Physicochemical background of the Hansch-Fujita QSAR

From Hansch-Fujita Analysis to AFMoC: A Road to Structure-Based QSAR.

Since the pioneering effort of Hansch and Fujita, quantitative structure-activity relationships (QSAR) have proved valuable in optimizing lead structures. Enriching classical 3D-QSAR analysis, which exploits the three-dimensional structure of ligands, with structural information of the target has helped to improve the interpretability of the derived models and to increase their predictive power...

QSAR : Hansch Analysis and Related Approaches

In tribute to Corwin Hansch, father of QSAR

In this issue of Journal of Computer-Aided Molecular Design we pay tribute to Corwin Hansch, who died on May 8 at the age of 91. Professor Hansch (Corwin to almost everyone, at his insistence) was a giant in our field, the ‘father’ of QSAR, and the vanguard of rational drug design. Thanks to his long-time colleague and coworker, Cynthia Selassie, also of Pomona College, we are, with sadness, pu...

Rationalization of Physicochemical and Structural Requirement of Some Substituted 5-(Biphenyl-4-ylmethyl)Pyrazole as Angiotensin II Receptor Antagonist: A QSAR Approach

      A series of angiotensin II (A II) receptor antagonist of some substituted 5-(biphenyl-4-ylmethyl) pyrazole were subjected to QSAR analysis using Hansch and Fujita-Ban model, by using combination of thermodynamic, electronic, spatial descriptor and presence or absence of substituent respectively. Several QSAR model were obtained using stepwise regression analysis. Two models from both the ...

the effects of previewing and providing background knowledge on iranian university efl learners’ comprehension of literary and academic texts

abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
