MEQUON, Wis., Nov. 28, 2012 /PRNewswire/ -- ENDECE Neural, LLC (www.EndeceNeural.com) announced today that Dr. Steven Nye, Vice President of Discovery, will be presenting at the 2013 Keystone Symposia on Multiple Sclerosis to be held in January, in Big Sky, Montana, USA.
Dr. Nye's presentation, "Estrogen analogs dramatically up-regulate intracellular signaling pathways for remyelination (1)," will review the mechanism behind the novel ENDECE Neural compounds that induce remyelination in rodent animal models of Multiple Sclerosis (MS).
"Unlike current MS therapeutics, which target immune response and inflammation to slow relapses, ENDECE Neural is developing the first drug compounds to induce remyelination of demyelinated axons, and potentially reverse disease progression," states Dr. Nye.
Estrogen analogs dramatically up-regulate intracellular signaling pathways for remyelination.
A new series of nuclear receptor ligands was synthesized for treating multiple sclerosis and other neurodegenerative disorders. The ligands are analogs of 17beta-estradiol (E2) that bind to the estrogen receptors (ERs) and induce distinct intracellular responses which can determine cell fate. Based on molecular modeling studies, modifications to the core structure of E2 were made with different C-6 alkoxyalkyl moieties and/or substitution of the C-18 methyl group. The E2 alterations caused pronounced changes in subtype selectivity for ER-alpha or ER-beta, along with varying degrees of ER dimerization and ER activation. Microarray studies revealed that several of the E2 analogs cause a dramatic up-regulation of genes in signaling pathways related to OPC differentiation and myelin sheath production. While all three E2 analogs are ER agonists, NDC-1308 was the most potent at causing mouse OPC differentiation concomitant with myelin basic protein expression in vitro. The findings presented here relate the structure of the E2 analogs to biological function. We conclude that cellular responses for neuronal repair/remyelination may be controlled to some extent by making key alterations to the core structure of endogenous ER ligands.
