Optically Active Antifungal Azoles. XII. Synthesis and Antifungal Activity of the Water-Soluble Prodrugs of 1-[(1R,2R)-2-(2,4-Difluorophenyl)-2-hydroxy-1-methyl-3-(1H-1,2,4-triazol-1-yl)propyl]-3-[4-(1H-1-tetrazolyl)phenyl]-2-imidazolidinone.
The composition of the present invention comprises a quaternized nitrogen-containing imidazole-1-yl or 1,2,4-triazole-1-yl compound wherein one of the nitrogen atoms constituting the azole ring is quaternized with a group eliminating in vivo and represented by the formula:
wherein R1 represents a hydrocarbon or heterocyclic group which may be substituted, R2 represents a hydrogen atom or a lower alkyl group, and n is 0 or 1, and a saccharide, said compound being capable of being converted into an anti-fungal azole compound upon elimination of said group in vivo. The composition of the present invention is stable and usable particularly as a pharmaceutical preparation for an injection composition.
