    Area of Science:

    • Medicinal Chemistry
    • Pharmacology

    Background:

    • Inflammation is a complex biological response implicated in various diseases.
    • Development of novel anti-inflammatory agents is crucial for therapeutic advancements.

    Purpose of the Study:

    • To synthesize and evaluate novel compounds with acenaphthene and indan parent nuclei for anti-inflammatory properties.
    • To assess the efficacy of these novel compounds in established animal models of inflammation.

    Main Methods:

    • Synthesis of acenaphthene and indan derivatives.
    • Testing anti-inflammatory activity using carrageenan-induced rat paw edema.
    • Evaluating efficacy in a rat adjuvant arthritis model.

    Main Results:

    • 1-phenyl-5-acenaphthenylacetic acid and its alpha-methyl derivative demonstrated activity in the carrageenan rat paw edema model.

  • Alpha-methylacenaphthenylacetic acid and 2-(4-chlorobenzylidene)-3-oxo-5-indanacetic acid derivatives showed activity in the rat adjuvant arthritis model.
  • No synthesized compound exhibited superior anti-inflammatory activity compared to control drugs phenylbutazone and indomethacin.

    • Conclusions:

    • Acenaphthene and indan scaffolds can be modified to yield compounds with anti-inflammatory potential.
    • Further optimization is needed to develop compounds with enhanced efficacy exceeding current standards.
