubstituted amino)-2-cyano-3-methylthioacrylonitriles.
In this work, we described the synthesis of new tetrasubstituted thiophenes and selenophenes achieved by an easy one-pot four-step procedure. Expected compounds were obtained in good yield from ketene dithioacetals.
