Processes and Methods (incl. Screening)

Cholestatic liver diseases are a heterogeneous group of disorders resulting from genetic, metabolic and congenital defects, as well as DILI (drug-induced liver injury, a leading cause of attrition during drug development).

Current diagnostic techniques for DILI and cholestasis are based on the detection of serum markers and imaging methods such as computer tomography. However, these have a low resolution and only provide a limited understanding of the underlying disease etiology. Therapeutic ...

Fusion Tags Comprising Ubiquitin-like Modifiers and Corresponding Proteases For Protein Purification From Selected Eukaryotic Expression Hosts

The CRISPR-Cas system is a powerful tool for site-specific genome editing. It allows for the inactivation or substitution of entire genes. However, most hereditary diseases in humans are caused by single point mutations, the correction of which requires only subtle changes to the DNA. Recently, base editors (BEs) were developed that allow the introduction of selective nucleotide substitutions. A Cas9 enzyme is fused to a nucleobase deaminase catalysing C-to-T mutations (by C-to-U deamination) ...

The LITESEC-T3SS (Light-induced translocation of effectors through sequestration of endogenous components of the T3SS) system represents a novel, fast, specific, and reversible method to control protein secretion into eukaryotic cells, enabling various medicinal and biotechnological applications, such as targeted drug delivery for tumor therapy.

We offer a new family of cationic ligands, namely N-alkyl/aryl pyridiniophosphines. The ligands can be synthesized through a short, scalable, and highly modular route.

Evaluation of their electronic properties evidenced weak σ-donor and quite strong π-acceptor character when used as ancillary ligands.

Extremely sensitive, reliable and fast novel KDAC assay, which can be performed in a continuous format. This novel KDAC assay is based on Firefly luciferase harboring an acetylation on an essential active site lysine, incorporated by genetic code expansion. We furthermore offer a bacterial selection system for KDACs, which uses a reporter enzyme inactivated by lysine modifications at an essential active site residue, thereby linking deacetylase activity to a selectable output.

Scientists in the group of Atmospheric Chemistry at the Max Planck Institute for Chemistry in Mainz have developed a novel thiosulfate based ozone scrubber to ensure accurate measurements of trace analytes. It is known from the literature that commercial potassium iodide (KI) containing ozone scrubbers can cause errors in the measurement of carbonyl compounds such as aldehydes and ketones due to byproducts formed from the oxidation of KI. Commercial ozone scrubbers based on sodium thiosulfate ...

The ability of hypervalent iodine compounds to act as electrophilic group-transfer reagents has been extensively exploited during the last several years in a variety of synthetically useful transformations
like cyanations and alkynylations. Now it was found, that novel imidazolium sulfuranes, which are isolobal to I(III) species and also depict the key threecenter four-electron bond motive, can be used as an alternative platform for the development of new electrophilic group-transfer reagents.

Imidazolium ...
