Probably all brain functions are modulated through receptor site activity, including memory and other cognitive processes.
The idea of this new drug is instead of lowering the testosterone it blocks it at the receptor site in the prostate.
The researchers found they could use this effect for sensing by attaching a specific ligand to the acceptor molecule; the new molecular package then gets pulled away from the polymer by the receptor site of a biological or chemical agent, and the polymers luminescence is restored.
Eszopiclone may play a role in causing calcium to flood across the GABA receptor complex by either binding to a receptor site near the complex or by binding to the BZD subunit of the GABA receptor complex.
In contrast, the new imprinting process developed by Zimmerman and his colleagues at the University of Illinois produces just one receptor site per molecule.
If a drug were tailored to occupy this receptor site, it might thwart the disease, he says.
Nature, of course, continually makes use of all these forces for receptor site mediated biological processes.
John Anderson, consultant urologist at Sheffield's Royal Hallamshire Hospital, said yesterday: "Instead of lowering testosterone levels, this new drug blocks it at the receptor site in the prostate.
By acting at both the AMPA and kainate receptor site to competitively block the binding of glutamate, tezampanel and its oral prodrug, NGX426, have the potential to treat a number of diseases and disorders.
After examining a similar receptor site on the enzyme urokinase--an even closer relative of tPA whose structure remains undetermined--the Dallas team inserted on the tPA surface a clump of sugar molecules that "covers the receptor site like an umbrella," preventing the liver cells from attaching, he says.
But too much of either chemical kills certain cells, and past studies have shown quinolinic acid and glutamate bind to the receptor site for a chemical abbreviated NMDA.
