WebAbstract. The objective of the glossary is to provide in a single document a consistent terminology and concise definitions of terms covering the various aspects of medicinal chemistry. This was felt necessary with regard to the rapid changes occuring in medicinal chemistry and also by the need to establish international definition standards. WebThe approach of Hansch is the most developed model in this area. Here electronic, hydrophobic, and steric substituent constants are used for a quantitative analysis of the possible ways in which substitution may modulate bio-activity in a congeneric series (quantitative structure-activity relations; q.s.a.r.). hcg tumour marker

WebThe optimization of active substances follows a process that is best characterized by the words of the philosopher Sir Karl Popper: The truth is objective and absolute. But we can never be sure that we have found it. Our knowledge is always an assumed knowledge. Our theories are hypotheses. We test for the truth in that we exclude what is false. WebThe first 3-D QSAR was named Comparative Molecular Field Analysis (CoMFA) by Cramer et al. It examined the steric fields (shape of the molecule) and the electrostatic fields [20] which were correlated by means of partial least squares regression (PLS).
