Dataset: A Fluorescent Styrylquinoline with Combined Therapeutic and Diagnostic Activities against Alzheimer's and Prion Diseases
[show abstract] [hide abstract]
ABSTRACT: E)-6-Methyl-4′-amino-2-styrylquinoline (3) is a small molecule with the proper features to potentially diagnose, deliver therapy and monitor response to therapy in protein misfolding diseases. These features include compound fluorescent emission in the NIR region and its ability to interact with both Aβ and prion fibrils, staining them with high selectivity. Styrylquinoline 3 also inhibits Aβ self-aggregation in vitro and prion replication in the submicromolar range in a cellular context. Furthermore, it is not toxic and is able to cross the blood brain barrier in vitro (PAMPA test). -

Article: Discovery of a class of diketopiperazines as antiprion compounds.
[show abstract] [hide abstract]
ABSTRACT: Prion diseases are fatal neurodegenerative and infectious disorders for which effective pharmacological tools are not yet available. This unmet challenge and the recently proposed interplay between prion diseases and Alzheimer's have led to a more urgent demand for new antiprion agents. Herein, we report the identification of a novel bifunctional diketopiperazine (DKP) derivative 1 d, which exhibits activity in the low micromolar range against prion replication in ScGT1 cells, while showing low cytotoxicity. Supported by properly addressed molecular modeling studies, we hypothesized that a planar conformation is the major determinant for activity in this class of compounds. Moreover, studies aimed at assessing the mechanism-of-action at the molecular level showed that 1 d might interact directly with recombinant prion protein (recPrP) to prevent its conversion to the pathogenic misfolded prion protein (PrP(Sc))-like form. This investigation suggests that DKP based antiprion compounds can serve as a promising lead scaffold in developing new drugs to combat prion diseases.ChemMedChem 08/2010; 5(8):1324-34. · 3.15 Impact Factor -
