Luteolin

SKU: orb1310014

Description

Luteolin is a naturally occurring flavonoid that acts as an Nrf2 and PDE inhibitor. It exhibits a broad spectrum of bioactivities, including antitumor, anti-inflammatory, and antimicrobial effects, making it a valuable tool for in vitro and in vivo research in oncology, immunology, and pharmacology.

Bioactivity

• Target IC50:
  PDE1:15.0 μM (Ki)|PDE4:11.1 μM (Ki)|PDE5:9.5 μM (Ki)|PDE3:13.9 μM (Ki)|PDE2:6.4 μM (Ki)
• In Vivo:
  METHODS: To detect anti-tumor activity in vivo, Luteolin (50 mg/kg) was injected intraperitoneally once daily for eighteen days into BALB/C-nu mice bearing ESCC tumor EC1. RESULTS: The Luteolin treatment group showed a reduction in tumor size and a reduction in total tumor weight of about 65%. METHODS: To study the effect on intestinal mucositis, Luteolin (3-30 mg/kg in water plus 1% Tween) was administered by gavage or intraperitoneally to irinotecan-induced intestinal mucositis in Swiss mice once a day for fourteen days. RESULTS: Luteolin prevented irinotecan-induced intestinal damage by reducing weight loss and diarrhea scores as well as attenuating duodenal and colonic shortening.
• In Vitro:
  METHODS: ESCC cell lines EC1, EC9706, KYSE30 and KYSE450 were treated with Luteolin (10-80 µM) for 48-72 h. Cell viability was measured using the CCK-8 Assay. RESULTS: Luteolin inhibited the growth of ESCC cell lines in a dose-dependent manner with IC50 in the range of 20-60 µM. METHODS: Human cervical cancer cells, HeLa, were treated with Luteolin (5-20 µM) for 48 h. Cell cycle profiles were analyzed using Flow Cytometry. RESULTS: Luteolin treatment blocked the cell cycle progression of HeLa cells in sub-G1 phase.
