    • A 9-O-alkanoyl-3"-O-alkanoyloxymethyl-SF-837 substance is now synthetized, which is a new compound useful in that this new 9-O-alkanoyl-3"-O-alkanoyloxymethyl derivative of the SF-837 substance exhibits an antibacterial activity comparable to that of the parent SF-837 substance but is advantageously free from the unpleasant bitter taste inherent to the SF-837 substance and is hence adapted for oral administration. A process of producing the 9-O-alkanoyl-3"-O-alkanoyloxymethyl-SF-837 substance is also provided, which comprises hydrolysing partially and selectively a 9,2'-di-O-alkanoyl-3"-O-alkanoyloxymethyl-SF-837 substance in an aqueous alkanol or aqueous acetone. The 9,2'-di-O-alkanoyl-3"-O-alkanopyloxymethyl-SF-837 substance may be prepared by reacting a 9,2'-di-alkanoyl- or O-mono-O-alkanoyl-3"-O-thiomethoxymethyl-SF-837 substance with an alkanoic anhydride which is exemplified by acetic anhydride or propionic anhydride in the specification.
    • 现在合成了9-O-烷酰基-3“-O-烷酰氧基甲基-SF-837物质,这是一种新的化合物,有用的是这种新型的9-O-烷酰基-3'-O-烷酰氧基甲基衍生物 -837物质表现出与母体SF-837物质相当的抗菌活性,但有利地没有SF-837物质固有的不愉快的苦味,因此适于口服给药。 还提供了制备9-O-烷酰基-3“-O-烷酰氧基甲基-SF-837物质的方法,其包括部分和选择性地水解9,2'-二-O-烷酰基-3'-O - 烷酰氧基甲基-SF-837物质在链烷醇水溶液或丙酮水溶液中。 9,2'-二-O-烷酰基-3“-O-烷酰氧基甲基-SF-837物质可以通过使9,2'-二烷酰基或O-单-O-烷酰基-3' 具有链烷酸酐的“-O-硫代甲氧基甲基-SF-837”物质,其例示在说明书中的乙酸酐或丙酸酐。

    • New antibacterial 1-oxadethiacephalosporin derivatives of the general formula ##STR1## wherein R is a heterocyclic group or a group --S--Het where Het denotes a heterocyclic group, Y is a hydrogen atom or a methoxy group; x and y are each an integer of 1 to 3 is produced by a process comprising condensing a 1-oxacephem compound of the formula ##STR2## wherein R, Y, y are as defined above; R' is a hydrogen atom or a carboxyl-protecting group; and Z is a halo group, with a sulfur-containing amino acid of the formula ##STR3## wherein x is as defined above, in a solvent and removing, if necessary, the residual protective group from the resultant condensation product. The new 1-oxadethiacephalosporin derivatives and the pharmaceutically acceptable salts and esters thereof exhibit high and broad "in vitro" and "in vivo" antibacterial activity, particularly against .beta.-lactamase-producing strains of gram-negative bacteria.

    • 2-Amino-4-(hydroxy) (methyl)phosphinoylbutyric acid, which earlier nomenclature referred to as 2-amino-4-methylphosphinobutyric acid or its metal salts, or acid-addition salts thereof are used as perennial weeds and brush controlling agents. The L-isomer is twice effective than the racemic acid. The perennial weeds and brush controlling effect may be obtained by foliar application over a prolonged period and may be surprisingly enhanced by using the compound with a herbicide or synergist selected from the group consisting of choline salt of maleic hydrazide, a phenoxy series herbicide, a benzoic acid series herbicide, 2,3,6-trichlorophenylacetic acid or a salt thereof, (3,5,6-trichloro-2-pyridyl)oxyacetic acid or a salt thereof, N-phosphonomethylglycine or a salt thereof, ethylcarbamoylphosphoric acid or a salt thereof, 2-(1-allyloxyaminobutylidene)-5,5-dimethyl-4-methoxycarbonyl-cyclohexane-1,3-dione, 3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea,3-amino-1,2,4-triazole, choline or a salt thereof, and diethylamine or a salt thereof.
