The invention provides application of a small molecule drug for promoting triple negative breast cancer ferroptosis, and belongs to the technical field of tumor treatment. The inducer can effectively kill triple negative breast cancer cells by triggering a ferroptosis pathway. The invention discovers that the inhibitor can reduce the expression of a key protein RPTOR by inhibiting the activity of an mTORCl compound, thereby weakening the anti-oxidation defense capability of triple negative breast cancer cells, greatly enhancing the accumulation of lipid peroxide, and further strongly inducing the occurrence of ferroptosis. The component of the culture medium is a DMEM (Dulbecco Modified Eagle Medium) containing 10% of fetal calf serum, and 2 [mu] M of Torinl is added at the same time. The invention discloses a new target spot of ferroptosis of the triple-negative breast cancer, and provides a new thought for treatment of the triple-negative breast cancer.

The invention belongs to the technical field of biological medicine, discloses a novel venom polypeptide composite dendrimer as well as a preparation method and application thereof, and particularly discloses scorpion venom polypeptide, and the amino acid sequence of the scorpion venom polypeptide is FLGGSLSSIF. According to the invention, a novel scorpion venom polypeptide (marked as C9) is separated and identified, and a novel polypeptide-polyamidoamine dendritic compound G5C9 (i.e., nanoparticles) with a glioblastoma (GBM) targeting effect is constructed. Compared with the polypeptide C9, the cell uptake efficiency of the G5C9 is obviously improved. G5C9 can enter cells through endocytosis and target lysosome to destroy functions of the lysosome and mTORC1, so that nuclear translocation of TFEB is promoted, and autophagic death of the cells is induced. Therefore, the G5C9 provides a novel mode for targeting the anti-GBM in vitro and in vivo.
