[EN] In its many embodiments, the present invention provides -substituted pyridazinone compounds as glucan synthase inhibitors, methods of preparing such compounds, pharmaceutical including one or more of such compounds, methods of preparing pharmaceutical formulations including one or more such compounds or one or more such compounds along with other antifungal agents, and methods of treatment, prevention, inhibition, or amelioration of one or more fungal infections associated with glucan synthase using such compounds or pharmaceutical compositions. [FR] L'invention concerne des composés de pyridazinone substitués en tant qu'inhibiteurs de synthase de glucane ; des procédés de préparation de tels composés, des produits pharmaceutiques comprenant un ou plusieurs de ces composés ; des procédés de préparation de formulations pharmaceutiques comprenant un ou plusieurs de ces composés seuls ou avec d'autres agents antifongiques ; et des procédés de traitement, de prévention, d'inhibition, ou d'amélioration d'une ou de plusieurs infections fongiques associées à une synthase de glucane utilisant de tels composés ou compositions pharmaceutiques.
Enantioselective inclusion of (R)-phenylglycyl-(R)-phenylglycine with benzyl methyl sulfoxides
(RR-1), recognized p-halobenzyl methylsulfoxides with high R-enantioselectivity (86–99% ee) to form inclusion compounds. The single-crystal X-ray analyses showed that RR-1 molecules are arranged in parallel and zigzags via hydrogen bonding to construct a pleated sheet. The guest molecules that form hydrogen bond with +NH3 of RR-1 are accommodated in the channel cavity between the layers. In contrast to
