Uses of ergosterol combined with gefitinib, preparation methods of liposome and freeze-dried powder thereof
The present disclosure relates to a drug combination for treating non-small cell lung cancer, in particular to uses of ergosterol combined with gefitinib, and belongs to the technical field of biomedicine. In the present disclosure, the mechanism of action that ergosterol (ERG) combined with gefitinib (GEF) induces apoptosis of non-small cell lung cancer (NSCLC) cells is firstly studied; then an RGG cyclic peptide/R8 peptide modified ERG combined with GEF active drug-loaded targeted liposome delivery system (RGD/R8-ERG/GEF-LIP) is constructed; and the RGD/R8-ERG/GEF-LIP is prepared into a freeze-dried powder to improve stability, quality evaluation and preliminary evaluation of in vitro anti-lung cancer effects are conducted, and a nude mouse lung cancer xenograft model is established for conducting preliminary pharmacodynamic research and in vivo targeting research.
