title: Synthesis and biological evaluation of novel 2-[substituted acetyl]-amino-5-alkyl-1,3,4-thiadiazoles [corrected].
abstract: Sixteen novel 2-substituted acetyl amino-5-alkyl-1,3,4-thiadiazole were synthesized and screened for their pharmacological activities. A few of the compounds namely 11, 12 and 16 showed anti-inflammatory activities comparable to phenylbutazone. Compound 12 also showed significant non-specific spasmolytic activity. Diuretic activity of compound 15 at a dose level of 90 mg/kg p.o. was two fold higher compared to 50 mg/kg p.o. of furosemide. Comparable diuresis was also produced by compounds 9, 10 and 16.
