Preparation method of teprenone

The invention belongs to the field of organic synthesis, and particularly relates to a preparation method of teprenone. The invention aims to solve the technical problems that the existing teprenone synthesis route is complicated, the stereo configuration of a synthesis precursor is difficult to control and the like. According to the method, alpha-farnesene, beta-farnesene, farnesol and nerolidol which are sourced from microbial fermentation are used for preparing a farnesyl acetone crude product, and then high-purity all-trans (5E, 9E)-farnesyl acetone is obtained through rectification, or all-trans (5E, 9E)-farnesyl acetone is directly synthesized from beta-farnesene and farnesol. Therefore, commercial teprenone with qualified quality can be obtained through subsequent reaction.

Cream containing teprenone and having red-removing effect and preparation method thereof

The invention relates to the field of cosmetic preparations, in particular to cream containing teprenone and having a red-removing effect and a preparation method of the cream. The cream is prepared from the following raw materials in parts by weight: 50 to 80 parts of water, 6 to 15 parts of a polyhydric alcohol humectant, 3 to 6 parts of an emulsifier, 10 to 25 parts of an emollient, 0.1 to 0.4 part of carbomer, 0.1 to 0.4 part of a pH regulator, 0.8 to 1.5 parts of a preservative and 0.05 to 1 part of teprenone-citric acid monoester. Through esterification modification of hydroxyl or amino sites of teprenone, the stability and transdermal absorption capacity of teprenone in a cream system are improved, so that the soothing, repairing and red-removing effects are enhanced. The prepared cream is free of layering and peculiar smell after being stored at 40 DEG C for 3 months, has good appearance and application stability, and is suitable for daily nursing of sensitive or reddish skin.

Compound of ursodeoxycholic acid or obeticholic acid and teprenone and its use in the preparation of a drug for preventing and treating liver fibrosis

The application discloses a complex of ursodeoxycholic acid or obeticholic acid and teprenone and application of the complex in preparation of a medicine for preventing and treating liver fibrosis. The combination of ursodeoxycholic acid or obeticholic acid and teprenone can significantly reduce the levels and contents of glutamic-pyruvic transaminase (ALT), glutamic-oxalacetic transaminase (AST) and hydroxyproline (Hyp) in model mice, thereby the effect of ursodeoxycholic acid or obeticholic acid in treating liver fibrosis can be enhanced. Therefore, the complex of ursodeoxycholic acid or obeticholic acid and teprenone has a potential for preventing and treating liver fibrosis, which is superior to ursodeoxycholic acid or obeticholic acid single component.
