Curcumenol derivatives and application of curcumenol derivatives in preparing antitumor drug

The invention relates to curcumenol derivatives and application of the curcumenol derivatives in preparing an antitumor drug. By performing structure modification on the curcumenol derivatives, aftera furfuryl amine fragment is introduced at a hydroxy group site of curcumenol, amine is further introduced through Mannich reaction to obtain a series of the curcumenol derivatives of a structure of aformula (I) as well as pharmaceutically acceptable salts, hydrates, solvates or prodrugs of the curcumenol derivatives which are not reported. Verified by an in vitro bioactivity experiment, the newcurcumenol derivatives have the inhibitory activity to a cervical cancer, a liver cancer, a lung cancer and the like, and the compound activity of most of the new curcumenol derivatives are remarkablyhigher than that of curcumenol as a parent of the new curcumenol derivatives. In addition, the polarity of the vast majority of the synthesized curcumenol derivatives is remarkably improved comparedwith the curcumenol; according to the similarity and intermiscibility principle, the phenomenon that the solubility of the synthesized curcumenol derivatives is higher than that of the curcumenol of aparent compound is proved to a certain degree, and a basic theoretical basis is provided for better performing preparation research and exerting efficacy. The formula (I) is shown in the description.

Curcuma total sesquiterpene and tri-sesquiterpene monomer and preparation method and application thereof

ActiveCN107089992AExtend the range of action of the drugOrganic active ingredientsMetabolism disorderChromatographic separationEpoxy
The invention provides a curcuma total sesquiterpene and tri-sesquiterpene monomer as well as a preparation method and application on an aspect of resisting diabetes. A curcuma plant is taken as a raw material and is subjected to supercritical CO2 extraction or organic solvent extraction, then, low-polarity organic solvent is used for extraction to obtain a low-polarity total sesquiterpene extractive, and the low-polarity total sesquiterpene extractive is subjected to further chromatographic separation to obtain three types of sesquiterpene pure products of curcumenol, curdione and zedoary epoxy ketone. Activity research indicates that the total sesquiterpene, the curcumenol, the curdione and the zedoary epoxy ketone can be used for effectively increasing the consumption of glucose of HepG2 cells so as to obtain antidiabetic activity, and the total sesquiterpene, the curcumenol, the curdione and the zedoary epoxy ketone can be used for preparing antidiabetic medicines, antidiabetic health care food, functional foods and the like. The invention researches and develops new application of the diabetes resistance of the sesquiterpene in curcuma plants, the medicine function range of the curcuma plant is expanded, a basis is provided for carrying out popularization, utilization and deep processing on traditional Chinese medicinal materials, and a new application direction is provided.

Process for extracting curcumenol by molecular distillation method

The invention discloses a process for extracting curcumenol by a molecular distillation method. The process comprises the following steps of: adding zedoary oil into a feeding unit; firstly carrying out normal-temperature degassing under vacuum degree, and then opening condensed water and an oil-bath heater; after the temperature is stable, starting scraping-film stirring; then dripping the zedoary oil into a distiller; after the dripping is finished, collecting direct condensation fractions, external condensation fractions, unevaporated residual parts and degassed light components and losing; after the unevaporated residual parts are placed for one day, precipitating a great amount of crystals, using petroleum ether to carry out milliliter pulping, filtering, and drying to obtain white crystal; using alcohol with the mass concentration being 95% to recrystallize the crystal, and obtaining the curcumenol crystal with the gas chromatography GC being larger than 99%. The process disclosed by the invention has the advantages that according to the molecular distillation principle, the zedoary oil is treated by molecular distillation, the liquid part is condensed into liquid on an internal condenser by short-process distillation, then the discharged material is discharged, the zedoary oil can be rapidly separated from the curcumenol, and by combination with the recrystallizing technology, the curcumenol with high purity can be obtained.
