Abstract:

In this paper, new thiazolidinones, thiazinanones, and thiazolidinediones based on a monoterpenoid (-)-campholenic aldehyde were synthesized and their antiulcer and anti-inflammatory activity was investigated. The thiazolidinones and thiazinanones containing a (-)-campholenic moiety have been shown to possess antiulcerogenic properties in indomethacin-induced ulcer test comparable to the activity of the reference drug omeprazole. None of the investigated thiazolidinediones showed antiulcerative activity in the test. One of the (-)-campholenic aldehyde-derived thiazolidinones has also demonstrated high anti-inflammatory activity on the histamine-induced inflammatory edema model similar to the activity of diclofenac. It is shown that changing a (-)-campholenic substituent for a linear aliphatic or a terpenic fragment with a pinane scaffold results in decreasing the pharmacological properties, though the (-)-campholenic moiety does not seem to make a key contribution to the pharmacological activity. Compounds 11 and 17 have been shown to exhibit antiulcer and anti-inflammatory action at a dose of 100 mg/kg.
