Specific interactions between Src homology 2 (SH2) domain-containing proteins and the phosphotyrosine-containing counterparts play significant role in cellular proteintyrosine kinase (PTK) signaling pathways. The SH2domain inhibitors could potentially serve as drug candidates in treating human diseases. Here we have incorporated a novel phosphotyrosine mimetic, which is an unusual amino acid carrying

The nitrile warhead used in a series of cathepsin K inhibitors can be replaced by a less electrophilic primary amide. The accompanying loss of potency can be partially recovered by introducing a substituent alpha to the amide. The potency gain resulting from this addition is not achieved with the nitrile derivatives due to a different geometry of the cysteine adduct in the enzyme active site. This

N‐Alkylated glycine oligomers (‘peptoids’) can serve as potent peptidomimetic systems. Installing different functional groups can often be a challenge, and minimizes yields and purities. Here, we describe the synthesis of different amide‐containing submonomers which were obtained as free bases, as well as their incorporation into peptoids. By using the free amines, the coupling results on solid support

N-to-C peptide ligation. Our model unites prebiotic aminonitrile synthesis and biological α-peptides, suggesting that short N-acyl peptide nitriles were plausible substrates during early evolution.Prebiotic peptide formation is achieved through chemoselective, high-yielding ligation of α-aminonitriles in water, showing selectivity for α-peptide coupling and tolerance of all proteinogenic amino acid residues
