Argyrin a reveals a critical role for the tumor suppressor protein p27kip1 in mediating antitumor activities in response to proteasome inhibition.

TL;DR: This work identifies argyrin A, a cyclical peptide derived from the myxobacterium Archangium gephyra, as a potent antitumoral drug and finds that the biological effects of proteasome inhibition per se depend on the expression of p27(kip1).

Design of chemical libraries with potentially bioactive molecules applying a maximum common substructure concept
Michael Lisurek,Bernd Rupp,Jörg D. Wichard,Martin Neuenschwander,Jens Peter von Kries,Ronald Frank,Jörg Rademann,Jörg Rademann,Ronald Kühne +8 more
TL;DR: Diversity and chemical space coverage of the collection indicate that it is highly diverse and well-placed in the chemical space spanned by bioactive compounds, and secondary assay-validated hits presented in this study show the practical relevance of the library design strategy.
Hepatitis C virus complete life cycle screen for identification of small molecules with pro- or antiviral activity.
Juliane Gentzsch,Bettina Hinkelmann,Lars Kaderali,Herbert Irschik,Rolf Jansen,Florenz Sasse,Ronald Frank,Thomas Pietschmann +7 more
TL;DR: A novel dual reporter gene assay of the complete HCV life cycle was developed and a number of molecules that specifically inhibit HCV cell entry, or primarily virus assembly and release, and also identified molecules that increase viral propagation were identified.

TL;DR: The final EU‐OPENSCREEN library, assembled by merging five independent selections of 40K compounds from various expert groups, represents an excellent example of a Europe‐wide collaborative effort toward the common objective of building best‐in‐class European open screening platforms.

TL;DR: In the quest for new targets for antitumor therapy, the proteasome and its inhibitors have been the focus of academic and industrial research and data already support the high potential of argyrin A as a potential drug candidate, but detailed structure–activity relationship studies, and a molecular understanding of its mode-of-action are a prerequisite for the further optimization of its medicinal potential.
