Synthesis of ganglioside and lysoganglioside lipoforms as internal standards for MS quantification
(2015-01-08)
The goal of this work was to establish methods for the synthesis of modified gangliosides that are suitable as internal standards for mass spectrometry. Quantification of gangliosides is usually achieved by staining after ...
Biosynthesis of soluble capsule precursors in Staphylococcus aureus
(2016-11-28)
Most invasive pathogens produce polysaccharide capsules, which play an essential role in conferring protection against host immune defense. In the case of Staphylococcus aureus, most clinical isolates are encapsulated, and ......
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 ...
Click-SELEX: A versatile approach towards nucleobase-modified aptamers
(2016-11-28)
Aptamers are short nucleic acids that can be selected to bind specifically and with high affinity to a variety of targets, including small organic molecules and proteins. However, for a multitude of targets, traditional ...
Oxytocin – the prosocial molecule?: Intranasal oxytocin effects on social approach behavior, social cognition, volitional and emotional ambivalence in healthy human beings
(2015-10-30)
Oxytocin (OXT) is a highly conserved neuropeptide, regarding both its chemical structure and its functionality. It has been traced back at least 700 million years. OXT’s fundamental role lies in reproduction and parenting ...
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.

Identification, optimization and characterization of pharmacological tools for the cannabinoidactivated orphan G protein-coupled receptor GPR18 and related receptors
(2017-12-21)
Cannabinoid receptors comprise two classical subtypes, CB1 and CB2, which belong to the large family of G protein-coupled receptors (GPCRs). They are the major targets of cannabinoids such as ......
Purines and 9-deazapurines as Modulators of Multidrug Resistance-associated Protein 1 (MRP1/ABCC1)-mediated Transport
(2017-11-14)
Expression of ABC-transport proteins is a major obstacle in cancer chemotherapy. Especially MRP1, P-gp and BCRP are expressed in different malignancies like lung cancer, colon carcinomas, leukemias, bladder cancer, myeloma, ...
Influence of the Conformation of Conotoxins on their Bioactivity
(2017-12-14)
In the last decade peptides filled the gap between small molecule drugs and biologics as therapeutics. A rich source of such peptides represents the venom of different animals evolved over millions of years. Conotoxins are ...
Synthese und Untersuchung neuer ABCG2 Inhibitoren
(2017-03-29)
Aufgrund dessen, dass die Überexpression von ABCG2 eine Rolle bei der Entstehung der Multidrug Resistance von Krebszellen spielt wurde die Entwicklung potenter und selektiver ABCG2 Inhibitoren immer wichtiger. Ziel dieser ...
