SK&F 75073, a new parenteral cephalosporin, was found to have broad in vitro and in vivo antibacterial activity including isolates usually resistant to cephalothin and cefazolin. This activity included indole-positive Proteus and Enterobacter species and some Serratia isolates. Proteus mirabilis strains were particularly susceptible, as were Haemophilus(More)
Cyclic and acyclic analogs of tetrahydrodipicolinate (THDPA) are evaluated in a study of the active site of succinyl-CoA:tetrahydrodipicolinate N-succinyltransferase. In addition to the natural substrate, THDPA, one cyclic and several acyclic compounds are also succinylated. 2-Hydroxytetrahydropyran-2,6-dicarboxylic acid is a potent competitive inhibitor(More)
Sulfanilic acid, in contrast to sulfanilamide, has poor in vitro antibacterial activity. Paradoxically, it has been shown to be a more effective inhibitor than sulfanilamide of dihydropteroic acid synthase. In order to circumvent the presumed permeability barrier to sulfanilic acid, advantage was taken of the technique of portage transport. Derivatives of(More)
Succinyl-CoA:tetrahydrodipicolinate-N-succinyltransferase is a key enzyme in the biosynthesis of diaminopimelic acid (DAP), a component of the cell wall peptidoglycan of nearly all bacteria. This enzyme converts the cyclic precursor tetrahydrodipicolinic acid (THDPA) to a succinylated acyclic product. L-2-Aminopimelic acid (L-1), an acyclic analogue of(More)
Cefatrizine (SK&F 60771), a new orally-active semisynthetic cephalosporin antibiotic with broad-spectrum antibacterial activity, was compared with cephalexin and cefazolin for in vitro and in vivo antibacterial activity and pharmacokinetic behavior in laboratory animals. The average MIC values obtained with cefatrizine against gram-positive and(More)

An 10 gesunden Sportstudenten wurde der Tagesgang der Muskelaktivität an der mittleren Amplitude der Muskelaktionspotentiale verfolgt. Im Vordergrund der Tagesschwankungen fand sich eine 12stündige Periodik, die sich bezüglich Phasenlage und Amplitude weitgehend wie entsprechende Tageskurven anderer Organfunktionen verhielt. Zwischen Tagesmittelwert(More)
The synthesis of a series of related broad-spectrum 7-phenylglycyl cephalosporins with 3-heterocyclicthiomethyl substituents is described. The effects of benzene-ring hydroxylation and 3-substituent variation on the in vitro antibacterial activity, height and duration of mouse serum levels, and effectiveness in protecting against bacterial infection in the(More)
