The invention discloses application of indeno triazine compounds as a substrate of quinone oxidoreductase depending on NAD (P) H. The indeno triazine compounds are catalyzed through the quinone oxidoreductase depending on the NAD (P) H to generate an oxidation reduction cycle reaction, a large number of reactive oxide free radicals are generated, strong oxidative stress is induced, and the obvious lethal effect on lung cancer, liver cancer, cervical cancer, pancreatic cancer, breast cancer, prostate cancer, nasopharynx cancer, kidney clear cell carcinoma, oral epidermoid carcinoma, chronic myelogenous leukemia, intestinal cancer, brain cancer, gastric cancer, esophagus cancer and other cancer cells expressed by the quinone oxidoreductase depending on the NAD (P) H is achieved. The indeno triazine compounds used as the substrate of the quinone oxidoreductase depending on the NAD (P) H can also be used as sensitizers for treating the cancer with radiotherapy, and have the obvious anticancer synergistic effect. In addition, the indeno triazine compounds used as the substrate of the quinone oxidoreductase depending on the NAD (P) H have antibacterial and antifungal activity.
