A series of 3-(arylalkyl)-2,4,5-trioxoimidazolidine-1-acids (1) was prepared and tested for aldose reductase (AR) and aldehyde reductase (ALR) inhibitory activities. These compounds showed strong inhibitory activity against AR without significant inhibitory activity for ALR. The ratio of IC50(ALR)/IC50(AR) was > 1000 in some compouds. On the basis of pharmacological tests such as the recovery of reduced motor nerve conduction velocity and toxicological profile, 3-(3-nitrobenzyl)-2,4,5-trioxoimidazolidine-1-acid (NZ-314) was selected as the candidate for clinical development.

The present invention relates to dihydro-cyclopenta-isoquinoline derivatives of formula (I), processes for preparing them, pharmaceutical compositions containing them and their use in treating disorders caused by IgE (such as allergic responses, non-allergic mast cell responses or certain autoimmune responses), and in particular disorders caused by the interaction of IgE with the FcεRI receptor.
Described is a A liquid colloidal pharmaceutical formulation of a type B lantibiotic for infusion or direct injection comprising a type B lantibiotic or a salt thereof, an isotonic aqueous solution comprising a sugar alcohol such as glycerol and/or a saccharide and optionally a buffer, wherein said final formulation for infusion or direct injection is clear of visual particulates.
The present disclosure relates to compounds of formula (II):
pharmaceutical compositions comprising same and use of the compounds and compositions for the treatment of microbial infection, particularly Methicillin-resistant
Staphylococcus aureus
(MRSA) infection.
significance of such pioneering reactions. Due to the markedly polar attributes and insolubility of the resulting products in water, facile separation from the reaction milieu is facilitated through the introduction of water into the reaction mixture. Consequently, this specific ionic liquid methodology provides an uncomplicated and selective avenue for the synthesis of compounds possessing noteworthy
