Research interests

My main research focus is to understand the importance of natural bioactive peptide from plants and their application to modulate molecular receptors and enzymes. The research is designed to elucidate molecular mechanisms of bioactive circular cystine-rich peptides such as immune system modulation and to understand the underlying effects. Natural bioactive peptide ligands are identified using a bioassay-guided fractionation and their structure-function and bioactivity-structure relationship are studied by applying chemical synthesis and activity assignments. Promising ligand peptideds are improved to provide future drug candidates.
