A new reagent for click bioconjugation

A recent communication in Organic and Biomolecular Chemistry reports the synthesis of a new reagent for the introduction of alkynes into proteins; a key step for click bioconjugation. The new diazonium reagent was prepared in a one-pot synthesis from commercially available 4-ethynylaniline.

Having optimized bioconjugation in a tyrosine containing small molecule, the new diazonium reagent was then used to covalently label proteins. Fluorescence labelling of protein surface tyrosine residues was achieved under mild conditions (pH 8.0) by reaction of the protein with the diazonium reagent and subsequent reaction with an azide-containing fluorescent compound. The new diazonium reagent was also used to achieve protein PEGylation; a strategy that could be employed to improve protein stability and reduce immunogenicity.

The new diazonium reagent can facilitate bioconjugation in a range of proteins and could be a useful addition to the biochemist’s toolbox.

Diversification of a Multicomponent Reaction

The Ugi reaction was one of the very first multicomponent reactions exploited to develop chemical libraries, which further extended to combinatorial, solid phase and flow synthesis for evolving new lead structures of active agents. Implementing the Ugi reaction in combination with other organic reactions enlarges the chemical diversity of possible products.

Researchers at Vrije University Brussel, led by Steven Ballet, have made a step forward by executing a one-pot Ugi-Huisgen tandem reaction and found an alternative high atom economy pathway for the synthesis of conformationally constrained, amino-triazoloazepinone-containing di- and tripeptides.

Strategically, they have used an unconventional azide containing acid, and alkyne amine along with traditional aldehydes and isocyanides. By using equimolar reactants with very mild reaction conditions, they were able to observe total conversion to the linear Ugi-compounds equipped with azide and alkyne functionality. Furthermore, they have cyclised the resulting compounds into the respective triazoles, by performing a catalyst-free Huisgen cycloaddition reaction in a sealed tube.

Variation in substitution patterns and tolerance of a large array of aldehydes in this methodology will open a new avenue for the synthesis of various building blocks to be used in peptidomimetics with a wide range of applications.

Vaccines for heroin

The number of deaths due to heroin overdoses has severely increased in last decade, and regular consumption of heroin leads to serious health concerns.

Vaccination is one of the emerging choices among heroin rehabilitation therapies. In general, these vaccines contain heroin-like hapten as a pharmacophore that acts as an antagonist. This antagonist has high affinity for heroin receptors but does not activate them, hence reverses the effects of heroin. Because of inherent chemical instability, when entered in to bloodstream these anti-heroin drugs rapidly metabolise into several by-products, which makes development of effective vaccines against heroin particularly challenging.

Recently an American research group at National Institute on Drug Abuse (NIDA) lead by Professor Kenner Rice has reported the synthesis and immunological evaluation for a series of haptens.

The team has emphasised the hydrolytic stability of hapten scaffolds and envisioned that hapten with amido groups at both the C3 and C6 positions should be more stable than a hapten with an ester in one of those positions. Insertion of a 3-amino group and the construction of a C-6α-(2-oxo-propyl) group stereoselectively was the challenging task towards the synthesis of designed hapten derivatives. The group has tackled the synthetic hurdle by adopting convergent synthesis approach and validating the stereochemistry by single X ray crystallography.

Furthermore, in vivo Immunological studies of all three new synthetic haptens reveals that one derivative DiAmHap (3) is chemically more stable and better candidate for a heroin vaccine than 6-PrOxyHap (1) and DiPrOxyHap (2). This work is a very positive step towards the development of vaccines for heroin abuse.
