    针对保守的水分子:使用基于片段的筛选和基于结构的优化设计4-芳基-5-氰基吡咯并[2,3- d ]嘧啶Hsp90抑制剂
    摘要:
    Hsp90分子伴侣的抑制剂有望作为抗癌药。在这里,我们描述了一系列的4-芳基-5-氰基吡咯并[2,3- d]嘧啶ATP竞争性Hsp90抑制剂,这些是通过基于NMR的专有片段文库筛选揭示的嘌呤命中结构驱动优化后鉴定的。配体-Hsp90的X射线结构与分子建模相结合,导致了保守水分子的合理置换,从而通过荧光偏振,等温滴定量热法和表面等离振子共振测定法测量了对Hsp90的亲和力。该取代是通过腈基实现的,是有效增加结合亲和力且分子量增加最小的一个例子。该化学系列中的某些化合物在体外抑制人癌细胞系的增殖,并导致致癌的Hsp90客户蛋白耗竭并伴随伴侣伴侣Hsp70升高。此外,一种化合物被证明在小鼠中具有口服生物利用度。这项工作证明了基于结构的设计对有效的Hsp90抑制剂快速进化的强大作用,以及在药物设计中考虑保守水分子的重要性。

    structures of Trypanosoma brucei methionyl-tRNA synthetase (TbMetRS) bound to inhibitors, we designed, synthesized, and evaluated two series of novel TbMetRS inhibitors targeting this parasite enzyme. One series has a 1,3-dihydro-imidazol-2-one containing linker, the other has a rigid fused aromatic ring in the linker. For both series of compounds, potent inhibition of parasite growth was achieved with
    基于与抑制剂结合的布鲁氏锥虫蛋氨酸-tRNA合成酶(Tb MetRS)的晶体结构,我们设计,合成和评估了针对该寄生虫酶的两种新型Tb MetRS抑制剂。一个系列具有包含1,3-二氢-咪唑-2-的接头,另一个系列在接头中具有刚性的稠合芳环。对于这两种化合物,当EC 50 <10 nM时,都可以有效抑制寄生虫的生长,并且大多数化合物对CC 50的哺乳动物细胞均表现出较低的一般毒性。s> 20 000 nM。还使用基于细胞的线粒体蛋白质合成测定法评估了对人类线粒体甲硫氨酸tRNA合成酶的选择性,并实现了20-200倍的选择性。这些抑制剂在血脑屏障上的渗透性较差,因此有必要进一步努力优化用于晚期人类非洲锥虫病的化合物。

    Inhibitors of the chaperone Hsp90 are potentially useful as chemotherapeutic agents in cancer. This paper describes an application of fragment screening to Hsp90 using a combination of NMR and high throughput X-ray crystallography. The screening identified an aminopyrimidine with affinity in the high micromolar range and subsequent structure-based design allowed its optimization into a low nanomolar series with good ligand efficiency. A phenolic chemotype was also identified in fragment screening and was found to bind with affinity close to 1 mM. This fragment was optimized using structure based design into a resorcinol lead which has subnanomolar affinity for Hsp90, excellent cell potency, and good ligand efficiency. This fragment to lead campaign improved affinity for Hsp90 by over 1,000,000-fold with the addition of only six heavy atoms. The companion paper (DOI: 10.1021/jm100060b) describes how the resorcinol lead was optimized into a compound that is now in clinical trials for the treatment of cancer.
