Animal and plant-derived guaiazulene (GA) has the characteristics of antimicrobial, antioxidant, anti-inflammatory, anti-allergic and low toxicity. Sodium guaiazulene sulfonate (GAS-Na), a water-soluble derivative of GA, also has the effects of anti-inflammatory, promoting epithelial cell growth and wound healing. However, the commercial active molecules GA and GAS-Na have poor stability to light and heat. Therefore, in order to explore the guaiazulene biomedical functional molecules with higher activity and stability, 2,2'-biguaiazulene (BGA) and (2,2'-biguaiazulene)-1,1'-disulfonic acid sodium (BGAS-Na) were synthesized. Compared with GA and GAS-Na, the antioxidant activities of BGA and BGAS-Na were evaluated, and their biological effects on NO release and cell viability of LPS-induced RAW 264.7 macrophages were studied. The results showed that BGA and BGAS-Na had better antioxidant capacity and improved stability compared with GA and GAS-Na; BGAS-Na had the best NO inhibition rate in the anti-inflammatory activity test (the IC50 value was 5.64 μg/ mL), which was better than that of the commercial molecule GAS-Na, and the inhibitory effect was dose-dependent. In addition, the four compounds did not affect the growth of macrophages and had low cytotoxicity. Therefore, BGAS-Na is expected to become a potential anti-inflammatory drug.
