  Design, synthesis and anticancer properties of isocombretapyridines as potent colchicine binding site inhibitors

  摘要：

  A series of novel isocombretapyridines were designed and synthesized based on a lead compound isocombretastatin A-4 (isoCA-4) by replacing 3,4,5-trimethoxylphenyl with substituent pyridine nucleus. The MTT assay results showed that compound 20a possessed the most potent activities against all tested cell lines with IC50 values at nanomolar concentration ranges. Moreover, 20a inhibited tubulin polymerization at a micromolar level and also displayed potent anti-vascular activity in vitro. Further mechanistic studies were conducted to demonstrate that compound 20a could bind to the colchicine site of tubulin,and disrupte the cell microtubule networks, induce G2/M phase arrest, promote apoptosis and depolarize mitochondria of K562 cells in a dose-dependent manner. Notably, 20a exhibited more potent tumor growth inhibition activity with 68.7% tumor growth inhibition than that of isoCA-4 in H22 allograft mouse model without apparent toxicity. The present results suggested that compound 20a may serve as a promising potent microtubule-destabilizing agent candidate for the development of therapeutics to treat cancer.

  available ketones. Mechanistic studies suggest that this Rh-catalyzed deoxygenative borylation of ketones goes through an alkene intermediate, which undergoes regiodivergent hydroboration to afford linear and branched alkylboronates. The different steric effects of PPh2Me and P(nBu)3 were found to be responsible for product selectivity by density functional theory calculations. The alkene intermediate

  在这里，我们报告了一种有效的铑催化酮脱氧硼酸化合成烷基硼酸酯，其中区域选择性可以通过选择配体来切换。直链烷基硼酸酯仅在 P( n Bu) 3存在下获得，PPh 2 Me 有利于支链烷基硼酸酯的形成。该协议还允许从现成的酮中获取 1,1,2-三硼酸酯。机理研究表明，这种 Rh 催化的酮类脱氧硼酸化反应经过烯烃中间体，该中间体经历区域发散硼氢化反应，得到直链和支链烷基硼酸酯。PPh 2 Me 和 P( n Bu) 3的不同空间位阻效应通过密度泛函理论计算发现是产物选择性的原因。烯烃中间体也可以依次进行脱氢硼酸化和硼氢化反应以提供三硼酸酯。

  tolerates aryl chlorides, fluorides, ethers, esters, amides, nitriles, and alkyl chlorides. The reaction is applied to late‐stage modifications of various densely functionalized medicinally relevant molecules. Preliminary mechanistic studies suggest that a rare enantioselective η2‐coordinating activation of ketone carbonyls is involved. This cross‐coupling‐like mechanism is expected to enable other challenging

• Mild Cu-Catalyzed Oxidation of Benzylic Boronic Esters to Ketones
  作者：James D. Grayson、Benjamin M. Partridge

  DOI：10.1021/acscatal.9b00992

  日期：2019.5.3

  The oxidation of benzylic boronic esters directly to the ketone is reported. This mild Cu-catalyzed method uses an ambient atmosphere of air as the terminal oxidant and is notably chemoselective. Oxidation of the C–B bond occurs selectively, even in the presence of unprotected alcohols. Initial investigation suggests the reaction proceeds through an alkylboron to Cu transmetalation, peroxide formation
