These years display the times at which discoveries were made with the compound Adenosine. They're important, because at these times, scientists and doctors were just seeing what could be done with this compound. It is essentially a timeline of the first discoveries of adenosine's uses, right up to the two forms of medicine containing adenosine that have been put out on the market. Only the major discoveries are listed, as there are tons of new uses being discovered for this compound even right now. Listing them all would be quite an exhausting process. History such as the discoverer and the information of discovery is not available for this compound, because it is used in the biological field of chemistry much more than the chemical field. Information that is unnecessary for doctors or biologists simply isn't listed, so one can't find the information on the compound's history.
