  铁氨基自由基的位点选择性芳烃 C–H 胺化

  摘要：

  均聚芳族取代是芳烃 C-H 官能化的一种有利策略，具有许多重要的合成应用。然而，尽管取得了显着的进步，对位点选择性的控制仍然是一个艰巨的挑战。在这里，我们报告了使用铁氨基自由基对各种电子不同的芳烃进行统一的高度位点选择性芳烃C-H胺化。与传统使用的以氮为中心的自由基不同，金属负载的氨基自由基与芳烃底物中的各种固有官能团具有普遍的吸引力相互作用，通过底物螯合产生非凡的区域选择性。重要的是，这种方法能够克服极性和空间效应的固有影响，这些影响通常决定均解芳族取代中的区域化学控制，从而实现高位点选择性。适用的导向基团范围广泛，使该方法成为简化各种重要苯胺结构单元和药物合成的强大工具，并允许对结构多样的药物和其他生物活性分子进行后期 C-H 胺化。

  <p>Dexibuprofen amide derivatives as potential anticancer agents: synthesis, in silico docking, bioevaluation, and molecular dynamic simulation</p>

  摘要：

  Background: The amide derivatives of nonsteroidal anti-inflammatory drugs have been reported to possess antitumor activity. The present work describes the synthesis of dexibuprofen amide analogues (4a-j) as potential anticancer agents.Methods: The title amides (4a-j) were obtained by simple nucleophilic substitution reaction of dexibuprofen acid chloride with substituted amines in good yield and chemical structures were confirmed by FTIR, H-1 NMR, C-13 NMR and mass spectral data.Results: The brine shrimp lethality assay results showed that all of the synthesized compounds are non-toxic to shrimp larvae. The inhibitory effects on tumor growth were evaluated and it was observed that N-(2,5-dichlorophenyl)-2-(4-isobutylphenyl) propionamide (4e) and N-(2-chlorophenyl)-2-(4-isobutylphenyl) propionamide (4g) exhibited excellent antitumor activity compared to all other derivatives. The compound 4e bearing 2,5-dichloro substituted phenyl ring and 4g possesses 2-chioro substituted phenyl ring exhibited 100% inhibition of the tumor growth. The anticancer activity was evaluated against breast carcinoma cell line (MCF-7) and it was observed that derivative 4e exhibited excellent growth inhibition of cancer cells with IC50, value of 0.01 +/- 0.002 mu m, which is better than the standard drugs. The docking studies against breast cancer type 1 susceptibility protein BRCA1 (PDBID 3K0H) exhibited good binding affinities, which are in good agreement with the wet lab results. The compounds 4e and 4g showed the binding energy values of -6.39 and -6.34 Kcal/mol, respectively. The molecular dynamic (MD) simulation was also carried out to evaluate the residual flexibility of the best docking complexes of compounds 4e and 4g. The MD simulation analysis assured that the 4e formed a more stable complex with the target protein than the 4g. The synthesized amide derivatives exhibited were devoid of gastrointestinal side effects and no cytotoxic effects against human normal epithelial breast cell line (MCF-12A) were found.Conclusion: Based upon our wet lab and dry lab findings we propose that dexibuprofen analogue 4e may serve as a lead structure for the design of more potent anticancer drugs.

  Homolytic aromatic substitution is an enabling strategy for arene C–H functionalization with numerous important synthetic applications. However, despite notable advances, exerting control over site selectivity remains a formidable challenge. Here we report a unified highly site-selective arene C–H amination of various electronically distinct arenes using an iron-aminyl radical. Unlike the conventionally
