Starting from capric acid, hydrazone and thiazolidin-4-one derivatives have been synthesized in the present investigation. Decanoic acid hydrazide was reacted appropriately to yield hydrazones, which were then cyclized to yield the corresponding thiazolidin-4-ones. The structures of the newly synthesized compounds were confirmed by analytical and spectral methods. Anti-inflammatory, analgesic, and hydrogen peroxide-scavenging activity of the title compounds were evaluated. Among synthesized compounds, 2-hydroxyphenyl thiazolidinone with 44.90% inhibition of inflammation was the most potent anti-inflammatory agent. Similarly, 4-methoxybenzylidine hydrazide with 64.90% inhibition of writhing was observed to be the most potent analgesic agent of the synthesized compounds. All the synthesized compounds exhibited potent hydrogen peroxide-scavenging activity.
Synthesis of some novel 2,5-disubstituted thiazolidinones from a long chain fatty acid as possible anti-inflammatory, analgesic and hydrogen peroxide scavenging agents
spectral methods. The anti-inflammatory, analgesic and antioxidant activity of the title compounds were evaluated. Compound 6j exhibited 44.84 % inhibition of inflammation and was the most potent anti-inflammatory agent of the series whereas compound 6f demonstrated the most potent analgesicactivity (69.82% inhibition of writhing) followed by compounds 6e and 6g. All the synthesised compounds exhibited
