Extremely fast and efficient Diels-Alder chemical ligation of furan and maleimide oligonucleotides has been carried out in aqueous buffer. It was possible to ligate three oligonucleotides simultaneously in a controlled manner with the aid of a complementary splint. The templated reactions proceeded within 1 min at room temperature whereas non-templated reactions were slow and incomplete. Rapid and clean methods of DNA ligation such as the one demonstrated here have potential uses in biology and nanotechnology.

Immune checkpoint inhibitor (ICI) therapy is a cornerstone treatment for many cancers, but it can induce severe immunotoxicity, including acute interstitial nephritis (AIN). Currently, kidney biopsy is required to differentiate ICI-AIN from other causes of acute kidney injury (AKI). However, this invasive approach can lead to morbidity, delayed glucocorticoid treatment for patients with AIN, and unnecessarily prolonged suspension of ICI therapy in non-AIN patients.

Peptides and proteins are important functional biomolecules both inside and outside of living organisms. The ability to prepare various types of functionalized peptides and proteins is essential for understanding fundamental biological processes, such as protein folding and post-translational modifications (PTMs), and for developing new therapeutics for many diseases, such as cancers and neurodegenerative diseases. The o-aminoaniline moiety was first proposed for activation to a thioester precursor and used for native chemical ligation to prepare large peptides and proteins.

The technology of native chemical ligation and postligation desulfurization has greatly expanded the scope of modern chemical protein synthesis. Here, we report that ultrasonic energy can trigger robust and clean protein desulfurization, and we developed an ultrasound-induced desulfurization (USID) strategy that is simple to use and generally applicable to peptides and proteins. The USID strategy involves a simple ultrasonic cleaning bath and an easy-to-use and easy-to-remove sonosensitizer, titanium dioxide.

The exploration of ligated metal clusters' chemical space is challenging, partly owing to an insufficiently targeted access to reactive clusters. Now, dynamic mixtures of clusters, defined as living libraries, are obtained through organometallic precursor chemistry. The libraries are populated with interrelated clusters, including transient and highly reactive ones, as well as more accessible but less reactive species.

Studies presenting visible-light-induced desulfurization of peptides containing a cysteine residue have been carried out. This transformation driven by light-emitting-diode-type light proceeds with high efficiency in an aqueous solution at room temperature and involves the use of a catalytic amount of photosensitizer, Rose Bengal. The procedure has been tested on model synthetic peptides, lysozyme C and α-crystallin, and successfully applied to a one-pot native chemical ligation (NCL)-desulfurization protocol.
