The present work deals with the relationship between biological activities of differently substituted phenols and their physico-chemical parameters expressing the influence of hydrophobic, electronic and steric factors. The testing was performed with the fungi Trychophyton gypseum and Trychophyton gypseum var. Kaufman-Wolf and the yeast Candida albicans. Significant relationship between biological activity and pKA values was calculated. The interactions between individual factors as well as the influence of the position of substituents on quantitative structure-activity relationships are discussed.
