AB In the past 10 years there has been a major expansion in the development
of antifungal drugs, but there are still weaknesses in the range and
scope of current antifungal chemotherapy. New developments have included
the modification of existing drug molecules to eliminate toxicity and
improve activity, for instance, the development of the lipid
formulations of the polyene antifungal agent amphotericin B. Three
different amphotericin B derivatives, a unilamellar liposome (AmBisome),
a colloidal dispersion (ABCD--Amphocil), and a lipid complex (ABLC) are
undergoing evaluation. New triazoles with broad-spectrum antifungal
activity, such as saperconazole, are also being assessed. The
development of groups of drugs with novel modes of action such as cell
wall biosynthesis inhibitors has been slower, although a number of
molecules with activity against key enzymes, including chitin or glucan
synthase, have been found. The morpholine antifungal amorolfine, a
sterol biosynthesis inhibitor, has been developed for the topical
treatment of fungal nail infections. The assessment of these drugs is a
major challenge because it will be necessary to show that they have some
advantage over existing compounds in efficacy, speed of action, or lack
of toxicity.
