  • Crystal characteristics, preparation processes and anticancer applications of 17beta-neriifolin crystal forms
    Patent number: 11091510
    Abstract: The present invention provides the preparation processes for several crystal forms of the compound 17beta-Neriifolin (17bNF) and use thereof in anti-tumor applications. The present invention provides preparation processes for four kinds of non-solvated crystal forms, amorphous powders and eleven kinds of solvated crystalline solids, including ethanol-solvated ones, of 17bNF that are not present in nature, and the identification and characterization of these crystal forms by crystallographic research methods such as X-ray powder diffraction. In addition, through vivo anti-tumor experiments with five of the crystal forms in nude mice, we provide anti-tumor and anti-cancer applications of the crystal forms of 17bNF.
