reaction has become an important tool for the synthesis of new compounds. Mannich bases can be either directly employed or used as intermediates. In this work, the one‐carbon unit transfer reaction of tetrahydrofolatecoenzyme was initiated. 1,3‐Dimethylimidazolidine as a new tetrahydrofolatecoenzymemodel at formaldehyde oxidation level was used to react with ketone having active hydrogen atoms and amine

The present application provides methods for preparing soluble lipidated ligand agents comprising a ligand entity and a lipid entity, and in some embodiments, provides relevant parameters of each of these components, thereby enabling appropriate selection of components to assemble active agents for any given target of interest.
Hydroxylated nebivolol metabolites increase NO release from human endothelial cell preparations in a concentration dependent fashion following acute administration. In addition, hydroxylated nebivolol metabolites, including but not limited to 4-hydroxy-6,6′difluoro-, 4-hydroxy-5-phenol-6,6′difluoro-, and 4-hydroxy-8-pheno-6,6′difluoro-, have the ability to increase the capacity for NO release in human endothelial cells following chronic administration. This invention provides hydroxylated nebivolol metabolites and compositions comprising nebivolol and/or at least one hydroxylated metabolite of nebivolol and/or at least one additional compound used to treat cardiovascular diseases or a pharmaceutically acceptable salt thereof. In addition, this invention provides methods of treating and/or preventing vascular diseases by administering at least one hydroxylated metabolite of nebivolol that is capable of releasing a therapeutically effective amount of nitric oxide to a targeted site affected by the vascular disease. Also, this invention is directed to the treatment and/or prevention of migraine headaches administering at least one hydroxylated metabolite of nebivolol. This invention may also be used in conjunction with or as a single treatment of metabolic syndrome disorders.

The present invention relates to nitric oxide releasing prodrugs of known drugs or therapeutic agents which are represented herein as compounds of formula (I) wherein the drugs or therapeutic agents contain one or more functional groups independently selected from a carboxylic acid, an amino, a hydroxyl and a sulfhydryl group. The invention also relates to processes for the preparation of the nitric oxide releasing prodrugs (the compounds of formula (I)), to pharmaceutical compositions containing them and to methods of using the prodrugs.
E1cb mechanism is the overwhelming process in the reaction of bases and ozonides. As a quenching agent in the ozonolysis of a variety of alkenes, the reactions involving triethylamine often gave better yields and proceeded faster than those involving methyl sulfide. On the other hand, in the presence of 4 Å molecular sieves, the secondary amines reacted with mono- and 1,1-di-substituted ozonides to afford
