Chelation as a strategy with the potential to overcome multidrug resistance in cancer
(2016-09-02)
According to the World Health Organisation cancer is the second leading cause of death in industrialized countries. In many cases treatment fails due to the development of resistance against multiple (structurally and ...
The allosteric core region of the M2 muscarinic acetylcholine receptor: role for ligand selectivity and action
(2015-09-23)
Muscarinic acetylcholine receptors (mAChRs) are seven transmembrane domain-spanning proteins belonging to the family A of G protein-coupled receptors (GPCRs). In addition to the orthosteric binding site (i.e. the site where ...
Proteomische Funktionsanalyse humanbiologischer Systeme mittels chemisch modifizierter Proteine
(2016-04-18)
Das humane Proteom unterliegt gegenüber dem eher statischen Genom einem kontinuierlichen Auf- und Abbau. Diese Dynamik zeigt sich durch ein mehrschichtiges Muster an Protein-Protein Interaktionen.
Im ersten Teil ...

Natural product chemistry and biosynthetic studies of secondary metabolites from the marine-derived fungus Stachylidium sp.
(2016-03-22)
The fungal kingdom has made considerable contributions to the production of peptide secondary metabolites, many of them with therapeutic potential, e.g. the immunosuppressant cyclosporine and the antifungal echinocandins. ...
The orphan G protein-coupled receptor GPR17: its pharmacology and function in recombinant and primary cell expression systems
(2017-04-26)
The reconstitution of myelin sheaths, so called remyelination, represents an innovative therapeutic goal in multiple sclerosis (MS), the most common inflammatory-demyelinating disease of the central nervous system (CNS). ...
Analysis of the natural product biosynthesis in gliding bacteria using in vitro assays
(2017-01-10)
Natural products are most important in drug discovery and therapy, e.g. more than 80% of antibiotics are derived from microorganisms. Antimicrobial resistance is a global threat and thus an urgent need for new antimicrobial ...
The role of guanine nucleotide exchange factors (GEFs) in EGF-receptor signalling: Screening for a small molecule inhibitor of the Rin1-mediated Rab5 activation
(2018-06-04)
The small GTPase Rab5 is a key regulator of early endosomal trafficking. It functions as a molecular switch that can be activated by guanine nucleotide exchange factors (GEFs) and inactivated via hydrolysis of GTP with the ...
Zebrafish as a Model Organism to Study the In Vivo Role of G-Protein Coupled Receptor 17 in Myelination
(2019-02-26)
The sheathing of axons with myelin by oligodendrocytes constitutes a necessity for sufficient and rapid nerve conduction within the vertebrate central nervous system (CNS). However to date, the complex molecular mechanisms ...
Genome mining of marine bacteria for bioactive metabolites
(2019-02-04)
Marine bacteria have come into the focus for natural product discovery as a consequence of the emergence of antibiotic resistance. This was additionally boosted by the limitations encountered in drug developments from ...
Bioinformatische und in-vitro-Analyse der frs-Biosynthesegencluster von Cand. Burkholderia crenata und Chromobacterium vaccinii
(2019-07-03)
FR900359 (FR) ist ein selektiver Gq-Proteininhibitor, der ursprünglich aus der Pflanze Ardisia crenata isoliert wurde. G-Proteine spielen eine zentrale Rolle in der Signalübertragung von G-Protein ......
