A series of novel 1, 2, 3, 4-tetrahydroisoquinoline derived azoles has been designed and synthesized as antifungal agents which might function as inhibitors of cytochrome P-450 dependent lanosterol 14α-demethylase. In vitro tests showed that some of these compounds, especially 5b and 6b, effectively inhibit the growth of several strains of yeasts as well as molds.
