The present invention relates to a series of novel compounds which have been shown to possess antifungal activity. The invention therefore relates to the new compounds, methods for their preparation, pharmaceutical compositions comprising them and to the compounds for use as a medicament, more in particular antifungal medicament.
[Object]: To provide a compound having a novel structure effective against
Hemophilus influenzae
and erythromycin resistant bacteria (for example, resistant pneumococci and streptococci) as well as against conventional erythromycin sensitive bacteria.
[Solution]: A novel 10a-azalide compound represented by the formula (I), a pharmaceutically acceptable salt thereof or a solvate thereof, or an intermediate for the preparation of the same. The compound of the present invention has superior antibacterial activity against
Hemophilus influenzae
, erythromycin resistant pneumococci and the like, and therefore, the compound can be used as a therapeutic agent of infectious diseases.

From a fungicidal screen, we identified 2-(2-oxo-morpholin-3-yl)-acetamide derivatives as fungicidal agents against Candida species, additionally characterized by antifungal activity against Aspergillus species. However, development of this series was hampered by low plasmatic stability. Introduction of a gem-dimethyl on the 6-position of the morpholin-2-one core led to considerable improvement in plasmatic stability while maintaining in vitro antifungal activity. Further optimization of the series resulted in the discovery of N-(biphenyl-3-ylmethyl)-2-(4-ethyl-6,6-dimethyl-2-oxomorpholin-3-yl)acetamide (87), which, in addition to fungicidal activity against Candida species, shows promising and broad antifungal in vitro activity against various fungi species, such as molds and dermatophytes. In vivo efficacy was also demonstrated in a murine model of systemic Candida albicans infection with a significant fungal load reduction in kidneys.
