摘要： A polyfluoro-substituted aromatic heterocyclic derivative having the structure as represented by formula I or formula I′, wherein at least one of Ri 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 Aktl 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. Therefore, the compound may be used as an Akt inhibitor in the medicament for treating a cell proliferation-related solid tumour or blood cancer in the human or animal body.

摘要： The present invention provides a use of canagliflozin in preparation of an antitumor drug, especially in preparation of a drug for treating solid tumors. It has been proven through researches that canagliflozin has a significant down-regulation effect on immune checkpoint protein PD-L1 in various tumor cells and can effectively enhance the killing effect of T cells on tumor cells in a co-incubation model of T cells and tumor cells, thereby broadening a clinical application scope of the chemical drug canagliflozin in tumor immunotherapy. The present invention provides a new medical use of canagliflozin, and also provides new approaches and potential targets for the development of small molecular drugs based on PD-L1.

摘要： The present disclosure provides a use of a nicotinamide composition in preparation of a drug for treating hand-foot skin reaction (HFSR) induced by sorafenib, the composition being consisted of nicotinamide and sorafenib in a dosage ratio of 2:3. The composition provided by the present disclosure can alleviate the HFSR caused by excessive keratinization induced by sorafenib. This protective effect is achieved by inhibiting HB-EGF/SIRT1 pathway. The present disclosure provides a mechanism of sorafenib-induced HFSR, i.e., the excessive activation of the HB-EGF/SIRT1 pathway, thereby providing a theoretical foundation for clinical research of sorafenib-induced HFSR. The present disclosure also provides a drug that can effectively treat sorafenib-induced HFSR, thereby greatly broadening the clinical application of sorafenib. Nicotinamide is highly clinically feasible due to its moderate price, and thus can be prepared in any suitable formulation according to the requirements.
