Embodiment 1

[0015] The preparation of embodiment 1 compound Artalbicacid

[0016] The preparation method of compound Artalbicacid (I) refers to the method published by Antonella Maggio et al. (Antonella Maggio et al., 2011. Artalbicacid, asesquiterpenewithanunusualskeletonfromArtemisiaalba (Asteraceae) fromSicily.TetrahedronLetters, 52 (2011) 4543-4545).

[0017]

Embodiment 2

[0018] The synthesis of the O-bromoethyl derivative (II) of embodiment 2 Artalbicacid

[0019] Compound I (266 mg, 1.00 mmol) was dissolved in 10 mL of benzene, and tetrabutylammonium bromide (TBAB) (0.08 g), 1,2-dibromoethane (3.760 g, 20.00 mmol) and 6 mL of 50% sodium hydroxide solution. The mixture was stirred at 40 °C for 16 h. After 16 hours, the reaction solution was poured into ice water, extracted twice with dichloromethane immediately, and the organic phase solutions were combined. Then the organic phase solution was washed with water and saturated brine for 5 times successively, then dried with anhydrous sodium sulfate, and finally concentrated under reduced pressure to remove the solvent to obtain a crude product. The crude product was purified by silica gel column chromatography (mobile phase: petroleum ether / acetone=100:1.0, v / v), the brown concentrated elution band was collected and the solvent was evaporated to obtain a brown powder of Compound II (272mg, 73%...

Embodiment 3

[0024] The synthesis of the O-(diethylamino) ethyl derivative (III) of embodiment 3 Artalbicacid

[0025] Compound II (187mg, 0.5mmol) was dissolved in 15mL of acetonitrile, anhydrous potassium carbonate (345mg, 2.5mmol), potassium iodide (84mg, 0.5mmol) and diethylamine (1460mg, 20mmol) were added thereto, and the mixture was heated to reflux for 12h . After the reaction, the reaction solution was poured into ice water, extracted 4 times with an equal amount of dichloromethane, and the organic phases were combined. The combined organic phases were successively washed with water and saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to remove the solvent to obtain a crude product. The crude product was purified by silica gel column chromatography (mobile phase: petroleum ether / acetone=100:0.5, v / v), the brown concentrated elution band was collected and the solvent was evaporated to obtain a brown powder of compound III (111.3mg, 61% ...

Abstract

The invention relates to the fields of organic synthesis and medicinal chemistry, in particular to a composition, a preparation method and application of the composition in preparation of anti-inflammatory drugs. The invention discloses the composition and the preparation method thereof. A pharmacological experiment shows that the composition has the anti-inflammatory effect, and has the value for developing anti-inflammatory drugs.

Description

technical field [0001] The invention relates to the fields of organic synthesis and medicinal chemistry, in particular to a composition, a preparation method and an application thereof. Background technique [0002] Inflammation occurs locally but can also affect the whole body. Local clinical features are redness, heat, swelling, pain and dysfunction. Redness and heat are due to the expansion of local blood vessels and the acceleration of blood flow due to inflammation. Swelling is caused by local inflammatory hyperemia and exudation of blood flow components. The development of drugs with anti-inflammatory effects is of great significance for the verification of relief and pain relief. [0003] The existing drugs for the treatment of inflammation have the problems of high toxicity and low safety. It is of great value to find compounds or lead compounds from natural products and carry out structural modification to obtain their derivatives, so as to obtain potential drugs...
