Major Projects

Undertaken

Undergraduate Research, University of Peradeniya, Sri Lanka Advisor- Prof. Veranja Karunaratne

  • Investigation of the bioactivity and the chemistry of the Ageritina riparia which is an invasive plant to Sri Lanka. There has been one major study about the antifungal compounds in roots of this plant. In this research antioxidant, cytotoxic, phytotoxic, antifungal properties and the total phenolic content of the dichloromethane and methanol extracts of all parts of Ageritina riparia were investigated
  • Chemical proteomic analysis of palmostatin beta-lactone analogs that affect N-Ras palmitoylation
  • An alternative route to form a sphingosine acceptor via reductive elimination
  • An alternative route to oxidize 2-methylene oxetane without using dimethyldioxirane (DMDO)
  • Donor-acceptor behavior upon Lewis acid treatment to a 1,1dimethyl-4oxaspiro[2.3]hexane1,1dicarboxylate motifs
