Histamine chemical structure
WebbHistamine was known as a chemical before its presence in biological systems was confirmed. In 1907 Windaus and Vogt described the synthesis of 2-(imidazole-4-yl)ethylamine; much later this compound received the name histamine (Greek histos , ‘tissue’), because of the relatively high concentrations found in tissues.

Black's first idea was to alter the ring by tacking on chemical groups. Although no antagonists were found, it did produce an agonist called 4-methylhistamine, which stimulated acid secretion without any of the other histamine responses.
