The decade of the 1990s will see an increasing emphasis on the modulation of chemotherapeutic drug selectivity and in the 'lock and key' approach to new targets to control malignant proliferation. The contents of this volume appropriately reflect these scientific undercurrents. An emerging powerful tool of molecular pharmacology is described by Holcenberg and Wu. Manipulation of genetic expression by modification of messenger RNA is now within our reach, and the basic concepts are suc cinctly reviewed as a primer on future biochemical engineering of new anti cancer molecules. Another concept...

Concepts, Mechanisms, and New Targets for Chemotherapy describes new interconnections between rationally designed and empirically discovered compounds. One route that has not been travelled previously is that of protein kinase C inhibition. This pathway may be exploited to give potent inhibitors, such as the bryostatins, now in clinical trial. A summary is given of the current status of topoisomerase, focusing on recent clinical advances with camptothecin analogs based on connecting empiricism with concepts of drug selectivity.
Modification of existing therapies based on the...
