An accessible bicyclic architecture for synthetic lectins.

چکیده
Bicyclic carbohydrate receptors are easier to synthesise than tri- or tetra-cyclic relatives, and are better adapted to bind monosaccharide residues with bulky appendages. Disaccharides containing β-glucosyl units are preferred substrates.

Subunit disassembly and inhibition of TNFα by a semi-synthetic bicyclic peptide
Macrocyclic peptides are potentially a source of powerful drugs, but their de novo discovery remains challenging. Here we describe the discovery of a high-affinity (Kd = 10 nM) peptide macrocycle (M21) against human tumor necrosis factor-alpha (hTNFα), a key drug target in the treatment of inflammatory disorders, directly from diverse semi-synthetic phage peptide repertoires. The bicyclic pepti...
متن کاملRemote C–H insertion of vinyl cations leading to cyclopentenones† †Electronic supplementary information (ESI) available. See DOI: 10.1039/c7sc02768k Click here for additional data file.
We report a Lewis acid catalyzed reaction sequence involving a 1,2-shift and subsequent C–H insertion that gives monocyclic and fused bicyclic cyclopentenone products. This reaction sequence, which is initiated by treating b-hydroxy-a-diazo ketones with a Lewis acid, proceeds through vinyl cation intermediates that insert at non-activated gamma C–H bonds. This reaction represents an alternative...

متن کاملFlexible access to conformationally-locked bicyclic morpholines.
A preparatively accessible route to a series of conformationally-locked bicyclic morpholines has been developed. This flexible approach allows for diversification in order for a small array of lead-like scaffolds to be synthesised from readily available key building blocks.
متن کاملExpanding the accessible chemical space by solid phase synthesis of bicyclic homodetic peptides.
Norbornapeptides (bicyclo[2.2.1]heptapeptides) and related bicyclic homodetic peptides were prepared by solid-phase peptide synthesis using an orthogonal protection scheme. These conformationally rigid peptides cover an almost pristine area of peptide topological space and adopt globular shapes similar to those of short α-helical peptides.
