In search of safe and effective anti-Alzheimer disease agents a series of gallocyanine dyes have been synthesized and evaluated for their ability to inhibit LRPs/DKK1 interactions. Modulation of the interactions between LRPS and DKK1, regulate Wnt signaling pathway and affect Tau phosphorylation. The current efforts resulted in the identification of potent DKK1 inhibitors which are able to inhibit prostaglandin J2-induced tau phosphorylation at serine 396.

We present an easy test for rapid visualization of viral DNA assemblies in infected cell cytoplasm. We selected the best stains for nuclear staining: Nile blue A, Bismarck brown, gallocyanin chrome alum, methyl green pyronin and azure II. None of the staining techniques is fluorescent, which facilitates their use in everyday experiments.

A novel high-content imaging-based technique for measuring binding of Dickkopf-1 to low-density lipoprotein receptor-related protein 6.

Introduction: Dickkopf-related protein 1 (Dkk1) is a secreted protein ligand of low-density lipoprotein receptor-related protein 6 (LRP6), which antagonises canonical Wnt signalling. Elevated Dkk1 levels have been linked to Alzheimer's disease (AD), with protein blockade protective in pre-clinical AD models, suggesting inhibitors of Dkk1-LRP6 binding may have therapeutic utility against AD. Cell-based Dkk1-LRP6 assays reported in the literature use either modified Dkk1 protein and/or do not possess suitable throughput for drug screening.

Design and synthesis of gallocyanine inhibitors of DKK1/LRP6 interactions for treatment of Alzheimer's disease.

Based on NCI8642, a series of gallocyanine derivatives was synthesized with modifications of the substituent groups in position 1, 2 and 4 of the phenoxazinone scaffold. The effectiveness of gallocyanines to inhibit DKK1/LRP6 interactions and Tau phosphorylation induced by prostaglandin J2 and DKK1 was elucidated by both experimental data and molecular docking simulations. Bis-alkylated with flexible alkyl ester groups on C1 and bis-benzyl gallocyanines provided the most active inhibitors, while amino derivatives on C2 of NCI8642 that have alkoxy or benzyloxy substituents on C4, were less active.

Developing a functional blood substitute as an alternative to donated blood for clinical use is believed to relieve present and future blood shortages, and to reduce the risks of infection and blood type mismatching. Hemoglobin vesicle (HbV) encapsulates a purified and concentrated human-derived Hb solution in a phospholipid vesicle (liposome). The in vivo safety and efficacy of HbV as a transfusion alternative have been clarified.
