Four stereoisomers of oxy-peptide nucleic acids containing ether linkages in the main chain and conformationally-restricted pyrrolidine rings (pyrrolidine-based oxy-PNA = POPNA) were newly synthesized and investigated for binding to DNA. cis-L-POPNA with 9 adenine bases formed the most stable hybrid with dT9. The POPNA showed high sequence specificity similar to that of the Nielsen-type PNA and sharper melting behavior in hybridization with DNA than the Nielsen-type PNA.

G protein-coupled receptor 40 (GPR40) has become an attractive target for the treatment of diabetes since it was shown clinically to promote glucose-stimulated insulin secretion. Herein, we report our efforts to develop highly selective and potent GPR40 agonists with a dual mechanism of action, promoting both glucose-dependent insulin and incretin secretion. Employing strategies to increase polarity and the ratio of sp3/sp2 character of the chemotype, we identified BMS-986118 (compound 4), which showed potent and selective GPR40 agonist activity in vitro. In vivo, compound 4 demonstrated insulinotropic efficacy and GLP-1 secretory effects resulting in improved glucose control in acute animal models.

Propargyloxyproline Regio- and Stereoisomers for Click-Conjugation of Peptides: Synthesis and Application in Linear and Cyclic Peptides
Northfield, Susan E.,Mountford, Simon J.,Wielens, Jerome,Liu, Mengjie,Zhang, Lei,Herzog, Herbert,Holliday, Nicholas D.,Scanlon, Martin J.,Parker, Michael W.,Chalmers, David K.,Thompson, Philip E.

The use of the click reaction for the introduction of conjugate groups, such as affinity or fluorescent labels, to a peptide for the study of peptide biochemistry and pharmacology is widespread. However, the nature and location of substituted 1,2,3-triazoles in peptide sequences may markedly affect conformation or binding as compared with native sequences. We have examined the preparation and application of propargyloxyproline (Pop) residues as a precursor to such peptide conjugates. Pop residues are available in a range of regio- and stereoisomers from hydroxyproline precursors and are readily prepared in Fmoc-protected form. They can be incorporated routinely in peptide synthesis and broadly retain the conformational properties of the parent proline containing peptides. This is exemplified by the preparation of biotin- and fluorophore-labelled peptides derived from linear and cyclic peptides.

Direct asymmetric aldol reactions catalysed by trans-4-hydroxy-(S)-prolinamide in solvent-free conditions
Yadav, Geeta Devi,Singh, Surendra
, p. 1156 - 1166 (2015/10/28)
Direct asymmetric aldol reactions between 4-nitrobenzaldehyde and cyclohexanone were catalysed by trans-4-hydroxy-(S)-prolinamide (10 mol %) in the presence of CH3COOH (10 mol %) as the co-catalyst under solvent-free conditions at 15 °C. (2S,4R)-4-Hydroxy-N-((S)-1-phenylethyl)pyrrolidine-2-carboxamide 2 efficiently catalysed the asymmetric aldol reaction to afford the product in >99% yield and with 95% ee with an anti/syn ratio of 88:12 after 18 h. The additional trans-hydroxyl group on (S)-prolinamide and (S)-1-phenylethylamine both influenced the ee of the predominant anti aldol product. Different benzaldehyde derivatives with cyclohexanone gave the corresponding aldol products in 38-89% yields and with 56-94% ee with anti/syn (100:0-71:29). Catalyst 2 can be used up to 5 continuous cycles for asymmetric aldol reactions between 4-nitrobenzaldehyde and cyclohexanone with overall 91% yield and 86% yield of anti-product with anti/syn (98:2).
