title: Synthesis and antiinflammatory activity of heterocyclic indole derivatives.
abstract: Chalcones of indole 1-5 and their corresponding products; pyrazolines 6-10 and azo compounds 11-15 were synthesised and evaluated for their antiinflammatory activity against carrageenan induced oedema in albino rats at a dose of 50 mg x kg(-1) oral. The structure of compounds was confirmed by IR, (1)H-NMR and mass spectral data. All the compounds of this series showed promising antiinflammatory activity. The most active compound of this series is 3-[1-acetyl-5-(p-hydroxyphenyl)-2-pyrazolin-3-yl]indole (7) was found to be most potent, which has shown higher percent of inhibition of oedema, lower ulcerogenic liability and acute toxicity than the standard drug phenylbutazone.
