  新型芳香族磺酰基萘基硼酸酯作为20S蛋白酶体抑制剂

  摘要：

  开发了一系列新的非肽蛋白酶体抑制剂（PIs），可作用于蛋白酶体的胰凝乳蛋白酶样（ChT-L）。在初步的生物学活性测试中，这些带有4-芳族磺酰基萘基支架和Leu-硼基作为共价键的PI表现出比PI-8182更好的抑制ChT-L的活性。结果表明，2a中（IC 50  = 6.942μM，MCF-7）和图2c（IC 50  = 6.905μM，MCF-7）显示更高的抗增殖活性要比硼替佐米（IC 50  = 18.37μM，MCF-7）根据我们的实验条件。此外，在微粒体稳定性测定中，2a表现出优异的代谢稳定性，40分钟后剩余56％，而Bortezomib则剩余约30％。化合物2a，2c作为有希望的先导化合物出现，用于开发新型非肽硼酸酯PI。

  Disclosed herein is the use of HLM-008182, as well as its analogues formed via in-house synthesis, as a potent proteasome inhibitors. A new method was developed for HLM-008182 through a four-step protocol and the method was further optimized to a two step protocol. The synthesis in both protocols was regioselective with TiCl 4 . The reaction was highly efficient with microwave assisted heating and THF as solvent. The modification around the molecule HLM-008182 established primary SAR, indicating that the proteasome inhibition activity was a function of the 2-side chain.

  A strategy allowing the switchable divergent synthesis of chiral indole derivatives was established via chiral phosphoric acid-catalyzed asymmetric dearomatization of 2,3-disubstituted indoles using naphthoquinone monoimines as electrophiles. The products were switched between chiral indolenines and fused indolines according to the post-processing conditions. Both two types of products were obtained

  The BRAF oncoprotein is mutated in about half of malignant melanomas and other cancers, and a kinase activating single valine to glutamate substitution at residue 600 (BRAF(V600E)) accounts for over 90% of BRAF-mediated cancers. Several BRAF(V600E) inhibitors have been developed, although they harbor some liabilities, thus motivating the development of other BRAF(V600E) inhibitor options. We report here the use of an ELISA based high-throughput screen to identify a family of related quinolol/naphthol compounds that preferentially inhibit BRAF(V600E) over BRAF(WT) and other kinases. We also report the X-ray crystal structure of a BRAF/quinolol complex revealing the mode of inhibition, employ structure-based medicinal chemistry efforts to prepare naphthol analogues that inhibit BRAF(V600E) in vitro with IC50 values in the 80-200 nM range under saturating ATP concentrations, and demonstrate that these compounds inhibit MAPK signaling in melanoma cells. Prospects for improving the potency and selectivity of these inhibitors are discussed.
