Introduction

ByP.N.KourounakisE.A.Rekka

The discovery of drugs and drug molecules has always been the aim of pharmaceutical sciences and, in particular, of medicinal chemistry, which evolved from pharmaceutical chemistry. Half a century ago, pharmacochemistry, the modern expression of pharmaceutical chemistry, as a science whose main interest is the design and development of new pharmacomolecules, was at the beginning of its evolution. Drug design in its broad sense and structure-activity relationship studies are essential and at the heart of medicinal chemistry, and it is the progress and development of this field of research that has made medicinal chemistry the modern and enormously productive science it has become in recent decades [1]. Today, studies on structure-activity relationships and their influence on the design of new drugs have rendered them one of the most useful and thus important activities of pharmacochemistry, a modern component science in the group of pharmaceutical sciences [2].
