Problems solved by technology

In recent years, some anti-hepatic fibrosis treatments have emerged, including chemical drugs, biological agents, traditional Chinese medicine and gene therapy, etc., but the ideal clinical treatment methods are still lacking (Liu Ping. Strengthen the research on the mechanism of anti-hepatic fibrosis. Chinese liver disease Magazine, 2005, 8(13): 561)

Embodiment 1

[0015] The preparation of embodiment 1 compound Atropurpuran

[0016] The preparation method of compound Atropurpuran (I) refers to the literature published by Pei Tang et al. (Pei Tang et al., 2009.Atropurpuran, a novel diterpene with an unprecedented pentacycliccage skeleton, from Aconitum hemsleyanum var.atropurpureum.Tetrahedron Letters50(2009)460-462 )Methods.

Embodiment 2

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

[0019] Compound I (312 mg, 1.00 mmol) was dissolved in 10 mL of benzene, 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 35 °C for 6 h. After 6h, 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 three 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 yellow powder of Compound II (309mg, 74%) .

Embodiment 3

[0024] The synthesis of O-(tetrahydropyrrolyl) ethyl derivative (III) of embodiment 3 Atropurpuran

[0025] Compound II (209 mg, 0.5 mmol) was dissolved in 18 mL of acetonitrile, anhydrous potassium carbonate (345 mg, 2.5 mmol), potassium iodide (84 mg, 0.5 mmol) and pyrrolidine (1420 mg, 20 mmol) were added thereto, and the mixture was heated to reflux for 2 h. After the reaction, the reaction solution was poured into ice water, extracted twice 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=100:1.0, v / v), and the concentrated brown elution band was collected and concentrated to give compound III as a brown solid (125 mg, 61%).

Abstract

The invention relates to the field of organic synthesis and medicinal chemistry and discloses and provides a composition formed by O-(tetrahydropyrrolyl) ethyl derivative (III) and O-(1H-tetranitroimidazolyl) ethyl derivative (IV) of Atropurpuran according to a mass ratio of 60:40 and a method of mixing the above compounds according to the mass ratio of 60:40 to prepare the composition. Pharmacological experiments show that the composition can remarkably inhibit NIH / 3T3 proliferation and transforming growth factor-beta 1 induced fibroblast proliferation when concentration is 20ug / ml and has anti-hepatic-fibrosis effect, so that the invention further provides application of the composition in preparing anti-hepatic-fibrosis medicine.

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] Liver fibrosis is a dynamic process from chronic liver injury to liver cirrhosis, manifested in the synthesis and secretion of a large amount of extracellular matrix (ECM), while the degradation is absolutely or relatively insufficient, resulting in the diffuse deposition of ECM in the liver. It starts with necrosis of hepatocytes (HC), followed by inflammatory response, release of fibrogenesis mediators, activation of hepatic stellate cells (FSC), and finally, the synthesis and degradation of liver connective tissue components are obviously out of balance. Liver fibrosis is a common pathological process of many chronic liver diseases and an important factor affecting prognosis. [0003] In the past 20 years, the study of liver fibrosis has made great progress, ...
