标 题:Process for the synthesis of o-substituted oxime compounds
发明人：CHEMPOLIL THOMAS MATHEW
权利人:ALLIED SIGNAL INC
摘要:A novel process for the production of O-substituted oximes is disclosed. The process involves reacting an oxime with an alkali-metal hydroxide optionally in a solvent which forms an azeotrope with water to form a mixture of the alkali metal salt of the oxime and water, removing all or a portion of the water by distilling the mixture azeotropically and reacting the distilled mixture with an alpha halo carboxylic acid.

发明人：UNGER EVAN C; MCCREERY THOMAS; SADEWASSER DAVID
权利人:IMARX PHARMACEUTICAL CORP
摘要:The present invention is directed to a method of increasing nucleic acid synthesis in a cell comprising administering to the cell a therapeutically effective amount of ultrasound for a therapeutically effective time such that said administration of said ultrasound results in said increased nucleic acid synthesis. The nucleic acid sequence may comprise an endogenous sequence or an exogenous sequence.
