Progress in Drug Research / Fortschritte der Arzneimittelforschung / Progres des recherches pharmaceutiques

Volume 37 of 'Progress in Drug Research' contains seven articles and the various indexes which facilitate its use and establish the connection with the previous volumes. While all articles deal with some of the topical aspects of drug research, the contribution by Al- fred Burger on 'Isosterism and bioisosterism in drug design' is of great value to those researchers who are engaged in drug design and wish to include isosteric considerations in establishing a work- ing hypothesis. The remaining six reviews provide an overview of the work in- volved in the search for new and better medicines. All these articles contain surveys of the latest findings in the respective domain. In the 31 years this series has existed, the Editor has enjoyed the help and advise of many colleagues. Readers, the authors of the in- dividual reviews and, last but 'not least, the reviewers have all con- tributed greatly to the success of PDR. Although many comments received have been favorable, it is nevertheless also necessary to an- alyze and to reconsider the current position and the direction of such a series.
