New Drugs in Cancer Chemotherapy

The Analog Potential in Cancer Chemotherapy in the United States and Japan S. K. Carter Northern California Cancer Program, 1801 Page Mill Road, Building B, Suite 200, USA - Palo Alto, CA 94304 The bilateral collaborative program in cancer research between Japan and the United States is one of the oldest programs of this type. It is sponsored in the United States by the National Cancer Institute [1], while in Japan the sponsoring organization is the Japan Society for the Promotion of Science. Annual symposia concerning treatment have been held and in recent years they have been published [2, 3]. Drug development in both Japan and the United States has evolved over the years to an increasing emphasis on second generation compounds. This has come about as a result of the initial successes of chemotherapy development. Many active structures have been uncovered and the armamentarium of the medical and pediatric oncologist has grown dramatically. The uncovering of an active structure provides an opportunity for analog synthesis and attempts at elucidating structure-activity relationships. It is hoped that the therapeutic index of active structures can be improved so as to achieve superior clinical results.
