Abstract: Provided is a utidelone liposome composition. The liposome composition mainly contains utidelone, a phospholipid, and optional cholesterol. The liposome composition does not contain an excipient that is prone to causing an allergic reaction of a human body, has a high drug loading capacity and stability, and has a good industrialization potential. Further provided are a method for preparing the utidelone liposome composition and the use thereof.

Abstract: Recombinant Sorangium cellulosum for producing de-epoxidized epothilone B by fermentation, insertional inactivation of an epoK gene in an epothilone biosynthetic gene cluster in the recombinant bacteria, and a method for producing de-epoxidized epothilone B using the recombinant bacteria.

Abstract: An oral pharmaceutical formulation using 4, 8-dihydroxy-5, 5, 7, 9, 13-pentamethyl-16-[1-methyl-2-(2-methyl-thiazole-4-yl)-ethenyl]]-oxacyclohexadec-13-ene-2,6-dione (utidelone) as an active ingredient, suitable for oral administration. The pharmaceutical formulation is a solid formulation such as tablets and capsules, and the pharmaceutical dosage form has good stability, in vitro dissolution behavior, and bioavailability.

Abstract: A polycrystal form of Utidelone, particularly relating to a semi-hydrated crystal form (A) of Utidelone, a preparation method therefor and a use of crystal Utidelone in preparation of a pharmaceutical composition, especially the use in preparation of a pharmaceutical composition for inhibiting tumor growth and treating solid tumors of mammals, especially human. The provided crystal form is stable and resistant to high temperature and high humidity, and the preparation method is diversified and simple, and is suitable for industrialized production of new medicines.

Abstract: The present application discloses a pharmaceutical preparation comprising a de-epoxidized epothilone derivative, and especially relates to a preparation formulation of a compound with reduced allergens and toxicity; and also relates to the use thereof in the treatment of tumours, especially the use thereof in the treatment of solid tumours that are resistant to and fail to respond to other conventional chemotherapeutic agents, as well as the use thereof in the treatment of cancers alone or in combination with other tumour drugs or auxiliary drugs.
