    A new antibiotic, designated FR-900130, has been discovered in the culture filtrate of Streptomyces. The producing organism has been identified as Streptomyces catenulae. The antibiotic was purified by adsorption onto Duolite C-20, passage through Amberlite IRC-50, final purification and desalting on Sephadex G-25. It shows antimicrobial activity against Gram-positive bacteria and synergy with D-cycloserine. The antibiotic is very labile in alkaline solution above pH 8.0 and decomposed during lyophilization or solvent precipitation. It was converted to an acetyl derivative and the biological properties of the derivative were examined.

    A new antibiotic leuseramycin has been isolated from the cultured mycelium of the strain of Streptomyces hygroscopicus TM-531. Physicochemical data, in particular those of 1H- and 13C-NMR spectra, revealed that leuseramycin is closely related to dianemycin in its structure, the former having a methyl group in place of the hydroxymethyl group at C-30. It is active against Gram-positive bacteria, some phytopathogenic fungi and some protozoa.

    An unidentified oligosporic actinomycete strain, No. E864-61, produced two new antibiotics, Bu-2313 A (C27H35NO9) and Bu-2313 B (C26H33NO9). Bu-2313 A and B each exhibited a broad antibiotic spectrum against Gram-positive and Gram-negative anaerobic bacteria, and showed in vivo activity against experimental infections produced by B. fragilis and C. perfringens. Bu-2313 also inhibited some aerobic bacteria such as streptococci. Bu-2313 B was approximately two-fold more active than Bu-2313 A.

    Analogs of Bu-2313 A and B were prepared by C-acylation of tetramic acid derivatives with the dienoic acid moiety obtained by periodate oxidation of Bu-2313 A or B. The C-acylation proceeded in the presence of a strong base such as potassium t-butoxide, sodium hydride or lithium hydride, whereas the use of triethylamine afforded O-acylated products. The semi-synthetic Bu-2313 analogs exhibited antibacterial spectra similar to the parent antibiotic but none exceeded Bu-2313 B in activity.

    A new peptide antibiotic complex, named octapeptin D, was isolated from culture broth of a microorganism belonging to the genus Bacillus. The trihydrochloride of the antibiotic was obtained as a colorless powder, soluble in water and methanol. The empirical formula, C47H88N12O11•3HCl•H2O, was indicated by elemental analysis. Amino acid analysis on the acid hydrolyzate demonstrated the presence of 2, 4-diaminobutyric acid (4 moles), serine (1 mole) and leucine (3 moles). Gas chromatographic analysis with the methylated product of the ethereal extract of the acid hydrolyzate revealed the presence of β-hydroxy isodecanoic acid, β-hydroxy decanoic acid, β-hydroxy isoundecanoic acid and β-hydroxyanteisoundecanoic acid. Octapeptin D is active against Gram-negative and Gram-positive bacteria in vitro and in viva.

    Amino acid analysis of the acid hydrolyzate of octapeptin D revealed the amino acid composition. These amino acids were converted to L-leucyl-derivatives and analyzed by high performance liquid chromatography to clarify their chiralities. These were determined to he: 2, 4-diaminobutyric acid (4L), Ser (D), Leu (2L, 1D). Deacylation with polymyxin acylase afforded deacyl octapeptin D. EDMAN degradation on deacyl octapeptin D revealed the N-terminal amino acid. Application of the chemical cleavage reaction for fragmentation of seryl peptides on tri (DNP)-octapeptin D afforded a DNP-heptapeptide, whose sequence was clarified by EDMAN degradation. Octapeptin D was separated into four components (D1 D2, D3 and D4) by high performance liquid chromatography. All the components were examined for their amino acid and fatty acid compositions. From the results, the structures of octapeptins D1, D2, D3 and D4 were determined.

    Ansamitocins are new maytansinoid antitumor antibiotics produced by an actinomycete strain No. C-15003 (N-1). The organism is characterized by coremia formation on solid media, release of the rod-shaped motile spores with peritrichous flagella in liquid media, the formation of some branched mycelia at a later stage of growth in liquid culture which break up into motile elements, lysozyme resistance, the occurrence of meso-diaminopimelic acid in the cell wall, and guanine-cytosine content of 71±1 mol %. From these results, the organism has been designated as Nocardia sp. No. C-15003 (N-1). In the fermentation fluids, activity against eukaryotic microorganisms was detected. Three of the purified materials, which have the activity against Tetrahymena pyriformis strain W and Hamigera avellanea IFO 7721, were new ansamycin antibiotics with antileukemic activities and were named ansamitocins P-3, P-3' and P-4. Ansamitocins show growth inhibitory activity against several eukaryotic microorganisms but no activity against prokaryotic microorganisms. The acyl moieties at the C-3 position of ansamitocins are essential for their antifungal activities.

    New antibiotics, macbecins I and II, have been found in the culture fluid of an actinomycete, which has the following properties: delayed fragmentation of vegetative mycelia, formation of coremia on solid media, the occurrence of meso-diaminopimelic acid in the cell wall, lysozyme resistance, and guanine-cytosine content of 71±1 mol%. The organism has been designated Nocardia sp. No. C-14919 (N-2001). A marked enhancement of the production of macbecins I and II was observed in cultures containing L-tyrosine. The antibiotics are moderately active against several Gram-positive bacteria and fungi. The antibiotics also inhibit the growth of Tetrahymena pyriformis W at 2μg/ml but show no activity against the regeneration of cilia in partially deciliated Tetrahymena at 10μg/ml.

    Tissue distribution, excretion and metabolism of prumycin in normal mice and rats were studied by microbiological assay. Following the injection of prumycin into mice, high activity was detected and continued for 24 hours in the kidney, and the activity was also high in the skin, uterus, bone, liver, lung and stomach in this order. But concentration in the brain, heart, spleen and testis were too low to detect even 5 minutes after the injection. Prumycin was not inactivated by a variety of tissue homogenates in vitro. Therefore, inability to detect activity of prumycin in the spleen and testis appears to result from poor distribution rather than inactivation by these organs. About 70% of injected prumycin was excreted into rat urine in 24 hours but it was not detectable in feces. When prumycin was injected intravenously into dogs at the dose over 10 mg/kg, vomiting was observed in all animals, and LD50 was about 50 mg/kg.

    The mode of action of prumycin was investigated using synchronized and asynchronous cultured HeLa S-3 cells. Prumycin inhibited significantly the growth of HeLa S-3 cells at the concentration over 5 mcg/nil. DNA synthesis as well as protein synthesis was strongly inhibited at the concentration of 10 mcg/ml of prumycin, but RNA synthesis was not inhibited by the same concentration. Prumycin did not block the transition of the cells from M phase to G1 phase, however, G2 phase cells were blocked clearly by this antibiotic.

    The effect of prumycin on the mouse immune system was studied. Prumycin at a dose of 75 mg/kg (1/2LD50) Showed essentially no suppression of hemolytic plaque forming cells (PFC) against sheep red blood cells (SRBC) when it was administered on day 0, 1 or 2. However, a weak suppression was observed by administration of prumycin on day 3. Also a remarkable suppression of PFC was demonstrated when mouse spleen cells were pre-incubated with prumycin at the concentration over 62.5 mg/kg in vitro. The delayed-type hypersensitivity reaction against SRBC was remarkably suppressed by cyclophosphamide, but it was not much by prumycin, except by administration on the day of elicitation. Prumycin of a high concentration inhibited an uptake of 3H-thymidine by mouse spleen lymphocytes incubated with or without phytohemagglutinin, but that of a low concentration, 1.9-0.03 mcg/ml, slightly increased the blastogenic stimulation of lymphocytes.

    Metabolism and pharmacokinetics of cephaloglycin in man were investigated. High performance liquid chromatographic and gas chromatographic-mass spectrometric analyses of metabolites excreted in human urine following oral administration of cephaloglycin revealed that cephaloglycin was biotransformed in two pathways i.e. elimination of 3-acetyl group and hydrolysis of side chain amide linkage. The former yielded deacetylcephaloglycin, a part of which further underwent lactonization to deacetylcephaloglycin lactone, and the latter led to benzoyl formic acid via phenylglycine. The urinary excretion amounts of these metabolites and intact cephaloglycin were determined by a reversed phase ion pair high performance liquid chromatography. The average total excretion amounts at infinite time accounted for 0.50% of the administered dose for intact cephaloglycin, 17.09% for deacetylcephaloglycin, 0.35 for deacetylcephaloglycin lactone, and 0.86% for benzoyl formic acid. The excretion of phenylglycine was less than 0.2%, its chromatographic peak being too small to allow accurate determination. The rate constants for absorption, metabolism, and urinary excretion were estimated by the moment analysis of the excretion rate-time curves.
