“…Recent reviews also have dealt with: adrenergic neurone blocking agents (139), /3-adrenergic blockers (140), inhibition of norepinephrine uptake by drugs (141), agents influencing DOPAmine-/3-hydroxylase (142), catecholamine-like compounds acting at adrenergic receptors (143), and 2-halogenoethylamine adrenergic blockers (144). The related subject of dihydroxyphenylalanine analogues also has been thoroughly covered (145). Discussions of SAR among compounds of this section will be limited to material in some very recent reports.…”

Earlier reviews in this series dealt with some relationships of chemical structure with biological activities (1-3) i the present assignment is restricted essentially to pharmacologically active compounds. As with the earlier re views, the published literature is not covered exhaustively, but some new re ports and observations are included which appeared from about September, 1964 [termination of coverage of last review (1)] to May, 1967. Where useful for purposes of relationship, selected older literature is cited.Over the years attempts have been made to devise general hypotheses pertaining to structure-activity relationships (SAR) and drug mechanisms of action. Recent efforts include variations of receptor occupancy hypotheses (Ariens, Stephenson), rate or kinetic hypotheses (Paton), and more chemi cally descriptive concepts (Belleau and others). In reviewing publications of the past two years that could be considered pertinent to SAR, one is im pressed by the gulf that exists between most synthesizers of new molecules and the developers of general hypotheses. For example, from 310 complete articles published in J. Med. Chern. (1965-66), only six made reference to these hypotheses either as stimuli for the project or as vehicles for cor relating SAR. This might indicate that the hypotheses are sterile or inade quate for either predictive or correlative purposes or that there is little in terest or inclination among most investigators in relating specific observa tions to general hypotheses. Most of these hypothes,t!s have indeed offered little that is of substantive value from a chemical perspective of devising novel molecules of biological interest. However, the efforts are commendable and some of these hypotheses may evolve and develop into theories with use ful correlative and predictive values. As hypotheses become more chemically descriptive, one can anticipate that there will be a greater consideration of such hypotheses by the designers of new, biologically interesting molecules.Their more recent concepts have been summarized by Ariens (4) and Paton (5). Shortcomings of the Ariens and Stephenson receptor occupancy and the Paton rate hypotheses have been analyzed by Belleau (6) as back ground for discussion of his "conformational perturbation" hypothesis.Bloom & Goldman (7) further consider these and modify and extend some of Belleau's views in proposing a "dynamic receptor hypothesis" relevant to catecholamine-adenine mononucleotide interactions in adrenergic mech anisms.
