Resolving Agent

The invention is directed to novel aminomethyl-pyrroloquinazoline compounds and pharmaceutical compositions thereof which are useful thrombin receptor or PAR-1 antagonists, methods for production thereof and methods for treating thrombin or PAR-1 mediated disorders.

D P T L-Tartaric acid may be most immediately recognizable to wine drinkers as the source of "wine diamonds," the small potassium bitartrate crystals that sometimes form spontaneously on the cork.

DPTL are harmless, despite sometimes being mistaken for broken glass, and are prevented in many wines through cold stabilization. The tartrates that remain on the inside of aging barrels were at one time a major industrial source of potassium bitartrate.

When cream of tartar is added to water, a suspension results which serves to clean copper coins very well. This is due to the fact that the tartrate solution can dissolve the layer of copper(II) oxide present on the surface of the coin. The resulting Copper(II)-tartrate complex that results is easily soluble in water.

D.P.L.Tartaric acid is a muscle toxin, which works by inhibiting the production of malic acid, and in high doses causes paralysis and death.[citation needed] The minimum recorded fatal dose for a human is about 7.5 grams/kg.[citation needed] Given this figure, it would take over 500g to kill a person weighing 70kg.
