Abstract
Non-proteogenic amino acids and functionalized peptides are important motifs in modern drug discovery. Here we report that AlaB can serve as universal building blocks in the synthesis of a diverse collection of modified amino acids, peptides, and proteins. First, we develop the synthesis of AlaB from redox-active esters of aspartic acid resulting in a series of β-boronoalanine derivatives. Next, we show that AlaB can be integrated into automated oligopeptide solid-phase synthesis. AlaB is compatible with common transformations used in preparative peptide chemistry such as native chemical ligation and radical desulfurization as showcased by total synthesis of AlaB -containing ubiquitin. Furthermore, AlaB reagents participate in Pd-catalyzed reactions, including C-C cross-couplings and macrocyclizations. Taken together, AlaB synthons are practical reagents to access modified peptides, proteins, and in the synthesis of cyclic/stapled peptides.

Abstract
Treatment of the protected (E)-5'-deoxy-5'-[(p-toluenesulfonyl)methylene]uridine and adenosine derivatives with tributyl- or triphenylgermane hydride (AIBN/toluene/Delta) effected radical-mediated germyldesulfonylations to give 5'-(tributyl- or triphenylgermyl)methylene-5'-deoxyuridine and adenosine derivatives as single (E)-isomers. Analogous treatment of 2'-deoxy-2'-[(phenylsulfonyl)methylene]uridine with Ph(3)GeH afforded the corresponding vinyl triphenylgermane product. Stereoselective halodegermylation of the (E)-5'-(tributylgermyl)methylene-5'-deoxy nucleosides with N-iodosuccinimide or N-bromosuccinimide provided the Wittig-type (E)-5'-deoxy-5'-(halomethylene) nucleosides quantitatively, while no halodegermylations was observed with the 5'-deoxy-5'-(triphenylgermyl)methylene counterparts. Treatment of the vinyl trialkylgermanes with aqueous trifluoroacetic acid effected protiodegermylation, while vinyl triarylgermanes were stable under the acidic conditions.

Abstract
The effect of substituting unnatural hydrophobic amino acids into the critical MHC binding residues of an HLA-A*0201-restricted cytomegalovirus CMVpp65 epitope, NLVPMVATV, has been investigated. A new set of peptides containing the amino acids tert-butyl glycine (Tgl), cyclohexyl glycine (Chg), neo-pentyl glycine (Npg), cyclohexyl alanine (Cha) and cyclo leucine (Cyl), at either position 2, to mimic Leu, or position 9, to mimic Val, have been synthesised. Immunological profiling using class I MHC stabilisation assays to assess MHC binding affinity, and enzyme-linked immunospot (ELISPOT) assays to assess the ability of the modified peptides to re-stimulate a specific cytotoxic T-lymphocyte (CTL) response, compared to the native epitope, have been performed. It was found that the majority of the unnatural substitutions resulted in a decrease in either HLA-A*0201 binding affinity or cytotoxic T-cell activity. However, the HLA-A*0201 binding affinity was unrelated to the ability to re-stimulate a T-cell response. Minimisation and molecular dynamics studies proved helpful in dissecting the ELISPOT responses. Two principal peptide binding modes were found by minimisation, designated kinked and straight. Peptides that bound in a kinked conformation were poor at re-stimulating a T-cell response. Of the peptides that bound in a straight conformation, molecular dynamics (MD) simulations revealed that those capable of re-stimulating the strongest responses had the greatest degree of flexibility (as determined by RMSD values across the MD simulation) around the P6 residue, one of the residues important for T-cell receptor recognition.

Abstract
Twofold sila-substitution (C/Si exchange) in the saturated ring of the tetrahydronaphthalene skeleton of the retinoid agonists TTNPB (1 a) and 3-methyl-TTNPB (2 a) leads to disila-TTNPB (1 b) and disila-3-methyl-TTNPB (2 b), respectively. The silicon compounds 1 b and 2 b were synthesized in multiple steps, and their identities were established by elemental analyses, multinuclear NMR experiments, and single-crystal X-ray diffraction studies. Like TTNPB (1 a) and 3-methyl-TTNPB (2 a), the analogous silicon-based arotinoids 1 b and 2 b are strong pan-RAR agonists and display the same strong differentiation and apoptosis-inducing activity in NB4 promyelocytic leukemia cells as the parent carbon compounds. These results are in keeping with the nearly isomorphous structures of 1 a and 1 b bound to the complex of the RARbeta ligand-binding domain with the nuclear receptor (NR) box 2 peptide of the SRC-1 coactivator. The contacts within the ligand-binding pocket are identical except for helix H11, for which two turns are shifted in the disila-TTNPB (1 b) complex. This study represents the first comprehensive structure-function analysis of a carbon/silicon switch in a signaling molecule and demonstrates that silicon analogues can have the same biological functionalities and conserved structures as their parent carbon compounds, and it illustrates at the same time that silicon analogues of biologically active compounds have the potential to induce alternative allosteric effects, as in the case of helix H11, which might allow for novel options in drug design.

Abstract
[reaction: see text] Silatranyluridine 1 and germatranyluridine 2 have been prepared in five steps from oxazolinouridine 3 in 27 and 29% yields, respectively. These compounds are novel transition-state analogues (TSAs) for RNA hydrolysis and offer a number of advantages over traditional vanadium- or rhenium-based TSAs. Germatrane 2 is completely stable in D(2)O at room temperature, and the half-life of silatrane 1 in D(2)O was found to be >7 days by (1)H NMR spectroscopy.
