Vaccines against the SARS-CoV-2 virus are just becoming available. While this is good news for controlling the spread of the virus, there has not been as much success in developing therapeutic agents for treating patients infected with SARS-CoV-2. A significant... Read more
Alkyne containing amino acids are useful building blocks for preparing modified peptides. Utilizing Sonogashira coupling or 1,3-cycloaddition with azides, they can form cyclized structures, conjugate with labels or biomolecules, and form structurally diverse amino... Read more
Azide and alkyne containing amino acidsare useful building blocks for incorporating “click chemistry” into peptide synthesis. The copper(I) catalyzed 1,3-dipolar cycloaddition of azides with alkynes to form 1,4-substituted 1,2,3-triazoles is a convenient method for... Read more
De novo design of picomolar SARS-CoV-2 miniprotein inhibitors Longxing Cao, Inna Goreshnik, Brian Coventry, James Brett Case, Lauren Miller, Lisa Kozodoy,Rita E. Chen, Lauren Carter, Alexandra C. Walls, Young-Jun Park, Eva-Maria Strauch, Lance Stewart, Michael S.... Read more
Hess and Loeffler (K. Hess, et al., J. Proteome Res., 2020, Published Sept. 5, 2020) have published a review of how peptide libraries and microarrays can be utilized to rapidly detect immunogenic epitopes of pathogens. These epitopes can be used to rapidly develop... Read more
Covid-19 continues to be a major health problem. Research on the SARS-CoV-2 virus is continuing as potential vaccines are entering testing. These are some of the publications from July concerning SARS-CoV-2. Adaptive Evolution of Peptide Inhibitors for Mutating... Read more
Covid-19, caused by the SARS-CoV-2 virus, as yet does not have a proven vaccine or drug treatment to prevent infection. Researchers globally are studying the virus and its method of infection to develop effective vaccines and drug treatments. Listed below are a few... Read more

Beta-amino acids and beta-homo amino acids have related structures. In both, the amino group is attached to the second carbon atom from the acid group. The difference is in the carbon skeleton. Beta-amino acids have the same carbon skeleton as alpha-amino acids,... Read more
Synthesizing hydrophobic peptides is often difficult. Inter-chain hydrogen bonding in the hydrophobic regions causes poor solvation of the peptide chains and slowed reaction rates. Measures to disrupt this hydrogen bonding often significantly improve the purity and... Read more
Fmoc-(Fmoc-Hmb)amino acids were introduced in the 1990s to improve synthetic yields of difficult peptides, such as amyloid β, that form aggregates during synthesis. It had been noted that tertiary amide bonds in a peptide sequence prevent interchain hydrogen bonding.... Read more
Modifying a peptide to include polyethylene glycol (PEG) groups may improve solubility and bioavailability. Protein PEGylation can protect the protein from proteolytic degradation and increase its half-life in biological applications, decrease its antigenisity or... Read more
