    Notes: Monoclonal antibodies against the lipopolysaccharide (LPS) of the deep rough mutant I-69 Rd−/b+ of Haemophilus influenzae were obtained after immunization of mice with sheep erythrocytes which had been coated with de-O-acylated LPS. Characterization of antibodies was performed by enzyme immuno assay (EIA) using LPS or neoglycoconjugates containing partial structures of LPS as solid-phase antigens and by haemagglutination with sheep erythrocytes coated with de-O-acylated LPS. Binding data were confirmed by EIA inhibition experiments using deacylated LPS or synthetic partial structures thereof. Three antibodies were specific for 3-deoxy-d-manno-octulopyranosonic acid- (Kdo) 5-phosphate, one for Kdo-4-phosphate, and one required, in addition to a Kdo-phosphate, parts of the phosphorylated glucosamine backbone of lipid A. All antibodies also bound in (i) Western blots to bacterial whole-cell lysates or isolated LPS separated by SDS–PAGE, (ii) bacterial colony blots, and (iii) immunofluorescence with live bacteria. The latter result indicated that Kdo-4- and Kdo-5-phosphate are synthesized by the bacteria and are not the result of phosphate migration.

    Notes: The antigen-binding fragments (Fab) of two murine monoclonal antibodies (mAb) S25-2 and S45-18, specific for carbohydrate epitopes in the lipopolysacchaide of the bacterial family Chlamydiaceae, have been crystallized in the presence and absence of synthetic oligosaccharides corresponding to their respective haptens. Crystals of both Fabs show different morphology depending on the presence of antigens. The sequence of mAb S45-18 was determined and shows a remarkable homology to that reported for mAb S25-2. These crystals offer an unparalleled opportunity to compare the structure and modes of binding of two homologous antibodies to similar but distinct carbohydrate epitopes.

    Notes: Abstract An artificial glycoconjugate containing, as a ligand, the deacylated carbohydrate backbone of a recombinant Chlamydia-specific lipopolysaccharide was used as a solid-phase antigen in ELISA to measure antibodies against chlamydial LPS. The specificity and reproducibility of the assay was shown by using a panel of prototype monoclonal antibodies representing the spectrum of antibodies also occuring in patient sera. These mAbs recognized Chlamydia-specific epitopes [α2→8-linked disaccharide of 3-deoxy-d-manno-octulosonic acid (Kdo) or the trisaccharide αKdo-(2→8)-→Kdo] or those shared between chlamydial and Re-type LPS (αKdo, α→4-linked Kdo disacccharide). The assay was used to measure IgG, IgA and IgM antibodies against chlamydial LPS in patients with genital or respiratory tract infections. In comparison to the results obtained with sera from blood donors, it became evident that both types of infection result in significant changes in the profile of LPS antibodies.

    Notes: Abstract By reaction of several N-phenyl-benzamidrazones with SO2F2 2-phenyl-2,5-dihydro-1,2,3,5-thiatriazole-1,1-dioxides2 a–c are formed. By reaction of N,N-diethyl-N′-chlorosulfonyl-chloroformamidine8 with hydrazines the corresponding 4-diethylamino-substituted derivatives9 a–d are obtained. Methylation of2 b yields two isomeric products5 and6, whereas by methylation of9 d only one product9 b is obtained.

    Notes: Abstract 2,5-Dihydro-1,2,3,5-thiatriazole-1,1-dioxides2 a–2 c were obtained on treating N1-acyl-sulfamoylhydrazides with PCl5, yielding the corresponding N2-sulfamoyl-carbohydrazonoylchlorides which cyclized after addition of KOH orn-butyllithium. Methylation of2 c yields2 b and the 2,3-isomer10 in a 1 : 1 ratio. Reaction of the nitrilimine11 with the N-sulfonylamine12 affords the tetrazine13 and the isomeric dihydrothiatriazole-1,1-dioxides14 and15 via 1,3-dipolar cycloaddition reaction, while the dihydro-1,2,3,5-thiatriazole-1,1-dioxid16 reacts with ethyl chloroformate to yield the isomers14 and17.

Reaction of several dibenzylidene sulfamides1 with various lithium-amides gives N1-substituted N2-benzylsulfamoyl-benzamidines7 a-k via an intramolecular hydride transfer reaction, whereas by treatment of1 a with sodium amide 2-benzyl-3,5-diphenyl-3,4-dihydro-2H-1,2,4,6-thiatriazine-1,1-dioxide8 is obtained, which on hydrolysis yields9 and11. Alkylation products are described, the isomeric products12a/13a and12b/13b are isolated, their structures are confirmed by synthesis, IR and NMR-spectra.
