Group 11 element Group 11 element Group 11, by modern IUPAC numbering, is a group of chemical elements in the periodic table, consisting of copper (Cu), silver (Ag), and gold (Au). Roentgenium (Rg) is also placed in this group in the periodic table, although no chemical experiments have yet been carried out to confirm that it behaves like the heavier homologue to gold. Group 11 is also known as the "coinage metals", due to their former usage. They were most likely the first three elements discovered. Copper, silver, and gold all occur naturally in elemental form. All the elements of the group except
CU-2010 and CU-2020 of free radicals and less lipid peroxidation with the amount of malonaldehyde in the heart tissue being reduced. However, the activation of neutrophils does not seem to be altered. CU-2010 and CU-2020 improve coronary endothelial function similarly to aprotinin. Unlike aprotinin, at high doses, their anti-inflammatory properties allow for the improvement in the recovery of contractility in the left ventricle after ischemic conditions, and increase the protection of the myocardium. Moreover, CU-2010 and CU-2020 do not compromise clot strength, and do not affect the function of vascular smooth muscle. CU-2010 and CU-2020 CU-2010 and CU-2020 are synthetic compounds that act
