  <p>Synthesis of budesonide conjugates and their anti-inflammatory effects: a preliminary study</p>

  摘要：

  Purpose: Budesonide (Bud) is a nonhalogenated glucocorticoid with high anti-inflammatory potency and low systemic side effects. However, the poor water solubility of Bud affects its dissolution and release behavior, thus influencing its anti-inflammatory effect. This study was aimed at synthesizing and evaluating novel conjugates of Bud, hoping to increase the anti-inflammatory activity of Bud by improving its water solubility.Materials and methods: Seven novel Bud conjugates (3a-3g) were designed and synthesized in this study. Besides, the equilibrium solubility, cell viability, in vitro and in vivo anti-inflammatory activity, and the hydrolysis behavior of the conjugates in different pH solutions, rat and human plasma, and rat lung homogenate were studied in detail.Results: As compared to Bud, the equilibrium solubility of 3a, 3c, and 3e was significantly increased; 3a, 3b, and 3c significantly inhibited the interleukin-6 production in lipopolysaccharide-induced A549 cells; 3a and 3e could significantly decrease the xylene-induced ear edema; and 3a and 3c were gradually and slowly hydrolyzed into Bud in the alveolar fluid and lung homogenate and broken down quickly in plasma.Conclusion: The amino acid ester compounds budesonide-21-glycine ester (3a) and budesonide-21-alanine ester (3c) were selected as potential conjugates of Bud. This study would provide a theoretical and an experimental basis for the in vivo process of glucocorticoids and the treatment of inflammatory diseases.
