title: Anti-inflammatory, analgesic and antiproteolytic activities of some novel thiadiazoles.
abstract: Eighteen novel acetyl salicyloyl/butyroyl mercapto 1,3,4-thiadiazoles have been synthesized and characterized by their elemental analyses, IR and PMR spectral studies. Their efficacy against carrageenin induced paw oedema was tested in albino rats of either sex at a dose of 100 mg/kg p.o. In vitro antiproteolytic activity of the compounds was assessed by determining their ability to inhibit trypsin induced hydrolysis of bovine serum albumin. Active anti-inflammatory compounds were tested for their analgesic activity against aconitine induced writhing in albino mice. Approximate LD50 values were also determined in albino mice.
