A ∼3500-member library of bidentate inhibitors against protein tyrosine phosphatases (PTPs) was rapidly assembled using click chemistry. Subsequent high-throughput screening had led to the discovery of highlypotent (Ki as low as 150 nM) and selectiveMptpBinhibitors, some of which represent the most potentMptpBinhibitors developed to date.

building blocks (key components in clickchemistry). We report herein a highly robust and efficient strategy for high-throughput synthesis of a 325-member azide library. The method is highlighted by its simplicity and product purity. The utility of the library is demonstrated with the subsequent “click” synthesis of the corresponding bidentate inhibitors against PTP1B.

This study reports an efficient and convenient click synthesis of novel series of chromene scaffold linked to 1,2,3 triazole ring and terminal lipophilic fragments. Structures of all newly synthesized compounds were well characterized by IR, 1H NMR, 13C NMR and elemental analyses. In vitro MTT cytotoxic screening was performed using staurosporine as a reference drug against three different types: aggressive

Protein kinases catalyze the phosphorylation of serine, threonine, tyrosine and histidine residues in proteins. Aberrant regulation of kinase activity has been implicated in many diseases including cancer. Thus development of new strategies for kinase inhibitor design remains an active area of research with direct relevance to drug development. Abelson (Abl) tyrosine kinase is one of the Src-family of tyrosine kinases and is directly implicated in Chronic Myelogenous Leukemia (CML). In this article, we have, for the first time, developed an efficient method for the construction of small molecule-based bisubstrate inhibitors of Abl kinase using click chemistry. Subsequent biochemical screenings revealed a set of moderately potent inhibitors, a few of which have comparable potency to Imatinib (an FDA-approved drug for treatment of chronic myeloid leukemia) against Abl.
蛋白激酶催化蛋白质中丝氨酸、苏氨酸、酪氨酸和组氨酸残基的磷酸化。激酶活性的异常调节与包括癌症在内的多种疾病有关。因此,激酶抑制剂设计新策略的开发仍然是一个活跃的研究领域,与药物开发直接相关。阿贝尔森(Abl)酪氨酸激酶是 Src 家族酪氨酸激酶之一,与慢性骨髓性白血病(CML)直接相关。在这篇文章中,我们首次利用点击化学方法开发出了一种构建基于小分子的 Abl 激酶双底物抑制剂的有效方法。随后的生化筛选发现了一组中等效力的抑制剂,其中一些抑制剂对 Abl 的效力可与伊马替尼(美国 FDA 批准用于治疗慢性髓性白血病的药物)相媲美。
