The author reflects on the article of Doctor Richard Cramer regarding the results from the 22 years since the first publication of the three-dimensional (3D) quantitative structure-activity relationship (QSAR) method. She says that Cramer has shown the consideration of 3D properties of the ligand structures in a two-edged sword. She also notes that Cramer also focuses on the emphasis of Topomer comparative molecular field analysis (CoMFA) on modifications in the structure of the small molecule.
