Cyclization is now a common strategy for improving pharmacological properties of a peptide from its linear precursor, including affinity and specificity, proteolytic stability, and/or solubility.
Our team has rich experience in cyclic peptide synthesis, with 100,000+ cyclic peptides successfully delivered.
Cyclization strategies include single/double/triple disulfide, click cyclization, lactone, lactam, RCM, etc. The cyclization positions can include head-to-tail, head-to-sidechain, sidechain-to-sidechain, sidechain-to-tail.
