The epidermal growth factor receptor (EGFR) is a well?validated drug target for the treatment of non?small cell lung cancer. Here we present an optimization approach and preliminary structure?activity relationship for 1H?pyrrolo[2,3?b]pyridines as covalent irreversible mutant EGFR inhibitors. We synthesized a focused library to investigate the effect of different aromatic substituents in the 4?position of this scaffold, interacting with the gatekeeper. We determined the activity of the synthesized compounds mutant EGFR enzyme assays and determined the selectivity over the wild type.

Cytokinins, N6-substituted adenine derivatives, are plant hormones playing important roles in various processes in plant development. Furthermore, cytokinins and their derivatives are able to control mammalian cell apoptosis and differentiation. The aim of our study was the synthesis of 7-azaindole derivatives as cytokinin analogues with the Hartwig-Buchwald coupling reaction in order to evaluate their biological properties on human myeloblastic leukaemia cells (HL-60 cell line). All these compounds presented a cytotoxic activity on HL-60 cells especially the 4-phenylaminopyrrolo[2,3-b]pyridine and the 4-phenethylaminopyrrolo[2,3-b]pyridine.

Ligand compound for copper catalyzed aryl halide coupling reaction, catalytic system and coupling reaction
-
Paragraph 0047; 0053-0056; 0058, (2021/05/29)
The invention provides a ligand compound capable of being used for copper catalyzed aryl halide coupling reaction, the ligand compound is a three-class compound containing a 2-(substituted or non-substituted) aminopyridine nitrogen-oxygen group, and the invention also provides a catalytic system for the aryl halide coupling reaction. Thecatalytic system comprises a copper catalyst, a compound containing a 2-(substituted or non-substituted) aminopyridine nitrogen-oxygen group adopted as a ligand, alkali and a solvent, and meanwhile, the invention also provides a system for the aryl halide coupling reaction adopting the catalyst system. The compound containing the 2-(substituted or non-substituted) aminopyridine nitrogen oxygen group can be used as the ligand for the copper catalyzed aryl chloride coupling reaction, and the ligand is stable under a strong alkaline condition and can well maintain catalytic activity when being used for the copper-catalyzed aryl chloride coupling reaction. In addition, the copper catalyst adopting the compound as the ligand can particularly effectively promote coupling of copper catalyzed aryl chloride and various nucleophilic reagents which are difficult to generate under conventional conditions, C-N, C-O and C-S bonds are generated, and numerous useful small molecule compounds are synthesized. Therefore, the aryl halide coupling reaction has a very good large-scale application prospect by adopting the copper catalysis system of the ligand.
Cu(II)-catalyzed sulfonylation of 7-azaindoles using DABSO as SO2-Source and its mechanistic study

, (2020/06/23)
DABSO mediated sulfonylation of iodinated 7-azaindoles was achieved for the first time through sulfonylative Suzuki-Miyaura cross coupling (SMC) reaction under mild conditions giving good yields of sulfonylated 7-azaindole derivatives. Interestingly, control experiments suggest that present method involves in-situ generation of ArSO2 free radical followed by the key steps of SMC reaction. Scope of the reaction was explored with both electronically different and bulky group carrying boronic acids as coupling partner. The sulfonylation is scalable and occurred selectively at iodo group, irrespective of its position on azaindole. Moreover, the proposed mechanism has been supported by electron paramagnetic resonance (EPR) and density functional theory (DFT) calculations.

Paragraph 0019; 0041-0043; 0054-0056; 0067-0069, (2019/07/01)
The invention belongs to the field of medicinal chemistry, and concretely relates to a method for synthesizing Meriolin. The method comprises the following steps: 7-azaindole used as a raw material undergoes an oxidation reaction to generate an intermediate 2; the intermediate 2 undergoes a halogenations reaction to generate an intermediate 3; the intermediate 3 is subjected to a Friedel-Crafts acylation to generate an intermediate 4; and the amino group of the intermediate 4 is protected to obtain an intermediate 5, the intermediate 5 undergoes an alkylation reaction to generate an intermediate 6, and the intermediate 6 is cyclized to obtain the target products Merilin 10 and Meriolin 7. The method adopting the inexpensive 7-azaindole as the raw material has the advantages of simple operation steps, mild reaction conditions, avoiding the use of CO, high temperature, high pressure and expensive Pd catalytic reagent and hazardous chemicals, obtaining of the Meriolin 10 and Meriolin 7 ata high yield, and provision of a new idea for the synthesis of Meriolins series new derivatives.
