either in the coordinationsphere of the metal (path I) or after dissociation from the metal (path II). Path I yields the Ru-bound zwitterionic form of the hemiaminal protonated at nitrogen, which eliminates H2, forming the amide product. In path II, the free hemiaminal dehydrates, giving an imine, which yields the amine product by hydrogenation with the reduced form of the catalyst generated in the initial
This invention relates to a pharmaceutical comprising as an effective ingredient an arylmethylene urea exemplified by the following formula:
or a pharmaceutically acceptable salt thereof. The arylmethylene urea and the pharmaceutically acceptable salts thereof are useful for therapy or prophylaxis of inflammatory bowel disease and overactive bladder.
The invention encompasses methods of modulating CFTR activity in a subject in need thereof comprising administering an effective amount of a compound of Formula (I). The invention also encompasses methods of treating a condition associated with CFTR activity or condition associated with a dysfunction of proteostasis comprising administering to a subject an effective amount of a compound of Formula (I).
This invention relates to a corrosion inhibited system comprising I An oxygenated fuel and II the reaction products of
(1) an alkenyl or alkyl succinic acid or anhydride or the polymer thereof; and
(2) an amine.
