  • Publication number: 20230029066
    Abstract: Disclosed in the present disclosure are crystal forms of a fused ring compound, and a composition thereof, a preparation method therefor and use thereof. The crystal forms comprise a crystal form I, a crystal form II, a crystal form III, a crystal form IV and a crystal form V, which have, when using X-ray diffraction, characteristic diffraction peaks at about 11.3 degrees, 17.2 degrees and 21.1 degrees, at about 25.1 degrees, 21.2 degrees and 14.1 degrees, or at about 6.6 degrees, 13.4 degrees and 8.0 degrees, at about 11.8 degrees, 13.3 degrees and 16.7 degrees, and at about 6.5 degrees, 13.3 degrees and 20.0 degrees. The crystal form I or IV is obtained by dissolving a fused ring compound in a proper solvent, followed by stirring, filtering and drying. The use of crystal form I or crystal form IV in preparation of anti-cancer drugs for inhibiting phosphatidylinositol 3-kinase. The use thereof for targeted therapy for tumors, and for anti-inflammation or treatment of autoimmune diseases.

  • Patent number: 11319300
    Abstract: A polyfluoro-substituted aromatic heterocyclic derivative having the structure as represented by formula I or formula I?, wherein at least one of R1 and R2 is a fluorine atom, and at least two substituents of Rc, Rd, Re, and Rf are fluorine atoms; and an optical isomer of the derivative, or a pharmaceutically acceptable salt or solvate of the same, or a pharmaceutically acceptable salt or solvate of the optical isomer of the same. A composition containing the polyfluoro-substituted aromatic heterocyclic derivative and an application of the composition in preparing an anti-tumour medicament. The compound provides significant inhibitory effects with respect to Akt1 and demonstrates strong proliferation inhibitory activity with respect to tumour cell lines such as an ovarian cancer cell line, a colon cancer cell line, and a prostate cancer cell line.
