使用组合化学和合成寡核苷酸创建的 DNA 编码小分子文库正被应用于制药行业的药物发现项目。大多数报道的项目描述了可逆的,即非共价的目标调节剂的发现。我们合成了多个以亲电试剂终止的 DNA 编码化学文库,然后使用它们来发现共价不可逆抑制剂,并报告成功发现了丙烯酰胺和环氧化物终止的布鲁顿酪氨酸激酶 (BTK) 抑制剂。我们还使用一系列技术证明了它们的选择性、效力和共价半胱氨酸的参与,包括 X 射线晶体学、热转换位移分析、报告基因置换分析和完整蛋白质复合物质谱。

potent, and kinome selective inhibitors of transforming growth factor β-activated kinase 1 (TAK1). The target was subjected to a DNA-encoded chemical library (DECL) screen. After hit analysis a cluster of compounds was identified, which was based on a central pyrrole-2,4-1H-dicarboxamide scaffold, showing remarkable kinome selectivity. A scaffold-hop to the corresponding imidazole resulted in increased biochemical

The present embodiments relate to compounds with physiological effects, such as the activation of hematopoietic growth factor receptors. The present embodiments also relate to use of the compounds to treat a variety of conditions, diseases and ailments such as hematopoietic conditions and disorders.
The present invention relates to compounds of the formulae I and Ia,
wherein R0 ; R1 ; R2 ; R3 ; R4; R22, Q; V, G and M have the meanings indicated in the claims. The compounds of the formulae I and Ia are valuable pharmacologically active compounds. They exhibit a strong antithrombotic effect and are suitable for the therapy and prophylaxis of cardiovascular disorders like thromboembolic diseases or restenoses. They are reversible inhibitors of the blood clotting enzymes factor Xa (FXa) and/or factor VIIa (FVIIa), and can in general be applied in conditions in which an undesired activity of factor Xa and/or factor VIIa is present or for the cure or prevention of which an inhibition of factor Xa and/or factor VIIa is intended. The invention furthermore relates to processes for the preparation of compounds of the formulae I and Ia, their use, in particular as active ingredients in pharmaceuticals, and pharmaceutical preparations comprising them.

The self-assembly of 2-(guanidiniocarbonyl)-pyrrole-4-carboxylate (2), which is a heteroditopic zwitterion with self-complementary binding groups, was studied in DMSO. Through intermolecular ion pairing between the carboxylate of one and the guanidinium group of another molecule, 2 forms linear chain like oligomers in solution as can be seen from the corresponding shift changes in the NMR spectrum
