Prion-based diseases are incurable transmissible neurodegenerative disorders affecting animals and humans. Here we report the discovery of the in vivo antiprion activity of Guanabenz (GA), an agonist of alpha2-adrenergic receptors routinely used in human medicine as an antihypertensive drug. We...

Progress in molecular biology and translational science, 106, 75-106 (2012-02-22)
The unfolded protein response, also known as endoplasmic reticulum (ER) stress, has been implicated in numerous human diseases, including atherosclerosis, cancer, diabetes, and neurodegenerative disorders. Protein misfolding activates one or more of the three ER transmembrane sensors to initiate a...

Guanabenz is an orally active central alpha 2-adrenoceptor agonist. Its antihypertensive action is thought to result from a decrease in sympathetic outflow from the brain to the peripheral circulatory system as a result of stimulation of central alpha 2-adrenoceptors. In...

Selective and reversible phosphorylation is one of the most common post-translational modifications of proteins. Although kinase inhibitors are popular in drug development programmes, selective pharmacological manipulation of phosphatase activity has been challenging to achieve. We review recent advances in the...
