[0129] Under ice bath conditions, 2-propylamine (3.54 g, 0.06 mol) was slowly added dropwise to a solution of 4-fluoro-3-nitrobenzonitrile (5 g, 0.03 mol) in acetonitrile (40 mL), stirred for 5 min, and then placed in the solution. The reaction was refluxed in an oil bath at 120 °C for 1.5 h. After monitoring the completion of the reaction, dichloromethane (200 mL) and hydrochloric acid (200 mL, 1 mol / L) were added for extraction. The organic phase was collected, dried over anhydrous sodium sulfate, and concentrated to obtain compound I-1.

Abstract

The invention discloses an oxygen-containing five-membered heterocyclic compound, a synthesis method, a pharmaceutical composition and application thereof, and belongs to the technical field of medicines and preparation and application thereof. The oxygen-containing five-membered heterocycle has the biological activity of inhibiting the protein tyrosine phosphatase SHP2, can be used as a tool compound for researching the biological function relevance of the protein tyrosine phosphatase SHP2 in the cell signal transduction process, and provides a new means for preventing and treating cancers and metabolic and immune diseases.

Description

technical field [0001] The invention belongs to the technical field of medicine and its preparation and application, and specifically relates to a class of oxygen-containing five-membered heterocyclic compounds, a synthesis method, a pharmaceutical composition and uses. Background technique [0002] SHP2 is a non-receptor protein tyrosine phosphatase that exists widely in the body. It consists of two SH2 domains (N-SH2 and C-SH2), a catalytically active PTP domain and proline-rich acid groups and tyrosine phosphorylation tails. SHP2 acts as platelet-derived growth factor (PDGF), epidermal growth factor (EGF), fibroblast factor (FGF), interleukin-3 (IL-3), leukemia inhibitory factor (LIF) and α-interferon (INF) -α) and other downstream signaling molecules of growth factors, involved in multiple signaling pathways (such as RAS / MARK pathway, PI3K / AKT pathway, JAK / STAT pathway, JNK pathway, NF-B pathway, RHO pathway, NFAT pathway, etc.), in Plays a key role in cellular informa...
