Over the last decades distinct members of the G Protein-Coupled Receptor (GPCR) family emerged as prominent drug targets within pharmaceutical research, since approximately 60 % of marketed prescription drugs act by selectively addressing representatives of that class of transmembrane signal transduction systems. It is noteworthy that the majority of(More)
Structurally guided design approaches to low-molecular-weight platelet aggregation antagonists addressing the platelet-associated heterodimeric cell surface receptor gpIIb/IIIa rely on comparative studies of an ensemble of conformationally and biologically characterized compounds, since no high-resolution structure of the receptor system is available. We(More)
Integrins play a major role in cell-cell and cell-matrix interactions. The majority of the different types of integrins recognize the tripeptide sequence arginine-glycine-aspartic acid (RGD). To explore the spatial requirements of the pharmacophore for receptor selectivity and high activity, a new procedure, ‘spatial screening’, was used. The procedure is(More)
The ORLI (opioid receptor like 1)- receptor is a member of the family of rhodopsin-like G protein-coupled receptors (GPCR) and represents an interesting new therapeutical target since it is involved in a variety of biomedical important processes, such as anxiety, nociception, feeding, and memory. In order to shed light on the molecular basis of the(More)
Twenty-five natural products, mainly halogenated furanones, isolated from the temperate red algae Delisea pulchra were investigated for their cytotoxic, antimicrobial, and antiplasmodial effects, their inhibition of the activity of the enzymes HIV-1-RT (HIV-1-reverse transcriptase), PKC (protein kinase C), and TK (tyrosine kinase), and their inhibition of(More)
The seco-prezizaane-type sesquiterpenes pseudoanisatin and parviflorolide from Illicium are noncompetitive antagonists at housefly (Musca domestica) gamma-aminobutyric acid (GABA) receptors. They show selectivity toward the insect receptor and thus represent new leads toward selective insecticides. Based on the binding data for 13 seco-prezizaane terpenoids(More)
The mechanism of the energy-converting NADH (beta-nicotinamide adenine dinucleotide, reduced form):ubiquinone oxidoreductase, which is also called respiratory complex I, is largely unknown due to lack of a high-resolution structure and the most complicated construction of the enzyme. Electron transport is carried out by one flavin mononucleotide (FMN) and(More)
