生物活性 | Quercetagetin (6-Hydroxyquercetin) is a flavonoid[1]. Quercetagetin is a moderately potent and selective, cell-permeablepim-1kinase inhibitor (IC50, 0.34 μM)[2]. Anti-inflammatory and anticancer properties. |
IC50& Target[2] | PIM1 0.34 μM (IC50) | PIM2 3.45 μM (IC50) | RSK2 2.82 μM (IC50) | PKA 21.2 μM (IC50) |
|
体外研究 (In Vitro) | Quercetagetin also inhibits PIM2, PKA, and RSK2 with IC50s of 3.45, 21.2, and 2.82 μM, respectively[2]. Quercetagetin (0.1, 1, 10, and 100 μM, 72 hours) inhibits growth of RWPE2 prostate cancer cells with average ED50is 3.8 μM[2].
Cell Viability Assay[2] Cell Line: | RWPE2 prostate cancer cells | Concentration: | 0.1, 1, 10, and 100 μM | Incubation Time: | 72 hours | Result: | Inhibited growth of RWPE2 prostate cancer cells with average ED50is 3.8 μM. |
|
体内研究 (In Vivo) | Quercetagetin significantly inhibits UVB-induced skin cancer development. Topical application of 4 or 20 nmol of Quercetagetin to mouse skin reduces tumor incidence by 32.0% and 46.7%, respectively[3].
Animal Model: | SKH-1 hairless mice model[3] | Dosage: | 4 or 20 nmol | Administration: | Topical application; 28 weeks | Result: | Inhibited UVB-induced skin tumorigenesis in SKH-1 hairless mice models. Delayed the development of tumors and reduced tumor volumes in an SKH-1 hairless mice model. |
