Technologies

SetLance exploits a tetra-branched (left) or di-branched (right) peptide format for the construction of long-lived molecules to be developed as new drugs.

 

Setlance technology is based on the design, synthesis and efficacy evaluation of new bioactive peptides.

Our most bioactive peptide molecules are branched: multimericity determines increased protease stability and avidity of binding.

Setlance has now well established experience in the field of antimicrobial peptides  and cancer-targeting peptides.

The proprietary antimicrobial peptide family has been scanned for in vitro and in vivo efficacy, toxicity in cells and animals, antibiofilm activity, antiinflammatory activity and efficacy when incorporated in nanosystems. 

Tumor targeting peptides, conjugated to chemotherapeutics resulted promising in in vitro and in vivo cancer killing, either in the free form and incorporated in nanosystems.

SetLance develops new lead peptide sequences, which are optimized, characterized in vitro, and eventually developed in the preclinical, and early clinical phases.
