In the last decade the heat shock protein 90 (Hsp90) has emerged as a major therapeutic target and many efforts have been dedicated to the discovery of Hsp90 inhibitors as new potent anticancer agents. Here we report the identification of a novel class of Hsp90 inhibitors by means of a biophysical FAXS-NMR based screening of a library of fragments. The use of X-ray structure information combined with
在过去的十年中,热休克蛋白90(Hsp90)成为主要的治疗靶标,人们为发现Hsp90抑制剂作为新的有效抗癌药付出了许多努力。在这里,我们报告通过基于片段的文库的生物物理FAXS-NMR筛选新型Hsp90抑制剂的鉴定。X射线结构信息与建模研究相结合,使最初的三唑并喹唑啉的片段进化成为具有纳摩尔浓度和类似药物性质的化合物,适合进一步优化前导。
