title: Correlation analysis of Baker's studies on enzyme inhibition. 1. Guanine deaminase, xanthine oxidase, dihydrofolate reductase, and complement.
abstract: Five correlation equations are presented which relate inhibitory activity of 578 inhibitors of guanine deaminase, xanthine oxidase, dihydrofolate reductase, and complement to their chemical structures. The use of correlation analysis in enzyme studies for drug development is discussed. The importance of indicator variables in such studies is emphasized.
