Accumulation of 3-ketosteroids induced by itraconazole in azole-resistant clinical Candida albicans isolates.

The effects of itraconazole on ergosterol biosynthesis were investigated in a series of 16 matched clinical Candida albicans isolates which had been previously analyzed for mechanisms of resistance to azoles (D. Sanglard, K. Kuchler, F.

Azole antifungals: weak inhibitors of inducible nitric oxide synthase in mouse and human cells.

The effect of three azole antifungals on inducible nitric oxide (iNOS) activity in different mouse and human cells was evaluated. The iNOS activity was determined by L-citrulline and nitrite measurement. In the murine macrophage cell line RAW 264.
