Beginning with BCNU in the early 1960s, a total of six nitrosourea compounds have been actively studied in the United States. Two of these drugs, BCNU and CCNU, have reached commercial application. Additional nitrosourea compounds have been placed into clinical study through- out the world in places such as Japan, France, and the Soviet Union. As a class, the nitrosoureas are actively used in a range of solid tumors and the malignant lymphomas. Their continuity in central nervous system neoplasms is particularly noteworthy. Both the preclinical and clinical status of these agents are reviewed. The literature and data on these compounds are so vast that this volume can touch only on some areas in broad overview. It is hoped that both practicing on- cologists and scientists working in drug development will find the book valuable. xix Nitrosoureas Chapter 1 THE DEVELOPMENT OF THE NITROSOUREAS: A STUDY IN CONGENER SYNTHESIS John A.

N-NITROSO FUNCTION In 1955 the United States government launched a national cooperative cancer drug research program under the auspices of the National Cancer Institute (NCI). It began with the screening in animal tumor systems of chemical compounds that might show activity against human cancer (Endicott, 1965). Four years later N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), a compound marketed by the Aldrich Chemical Company for the preparation of diazomethane used by organic chemists for synthetic work, was tested in the laboratories of the Wisconsin Alumni Research Foundation, one of the NCI screening contractors, and found to have significant activity against leukemia LI210, although it was inactive against sarcoma 180 and adenocarcinoma 755, the other two tumors used in the primary screen at that time. In later, confirmatory tests at Hazleton Laboratories and Southern Research Institute, MNNG barely qualified as an LI210 active (Leiter and Schneiderman, 1959). Nevertheless, these findings stimulated the author to submit N- methyl-N-nitrosourea, another, less stable precursor of diazomethane, to the primary screen, with negative results in all the preliminary tests. Since the dose selected for the initial LI210 test—based on the prior results in the S 180 and Ca 755 system—proved to be toxic, no further tests were scheduled. Lower doses, tested at the author's request, produced increases in life span of leukemic mice Copyright © 1981 by Academic Press, Inc.
