Synthesis and Evaluation of Anti-Inflammatory and Antitussive Activity of Hydantion Derivatives

1-Methylhydantion is a compound, which was isolated from Oviductus Ranae for the first time. In our study, we found that it showed good antitussive and anti-inflammatory activity. It is also the first report which illustrates the antitussive activity of hydantion derivative. A series of hydantion derivatives were synthesized and evaluated for their anti-inflammatory and antitussive activity in vivo. The pharmacological tests showed that compounds 7a, 7c and 7d have good anti-inflammatory and antitussive activity compared to Ibuprofen and codeine. Compound 7a in particular showed two-fold stronger anti-inflammatory activity than Ibuprofen.
