Abstract
Based on structure activity analysis of morphine related opiates, we have synthesized some novel benzopyran fused isoxazolidines (2a-e) and derived conformationally constrained β2,3,3-amino alcohols (3a-e), which were evaluated in vivo for their anti-nociceptive activity through acetic acid induced writhing test (peripheral) and formalin induced algesia (central). Results showed that, compound 2a possesses significant opioid agonist activity. Further, molecular docking analysis reveals that compound 2a binds to δ-opioid receptor (DOR) with comparatively better D-score than to μ (MOR) and κ (KOR) receptors. Compound 2a did not show any toxicity up to a 2000 mg kg-1 dose.
