Period 5 element corrosion-resistant tin plating of steel. Because of its low toxicity, tin-plated metal is also used for food packaging, giving the name to tin cans, which are made mostly of steel. Antimony () is a toxic chemical element with the symbol Sb and an atomic number of 51. A lustrous grey metalloid, it is found in nature mainly as the sulfide mineral stibnite (SbS). Antimony compounds have been known since ancient times and were used for cosmetics, metallic antimony was also known but mostly identified as lead. For some time China has been the largest producer of antimony and its compounds,
SB-269970 dopamine release in the ventral tegmental area. Possible therapeutic uses for SB-269970 and other 5-HT antagonists include the treatment of anxiety and depression, and nootropic effects have also been noted in animal studies. SB-269970 SB-269970 is a drug and research chemical developed by GlaxoSmithKline used in scientific studies. It is believed to act as a selective 5-HT receptor antagonist (EC = 1.25 nM) (or possibly inverse agonist). A subsequent study in guinea pig at 10 uM showed that it also blocks the α-adrenergic receptor activity. The significant difference in test concentrations, however, confirms the selectivity of SB-269970 for the 5-HT
