  • Title: Synthesis and pharmacological evaluation of 1,3,4-oxadiazole bearing bis(heterocycle) derivatives as anti-inflammatory and analgesic agents.
    Author: Jayashankar B, Lokanath Rai KM, Baskaran N, Sathish HS.
    Journal: Eur J Med Chem; 2009 Oct; 44(10):3898-902. PubMed ID: 19423197.
    Abstract:
    A series of novel ether-linked bis(heterocycle)s have been synthesized via [3+2]-cycloaddition reaction of nitrile oxide with allyl alcohol followed by intramolecular 1,3-diploar cycloaddition reaction of nitrile imine with carbonyl group. All the newly synthesized compounds were screened for their anti-inflammatory and analgesic activities. Among the list of compounds (7a-k) studied, 7d, 7g, 7j, and 7k exhibited excellent activity comparable to ibuprofen and aspirin at the similar dosages.
