4 results about "Polyinosinic Acids" patented technology

The present disclosure relates to the technical field of medicine, and in particular to a pharmaceutical composition, preparation method and use thereof. The pharmaceutical composition includes a first active ingredient, a second active ingredient, and a pharmaceutically acceptable carrier or excipient. The first active ingredient is a microbial agent, including one or more of Staphylococcus aureus, Bordetella pertussis, diphtheria toxoid, tetanus toxoid, Salmonella typhi, and Salmonella paratyphi. The second active ingredient includes polyinosinic acid, polycytidylic acid, and vitamin. The pharmaceutical composition of the present disclosure pertains to an artificial active immunotherapy for tumors. It can “stimulate” the entire immune system, making the therapy of using bacteria to activate the human immune system to kill cancer cells highly stable and reliable. This composition can significantly save and prolong the lives of cancer patients while exhibiting extremely high safety, minimal toxic side effects, and low production costs.

The present invention discloses a pharmaceutical composition, its manufacturing method, and its use, wherein the pharmaceutical composition comprises a first active ingredient, a second active ingredient, and a pharmaceutically acceptable carrier or excipient, the first active ingredient being a microbial agent containing one or more of Staphylococcus aureus, Bordetella pertussis, diphtheria toxoid, tetanus toxoid, Salmonella typhi, or Salmonella paratyphi, and the second active ingredient comprising polyinosinic acid, polycytidylic acid, and vitamins. The pharmaceutical composition is an artificial active immunotherapy for tumors, which, by "stimulating" the entire immune system, activates the human immune system using bacteria to kill cancer cells, making the treatment extremely stable and reliable, significantly saving and extending the lives of cancer patients, while simultaneously being extremely safe, having very few toxic side effects, and having low manufacturing costs.

The invention provides application of taurochenodeoxycholic acid and / or chenodeoxycholic acid and polyinosinic acid combined medicine in preparation of medicine for preventing and / or treating melanoma, and belongs to the field of biological medicine. It is found for the first time that taurochenodeoxycholic acid and / or chenodeoxycholic acid can influence the tumor immune microenvironment by regulating and controlling the antigen presentation function of cDC1, and the treatment effect of polyinosinic-cytidylic acid is improved. The melanoma model experiment directly shows that the combination of chenodeoxycholic acid and polyinosinic-cytidylic acid can better inhibit tumor growth, can effectively promote CD8 + T cell infiltration in tumors, has more cDC1 infiltration in tumor tissues, shows a stronger inhibition effect on tumors, and can be used for preparing drugs for treating tumors. The pharmaceutical composition plays a synergistic role in treatment of melanoma, and provides a new choice for clinical treatment of melanoma.

Disclosed are pharmaceutical compositions formulated from immunomodulators formed from glycogen nanoparticles, such as monodisperse phytoglycogen nanoparticles, complexed with a pattern recognition receptor agonist, such as a TLR agonist which can be poly I:C. Also disclosed are methods of treating solid tumor cancers using the described immunomodulators, and uses of the immunomodulators to treat solid tumor cancers and to manufacture medicaments to treat solid tumor cancers.
