    trans-4-Aminocyclohexanol-2'-amino-α-D-glucopyranosides were prepared which are derivatives of neamine having the 3-amino and 5 and 6 hydroxyl groups of the 2-deoxystreptamine ring replaced with hydrogen. The 2'-amino-α-glycosides were synthesized by the method of LEMIEUX using a chloro nitroso dimer of a glucal and appropriately substituted cyclohexanols. Reductive deblocking of the intermediate 2-oximino derivatives afforded paromamine and neamine analogues. Two examples of 2'-amino-α-glycosides with ring-opened variations of the 2-deoxystreptamine aglycone are described. None of the compounds exhibited betterin vitro antibacterial activity than neamine when compared against Gram-positive and Gram-negative bacteria.

    Four 2-deoxystreptamine (DOS) related compounds including S-11-P, isolated as an intermediate of DOS biosynthesis, were supplemented to the culture of a DOS- mutant of Bacillus circulans. Among the tested aminocyclitol compounds, S-11-P alone was converted to DOS. Addition of other aminocyclitols neither produced antibiotic nor inhibited the incorporation of S-11-P and DOS into butirosins. By these facts, S-11-P was confirmed clearly to be an intermediate of DOS biosynthesis.

    Methods for the synthesis of esters and amides of edeine A were developed and a number of derivatives of this type was obtained and characterized. The antimicrobial activities of the derivatives are comparable to the activity of the native antibiotic and indicate that the presence of free carboxyl group in edeine is not essential for its biological activity.

    New tetracycline analogs modified at position 5, 6 and 2 were synthetized. The 5-deoxy- 5-oxo-derivatives, 2a and 3a, were obtained by DMSO/acetic anhydride oxidation of doxycycline (2) and methacycline (3), respectively; the 6-demethyl-6-hydroxymethyl-6-alpha-hydroxyoxytetracycline (3b) by methacycline oxidation with the KClO3/OsO4 system and the 6-hydroxyanhydrooxytetracycline (4) treating 3b with periodic acid. The 2-ethoxycarbonyl-2-decarboxamidodoxycycline (2b), was synthetized by treating doxycycline nitrile (2c) with EtOH and anhydrous HCl, 2-thiocarboxamide-2-decarboxamidodoxycycline (2d) by reaction of doxycycline with P2Sg in dioxane and 2-aminomethyl-2-decarboxamidodoxycycline (2e) by RANEY-Nickel reduction of 2d. All the synthetized compounds proved to be almost inactive on agar plates both on Gram-positive and Gram-negative bacteria.

    Three cephalosporin derivatives were prepared from 1, 4-dihydro-4-oxypyridine-1-acetic acid. These were the 7-aminocephalosporanic acid (7-ACA) derivative and the compounds with 5-methyl-1, 3, 4-thiadiazol-2-thiol and 1-methyl-1, 2, 3, 4-tetrazole-5-thiol at C-3 of the cephalosporin nucleus. The antibacterial activity of the 7-ACA derivative was comparable to cephalothin, and that of the other two derivatives was comparable to cefazolin. The 7-ACA derivative, compared to cephalothin, was significantly less metabolized, was less protein bound, and had a longer half life.

    A normal phase high performance liquid chromatographic method is presented for the separation and quantitative determination of aclacinomycin A (ACM) and its related compounds classified as anthracycline antibiotics. The sensitive, reliable and reproducible chromatography was achieved on a μ-Porasil column with a mobile phase consisting of chloroform - methanol - acetic acid - water - triethylamine (68: 20: 10: 2: 0.01, v/v). By use of MA144 Ml, one of the ACM analogues, as an internal standard, selectivity of the HPLC method could be retained by virtue of the adjustment of the detecting wavelength to 436 nm. The HPLC method was applicable to monitoring the fermentation and purification processes.

    A number of rifamycin non-producing UV-mutants derived from Nocardia mediterranei strains N813 (rifamycin B producer) and A101) (aro-mutant excreting shikimate derived from strain N813) were found to accumulate an identical complex of aromatic components instead of rifamycin B. The main component of this aromatic complex, product P8/1-OG, was isolated from six of these P--mutant strains and identified spectroscopically as a very early precursor in the biosynthesis of rifamycins.

    Rats immunized with sulbenicillin-ovalbumin (SBPC-OvA) in combination with aluminum hydroxide (alum) and thimerosal-killed Bordetella pertussis produced high levels of anti-SBPC antibodies. Anti-SBPC antibodies were first detected on day 8, reaching the maximum titer on day 12 and rapidly declined thereafter. Anti-SBPC sera obtained on day 13 were sulfhydryllabile and heat-labile. The optimal latent period in the passive cutaneous anaphylaxis (PCA) reaction was 60-72 hours. These results indicate that anti-SBPC antibodies were IgE antibodies. Sprague-Dawley (SD), Wister and F344 rats were equally productive of anti-SBPC antibodies, while SD rats were more productive of anti-cephaloridine (CER) antibodies than Wister and F344 rats did. In SD rats, the IgE antibodies for penicillin G (PCG), ampicillin (ABPC) and SBPC were more easily produced than the IgE antibodies for CER, cefazolin (CEZ) and cephacetrile (CEC).

    Sprague Dawley (SD) rats were immunized with various penicillin-ovalbumin (OvA) in combination with aluminum hydroxide (alum) and thimerosal-killed Bordetella pertussis for the purpose of obtaining rat anti-penicillin IgE sera. In the rat 60-hour passive cutaneous anaphylaxis (PCA) reaction and the hapten inhibition test, a weak cross reaction between penicillin G (PCG) and ampicillin (ABPC) was observed, but no cross reaction was observed between sulbenicillin (SBPC) and other penicillins. Rat anti-6-formamidopenicillanic acid (FPC) IgE serum reacted with PCG-bovine gamma globulin (BGG), ABPC-BGG and SBPC-BGG, but FPC-BGG did not react with rat anti-PCG, anti-ABPC and anti-SBPC IgE sera and the PCA reaction between anti-FPC IgE sera and FPC-BGG was inhibited by FPC, PCG, ABPC and SBPC. These results indicate that the antigenic active sites of PCG, ABPC and SBPC are limited to the acyl side chain moiety of penicillins, while the antigenic active site of FPC is confined to the penicilloyl moiety of the penicillin.

    Sprague Dawley (SD) rats were immunized with various cephalosporin- and penicillinovalbumin (OvA) in combination with aluminum hydroxide (alum) and thimerosal-killed Bordetella pertussis. Anti-cephalosporin IgE antibody production was inferior to anti-penicillin IgE antibody production. Cefsulodin (CFS), sulbenicillin (SBPC) and α-sulfophenyl acetic acid (SPAA) cross-reacted with each other but did not react with cephaloridine (CER), cefazolin (CEZ) and penicillin G (PCG). CER and PCG slightly cross-reacted with each other but did not cross-react with the others tested. Anti-CFS and anti-SBPC IgE sera were related specifically to the SPAA moiety.

    Bestatin is an inhibitor of cell surface-associated aminopeptidase B and leucine aminopeptidase. This microbial product simulates the role of serum as an activator of uridine uptake in quiescent BHK cells. The compound significantly stimulates the incorporation of labelled thymidine into the acid-insoluble fraction of serum-starved Nil 8 cells in the presence of low concentration of serum. The possible mechanisms of these interactions are discussed.

    Diketocoriolin B (DKC), at a very low dose (0.1μg/mouse) or in a low concentration (0.01 ng/culture) augmented antibody formation to sheep red blood cells (SRBC) in vivo and in vitro. The addition of DKC to spleen cell cultures 24-48 hours after the start of the culture showed the strongest effect. The stimulatory effect was not influenced by the elimination of macrophages. DKC also augmented antibody formation in T cell-depleted spleen cell cultures and in cultures of spleen cells of athyrnic mice. The treatment of spleen cells with DKC at 37°C or 4°C for 30 minutes before the start of the culture enhanced antibody formation to SRBC. Both treatments of macrophage-rich and lymphocyte-rich cells with DKC enhanced antibody formation.

    Binding of aminocyclitol antibiotics to intestinal and kidney brush border membranes has been studied in vitro by means of vesicular preparations. The binding is rapid, reversible, specific, saturable and has a high affinity. To both tissues, gentamicin and sisomicin bind to a single binding site or receptor. These antibiotics demonstrate increased binding under conditions of increasing pH. Membrane binding disappears when the vesicle proteins are denatured with TCA. A significant reduction in aminocyclitol binding after treatment of vesicles with papain indicates that a portion of the binding receptor protein is exposed to the outer surface of the brush border membrane. The accumulated evidence suggests that the nature of the binding mechanism is not a simple electrostatic interaction between the antibiotic's charged amino groups and the polyanions of the membrane. Alternatively, a specific membrane structure is required for binding whose characteristics reflect a drug-receptor interaction. Receptor binding is characterized as being saturable, reversible, and specific; all of which have been demonstrated for aminocyclitols and brush border membranes.
