Chirality: a key parameter in chemical probes

Chiral compounds are vital as chemical probes. Choosing a wrong enantiomer (mirror image) can be disastrous in a medicinal chemistry programme. Here, a male kingfisher emerges from the water with its “active form” above the surface.

P1 Glutamine isosteres in the design of inhibitors of 3C/3CL protease of human viruses of the Pisoniviricetes class

Viral infections are one of the leading causes of acute morbidity in humans and much endeavour has been made by the synthetic community for the development of drugs to treat associated diseases.

Design, synthesis and modelling of photoreactive chemical probes for investigating target engagement of plasmepsin IX and X in Plasmodium falciparum

We report the synthesis and biological profiling of photoreactive chemical probes based on an established plasmepsin X inhibitor scaffold. Maintained antimalarial and recombinant enzyme activity support their use in future chemical proteomic studies.

A cell-permeable probe for the labelling of a bacterial glycosyltransferase and virulence factor

We report a chemical probe for the fluorescent labelling of the bacterial glycosyltransferase LgtC, a known virulence factor in Haemophilus and Neisseria species, and its application with recombinant protein, cell lysates, and intact cells.

Kinetic and inhibition studies on human Jumonji-C (JmjC) domain-containing protein 5

Robust mass spectrometry-based assays are reported which monitor catalysis of the 2-oxoglutarate-dependent oxygenase Jumonji-C domain-containing protein 5 (JMJD5). The assays have been applied to both kinetic and inhibition studies.
