    摘要： A process for the preparation of butane triols is provided. In the process, a malic acid diester is reduced with sodium borohydride in the presence of an ether and an alcohol. Preferably, the malic acid diester is an ethyl or methyl ester, the ether is tetrahydrofuran or bis(2-methoxyethyl) ether (diglyme), and the alcohol comprises ethanol. Advantageously, the reaction is carried out at ambient temperature.

    摘要： The present invention relates to the discovery, identification and characterization of toxic agents which are lethal to pathogens and methods for targeting such toxic agents to a pathogen or pathogen infected cells in order to treat and/or eradicate the infection. In particular, the present invention relates to toxic agents which target bacteria at different stages of the bacterial life cycle, which are delivered alone or in combination to bacteria or bacteria-infected cells. The invention relates to toxic agents which are lethal to diseased cells and methods for targeting such toxic agents to a diseased cell in order to treat and/or eradicate the disease. The present invention relates to promoter elements which are pathogen-specific or tissue-specific and the use of such promoter elements to achieve pathogen-specific or tissue-specific expression of the toxic agent(s) and/or ribozyme(s) of the present invention. Specifically, the invention relates to the delivery of one or more toxic gene products, antisense RNAs, or ribozymes, or combination thereof. The invention provides a novel system by which multiple pathogenic targets may be simultaneously targeted to cause the death of a pathogen, or cell infected with a pathogen. Further, the invention has important implications in the eradication of drug-resistant bacterium and bacterial pathogens. The invention provides a novel system by which multiple targets may be simultaneously targeted to cause the death of a diseased cell. The invention also has important implications in the eradication of drug-resistant pathogens and drug-resistant diseased cells (such as cancer cells).

    摘要： Substituted naphthalenyloxy- or naphthalenylthiooxyamides of trans-1,2-diaminocyclohexanes possess selective kappa opioid receptor site binding activity and are thus useful as analgesic or diuretic agents. Methods of preparing the compounds, pharmaceutical compositions, and a method for their use as analgesic agents are also disclosed.

    摘要： Benzamides of the formula (I): ##STR1## in which Ar is optionally substituted aryl; X is O, S or NH and R is optionally substituted alkyl or alkenyl when X is O or S, or is optionally substituted alkanoyl when X is NH, are prepared by(a) reacting a compound of the formula (II):ArCONHCH.sub.2 CN (II) with a brominating agent in a solvent which is substantially chemically inert to the reactants and in which compound (II) is soluble, to form a compound of the formula (III): ##STR2## and (b) reacting the compound (III) with a compound RXH.Preferably, bromination is carried out rapidly in dried ethyl acetate.The process avoids hydration of the CN group of the compound (III) to a carbamoyl group obviating a subsequent dehydration step later.The intermediate compound (III) is novel.The substituted benzamides are useful as herbicides and fungicides.
