History of Chemistry in the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).

The origins of the Laboratory of Bioorganic Chemistry, NIDDK, NIH can be traced to events that occurred in the early 20th century. From its beginning to the present, as the laboratory evolved through several organizational changes, many important historical contributions to organic chemistry and biochemistry were made. For example, its early precursor, the Division of Chemistry of the Hygienic Laboratory, was assigned the responsibility of safeguarding public health by analyzing environmental and other chemical risks. This review will trace important developments from the early twentieth century to the present. The topics covered in this review include a historical synopsis, early work on receptors, carbohydrates, heterocycles and nucleotides, with specific emphasis on frog skin alkaloids, the NIH shift (a transfer of an aromatic hydrogen atom to a neighboring ring position during ring hydroxylation, important in the biochemical processing of aromatic substrates), the methionine-specific cleavage of proteins using cyanogen bromide (used commercially and in peptide research) as well as other fundamental contributions. Ongoing research in medicinal chemistry, natural products, biochemistry, vaccines and pharmacology, some leading to clinical applications, will be discussed.
