Protein phosphatases have very recently emerged as important targets for chemical biology and medicinal chemistry research, and new phosphatase inhibitor classes are in high demand. The underlying frameworks of natural products represent the evolutionarily selected fractions of chemical space explored by nature so far and meet the criteria of relevance to(More)
Protein phosphatases have recently emerged as important targets for research in chemical biology and medicinal chemistry, and new classes of phosphatase inhibitors are in high demand. BIOS (biology-oriented synthesis) employs the criteria of relevance to nature and biological prevalidation for the design and synthesis of compound collections. In an(More)
Macrolines constitute a class of natural products that has more than 100 members and displays diverse biological activities. These compounds feature a cycloocta[b]indole scaffold that represents an interesting target structure for biology-oriented synthesis (BIOS). We have presented a solid-phase synthesis of isomerically pure cycloocta[b]indoles by(More)
Computational approaches are frequently used in ligand design. We have developed two complementary techniques , the Protein Structure Similarity Clustering (PSSC) [1] and the Scaffold Tree [2,3]. The PSSC is based on subfold similarity around the binding sites of proteins. Its central hypothesis is that structurally similar binding sites bind structurally(More)
A collection of approximately 11 000 natural-product derived and inspired compounds was screened for potential apoptosis inducers in the human tumour cell lines HepG2 (liver), HeLa (cervix) and MCF-7 (breast) by means of MTT and ATP-luminescence assays, automated cell counting, caspase 3/7 assay as well as by fluorescence activated cell sorting (FACS)(More)
