Short description of research profile

Structure-activity relationship studies of biologically active peptides; design, chemical synthesis and biological activity of substrates and inhibitors of physiologically important enzymes – matriptase-2, matriptase-1, furin and proteasome; peptide conjugates with antimicrobial and anticancer activity – design and chemical activity; design and chemical synthesis peptides with enhance oral bioavailability
