Synthesis of (±)-Pisonivanone and Other Analogs as Potent Antituberculosis Agents
A new class of alkylated chalcones and flavanones was synthesised and screened for antituberculosis, antixoidant, and cytotoxic activities. The desired compounds were synthesised using methyl substituted 2-hydroxyacetophenone as a key intermediate. The acetophenone derivative having methyl substitut...

| description | A new class of alkylated chalcones and flavanones was synthesised and screened for antituberculosis, antixoidant, and cytotoxic activities. The desired compounds were synthesised using methyl substituted 2-hydroxyacetophenone as a key intermediate. The acetophenone derivative having methyl substitution was prepared in turn from methtylated phloroglucinol by formylation (by Vilsmeier-Haack reaction), followed by reduction with Wolf-Kishnner approach, and finally acetylation was involved. Among 17 compounds, compound 5 and compound 4a inhibited M. tuberculosis at minimum inhibitory concentration (MIC) in the range between 25 μg/mL and 50 μg/mL. The remaining other 15 compounds also potently inhibited M. tuberculosis at MIC in range between 50 μg/mL and 100 μg/mL. Some of these compounds also showed moderate antioxidant and cytotoxic activities. |
