We offer Fmoc-protected unnatural amino acids for synthesis of peptides for biological
research and pharmaceutical development. By introducing conformational constraints, the
peptides may have one or several of the following features: 1. enhancement of peptide
backbone helicity for better target binding; 2. tunable hydrophobicity for desired cellular
permeability and cytotoxicity; and 3. enhancement of peptide stability against proteolytic
breakdown.
We offer nucleosides with modifications at the pyrimidine or purine base, such as 6-
Thioguanine, 7-Deazaadenine, 7-Deazaguanine, 8-Azidoadenine, 8-Bromoinosine and 8-
Iodoadenine, and, at the sugar such as 5'-Azido-5'-deoxythymidine, 2'-Azido-2'-deoxyuridine
and 2'-Azido-2'-deoxy-5-methyl uridine.
