Abstract
Candida albicansis an opportunistic pathogen prevalent in AIDS patients and oral candidiasis. Azole-based drugs are currently used in the treatment of candidiasis. Histidine-rich peptides (histatins), are the natural inhibitors of candida species present in human salivary secretions. Sequence comparison of histatins revealed the common motif –KRKFHE– in active peptide fragments. Molecular modeling analysis showed structural similarity between this segment of histatins and azole-based drugs. The helical conformation adopted by histatin-5 may be stabilized by two side chain–side chain interactions (Phe . His and Arg . Glu). Based on sequence comparison of histatin peptides and molecular modeling, a synthetic 10-residue peptide derived from histatin-5 was helical and possessed significant anti candida activity. This peptide may be used as a template to develop histatin-based drugs for treating oral candidiasis.
