The synthesis of 54 3-phenacyl-5-benzylidene-thiazolidine-2,4-diones is reported. Eight of them were tested for anti-oedema, analgesic and anticonvulsant activity. Only one compound showed significant anti-oedematous and analgesic activity. Three compounds protected against tonic seizures and death.
Quantitative structure-activity relationships are described for twenty six title compounds. Five compounds exhibit a significant hypoglycemic activity like insulin used as standard. The aim of the present paper is to investigate the contribution of the different substituents in the biological activity. The application of Fujita-Ban and Hansch models has shown that lipophilic and electronic parameters seem to be the best explanation of variance of biological data.
