ANTI-CANCER PHARMACEUTICAL COMPOSITION FOR TARGETING HEAT SHOCK PROTEIN 70, CONTAINING INDOLOQUINAZOLIDINE ALKALOID
摘要:
The present invention relates to: an anti-cancer pharmaceutical composition for targeting heat shock protein 70, containing an indoloquinazolidine alkaloid; and the like. The indoloquinazolidine alkaloid of the present invention inhibits the growth of tumors and inhibits the expression of HSP70 protein and the colony formation activity of cancer cells, and inhibits the growth of tumors in mouse models with xenografts of a cancer cell line and xenografts of patient-derived cancer, and inhibits the growth of cancer cells resistant to drugs such as pemetrexed, cisplatin, and paclitaxel, and thus is expected to be widely usable in the prevention and treatment of various types of cancer.
