Embodiment 2

[0081] Embodiment 2: the synthetic preparation of compound of the present invention

[0082] The general formula compound I of the present invention can be according to the following scheme figure 1 To prepare, wherein the substituent R 8 , R 9 , R 10 The substituents in the compounds of general formula I are as defined above.

[0083]

[0084] Add compound A (3.5mmol) and compound B (7mmol) into a 50mL two-necked bottle, connect it to a reflux condenser, pump air, and protect it with nitrogen. After adding acetic anhydride (20 mL) and triethylamine (5 mL) via needle injection, the mixture was reacted under reflux for 6 hours. After the reaction, the reaction solution was slowly poured into a beaker filled with a large amount of ice water, and kept stirring, at which point solids were precipitated. After the mixture was filtered, the resulting solid was recrystallized from ethanol to give compound C.

[0085] Compound C (5.56 mmol), copper powder (28.8 mmol) and quino...

Abstract

The invention relates to phenanthrene and dihydrophenanthrene compounds and an application thereof. The phenanthrene or dihydrophenanthrene compounds can effectively inhibit inflammatory factors and also can inhibit NF (nuclear factor)-kappa B and MAPKs (Mitogen Activated Protein Kinase) signal channels. The compounds or medically acceptable salts, solvates, clathrate compounds or prodrugs thereof can be applied to serving as medicines for treating inflammations and also can be applied to serving as medicines for treating NF-kappa B and MAPKs signal channel related diseases.

Description

technical field [0001] The invention relates to novel pharmaceutically useful phenanthrene and dihydrophenanthrene compounds, and the application of these compounds in the preparation of medicines for treating inflammation and diseases related to NF-κB and MAPKs signaling pathways. Background technique [0002] Inflammation is the body's normal defense response process to endogenous or exogenous injury factors, mainly mediated by activated immune cells. Under normal physiological conditions, the inflammatory response is beneficial to the body. It can kill and kill invading pathogenic microorganisms, eliminate exogenous stimuli, and promote the repair and healing of damaged tissues. However, when the body's self-regulating ability is out of balance, it will The uncontrolled inflammatory response can lead to many diseases, such as arthritis, septic shock, type 2 diabetes, bronchial asthma and senile dementia. Early inflammatory responses lead to increased capillary permeabili...
