Sofalcone (SU-88), a gastric antiulcer agent in clinical use, is known to induce the expression of Heme oxygenase-1 (HO-1) in gastric epithelium.

Sofalcone（50 μmol/L）显著提高了滋养细胞和HUVECs中HO-1 mRNA的表达，相较于对照组有显著差异（P<0.05）。Western blot分析显示，Sofalcone在24小时内显著增加了初级HUVECs中HO-1蛋白的表达。此外，Western blot分析还显示，Sofalcone处理6小时后HUVECs核分部中Nrf2的量显著增加。在初级HUVECs中，NQO1、TXN和GCLC的表达随Sofalcone处理的剂量增加而增加。Sofalcone显著降低了培养基中的sFlt-1浓度，并且剂量依赖性地减少了THP-1单核细胞对HUVECs的粘附。

Primary HUVECs are seeded at 60?000 cells per well and incubated at 37°C for 14 to 16 hours to allow tube formation. Cells are then cultured in the presence of either TNF-α (10 ng/mL) alone, with both TNF-α (10 ng/mL) and Sofalcone 50 μM, or control media for 8 to 12 hours. Tube formation is assessed, and images are captured using microscope at ×4 magnification.
