Most drug discovery efforts for Alzheimer's disease (AD) have focused on prevention or clearance of beta-amyloid (Abeta) fibrils or oligomers, with far less attention to prevention of tau abnormalities that lead to neurofibrillary tangles (NFTs). Much evidence now indicates that Abeta multimers can trigger neurodegenerative changes that involve formation of… (More)
Altiratinib (DCC-2701) was designed based on the rationale of engineering a single therapeutic agent able to address multiple hallmarks of cancer (1). Specifically, altiratinib inhibits not only mechanisms of tumor initiation and progression, but also drug resistance mechanisms in the tumor and microenvironment through balanced inhibition of MET, TIE2… (More)
The dactylocycline antibiotics were found through circular dichroism measurements, NMR spectroscopy and chemical transformations to possess the usual tetracycline family absolute configuration at carbons 4, 4a, 5a and 12a. The absolute stereochemistry about the C-6 carbon, however, was the reverse of that found with previously investigated tetracyclines.
Compounds that interact with microtubules, such as paclitaxel, have been shown to possess protective properties against beta-amyloid (Abeta) induced neurodegeneration associated with Alzheimer's disease. In this work, the novel agent (3R,5S,7as)-(3,5-bis(4-fluorophenyl)tetrahydro-1H-oxazolo[3,4-c]oxazol-7a-yl)methanol was investigated for effectiveness in… (More)
