Chemical element "Sb" (stibium) for antimony. Chemical symbols are understood internationally when element names might require translation. There have sometimes been differences in the past. For example, Germans in the past have used "J" (for the alternate name Jod) for iodine, but now use "I" and "Iod". The first letter of a chemical symbol is always capitalized, as in the preceding examples, and the subsequent letters, if any, are always lower case (small letters). Thus, the symbols for californium and einsteinium are Cf and Es. There are also symbols in chemical equations for groups of chemical elements, for example in comparative formulas.
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
