    Tricyclic pyrone compounds having high oral bioavailability, excellent blood-brain barrier permeability, and low toxicity are presented. Administration of the compounds to Alzheimer's Disease transgenic models resulted in substantially reduced soluble and insoluble Αβ species in the brain without affecting general behavior and motor coordination. Furthermore, in addition to blocking the toxicity and formation of both intraneuronal and extracellular Αβ aggregates, the compounds also increase cellular cholesterol efflux, restore axonal trafficking, and enhance hippocampal synaptic plasticity.

  • Inhibition of Acyl-CoA: Cholesterol Acyltransferase (ACAT), Overexpression of Cholesterol Transporter Gene, and Protection of Amyloid β (Aβ) Oligomers-Induced Neuronal Cell Death by Tricyclic Pyrone Molecules

    A major effort in Alzheimer's disease therapeutic development has targeted A beta and downstream :vents. We have synthesized a small library of tricyclic pyrone compounds. Their protective action in MC65 cells and inhibition of ACAT along with the upregulation of cholesterol transporter gene were investigated. Five active compounds exhibited potencies in the nanomolar ranges. The multiple effects of the compounds on A beta and cellular cholesterol pathways could be potential mechanisms underlying the protective effects in vivo.
  • Synthesis and anti-norovirus activity of pyranobenzopyrone compounds

    During the last decade, noroviruses have gained media attention as the cause of large scale outbreaks of gastroenteritis on cruise ships, dormitories, nursing homes, etc. Although noroviruses do not multiply in food or water, they can cause large outbreaks because approximately 10-100 virions are sufficient to cause illness in a healthy adult. Recently, it was shown that the activity of acyl-coenzyme A:cholesterol acyltransferase-1 (ACAT1) enzyme may be important in norovirus infection. In search of anti-noroviral agents based on the inhibition of ACAT1, we synthesized and evaluated the inhibitory activities of a class of pyranobenzopyrone molecules containing amino, pyridine, substituted quinolines, or 7,8-benzoquinoline nucleus. Three of the sixteen evaluated compounds possess ED50 values in the low micrometer range. 2-Quinolylmethyl derivative 3A and 4-quinolylmethyl derivative 4A showed ED50 values of 3.4 and 2.4 mu M and TD50 values of >200 and 96.4 mu M, respectively. The identified active compounds are suitable for further modification for the development of anti-norovirus agents. (C) 2012 Elsevier Ltd. All rights reserved.
