  • Antibacterial Activity of Enrofloxacin and Ciprofloxacin Derivatives of
           β‐Octaarginine
    • Authors: Nirupam Purkayastha; Stefania Capone, Albert K. Beck, Dieter Seebach, Jennifer Leeds, Katherine Thompson, Heinz E. Moser
      First page: 179
      Abstract: β3‐Octaarginine chains were attached to the functional groups NH and CO2H of the antibacterial fluoroquinolones ciprofloxacin (→1) and enrofloxacin (→2), respectively, in order to find out whether the activity increases by attachment of the polycationic, cell‐penetrating peptide (CPP) moiety. For comparison, simple amides, 3–5, of the two antimicrobial compounds and β3‐octaarginine amide (βR8) were included in the antibacterial susceptibility tests to clarify the impact of chemical modification on the microbiological activity of either scaffold (Table).

  • Effect of Aglycon Structure on Saccharide Elongation by Cells
    • Authors: Tamami Kimura; Maria Carmelita Z. Kasuya, Kenichi Hatanaka, Koji Matsuoka
      First page: 239
      Abstract: Alkyl N‐acetyl‐β‐D‐glucosaminide (GlcNAc primers) with different aglycon moieties were synthesized and used to determine the effect of the aglycon structure on cellular saccharide elongation. Dodecyl N‐acetyl‐β‐D‐glucosaminide (GlcNAc‐C12), tridecan‐7‐yl N‐acetyl‐β‐D‐glucosaminide (GlcNAc‐2C6), and pentacosan‐13‐yl N‐acetyl‐β‐D‐glucosaminide (GlcNAc‐2C12) primers were synthesized by glycosylation of dodecan‐1‐ol, tridecan‐7‐ol, and pentacosan‐13‐ol, respectively, with peracetylglucosamine. These primers were introduced to mouse B16 melanoma cells to prepare glycolipids. After 48 h incubation, results showed that GlcNAc‐C12 was elongated to give NeuAc‐Gal‐GlcNAc‐C12. GlcNAc‐2C6 was also elongated to afford Gal‐GlcNAc‐2C6 and NeuAc‐Gal‐GlcNAc‐2C6. On the other hand, GlcNAc‐2C12 primer was not elongated. Significantly, the results demonstrated that the amount of glycosylated product increased 1.5‐times by modifying the aglycon structure of GlcNAc from C12 to 2 C6 despite having almost the same number of C‐units.

  • Butane‐2,3‐dione: the Key Contributor to Axillary and Foot
           Odor Associated with an Acidic Note
    • Authors: Takeshi Hara; Ayumi Kyuka, Hironori Shimizu
      First page: 248
      Abstract: Human body odor, which contains several volatile organic compounds, possesses various odor qualities. To identify key volatile compounds responsible for the common unpleasant odors derived from human axillae and feet, the odor quality and intensity of 118 human axillae and feet were directly evaluated by sniffing, and odor compounds obtained from the subjects were identified. Furthermore, the sensory differences in odor intensity and quality with and without addition of butane‐2,3‐dione were evaluated by using the visual analog scale (VAS). An acidic odor was a common unpleasant note in human axillae and feet. Butane‐2,3‐dione was identified as a key compound associated with this odor. Strong positive correlations between the amount of butane‐2,3‐dione, and the odor intensities of axillae and feet were observed, and the addition of butane‐2,3‐dione solution to blended short‐chain fatty‐acid solutions caused significantly increased VAS values of axillary‐like odor, unpleasantness, and odor intensity compared to those of each solution without added butane‐2,3‐dione.

  • Activities of Wogonin Analogs and Other Flavones against Flavobacterium
           columnare
    • Authors: Cheng‐Xia Tan; Kevin K. Schrader, Ikhlas A. Khan, Agnes M. Rimando
      First page: 259
      Abstract: In our on‐going pursuit to discover natural products and natural product‐based compounds to control the bacterial species Flavobacterium columnare, which causes columnaris disease in channel catfish (Ictalurus punctatus), we synthesized flavone and chalcone analogs, and evaluated these compounds, along with flavonoids from natural sources, for their antibacterial activities against two isolates of F. columnare (ALM‐00‐173 and BioMed) using a rapid bioassay. The flavonoids chrysin (1a), 5,7‐dihydroxy‐4′‐methoxyflavone (11), isorhamnetin (26), luteolin (27), and biochanin A (29), and chalcone derivative 8b showed strong antibacterial activities against F. columnare ALM‐00‐173 based on minimum inhibition concentration (MIC) results. Flavonoids 1a, 8, 11, 13 (5,4′‐dihydroxy‐7‐methoxyflavone), 26, and 29 exhibited strong antibacterial activities against F. columnare BioMed based upon MIC results. The 24‐h 50% inhibition concentration (IC50) results revealed that 27 and 29 were the most active compounds against F. columnare ALM‐00‐173 (IC50 of 7.5 and 8.5 mg/l, resp.), while 26 and 29 were the most toxic compound against F. columnare BioMed (IC50 of 9.2 and 3.5 mg/l, resp.). These IC50 results were lower than those obtained for wogonin against F. columnare ALM‐00‐173 and F. columnare BioMed (28.4 and 5.4 mg/l, resp.). However, based on MIC results, none of the compounds evaluated in this study were as active as wogonin (MIC 0.3 mg/l for each F. columnare isolate). Further modification of the wogonin structure to enhance antibacterial is of interest.

  • Cyclopentenone Derivatives and Polyhydroxylated Steroids from the Soft
           Coral Sinularia acuta
    • Authors: Nai‐Xia Zhang; Xu‐Li Tang, Leen van Ofwegen, Lei Xue, Wen‐Juan Song, Ping‐Lin Li, Guo‐Qiang Li
      First page: 273
      Abstract: Four new polyhydroxylated steroids, 1–4, and the racemic form of cyclopentenone 9, together with four known steroids, 5–8, one known cyclopentenone derivative, 10, and one known butenolide derivative, 11, were isolated from the soft coral Sinularia acuta collected from Weizhou Island of Guangxi Province, P. R. China. Their structures were elucidated on the basis of spectroscopic analyses and by comparison of the corresponding data with those previously reported. The cytotoxicities of the isolates 1–11 in vitro against the selected tumor cell lines HL‐60, HeLa, and K562 were evaluated. Compounds 2 and 5 showed potent cytotoxicities against HL‐60 cell lines with IC50 values of 7.3 and 9.9 μM, respectively. Compounds 5 and 6 showed moderate activities against K562 cell lines with IC50 values of 10.9 and 11.7 μM, respectively, while compounds 1, 2, and 6 showed weak activities against HeLa cell lines with respective IC50 values of 44.8, 27.1, and 18.2 μM. This is the first report on chemical and bioactivity research of S. acuta.

  • Microsphaerol and Seimatorone: Two New Compounds Isolated from the
           Endophytic Fungi, Microsphaeropsis sp. and Seimatosporium sp.
    • Authors: Hidayat Hussain; Natalia Root, Farah Jabeen, Ahmed Al‐Harrasi, Manzoor Ahmad, Fazal Mabood, Zahid Hassan, Afzal Shah, Ivan R. Green, Barbara Schulz, Karsten Krohn
      First page: 289
      Abstract: A new polychlorinated triphenyl diether named microsphaerol (1), has been isolated from the endophtic fungus Microsphaeropsis sp. An intensive phytochemical investigation of the endophytic fungus Seimatosporium sp., led to the isolation of a new naphthalene derivative named seimatorone (2) and eight known compounds, i.e., 1‐(2,6‐dihydroxyphenyl)‐3‐hydroxybutan‐1‐one (3), 1‐(2,6‐dihydroxyphenyl)butan‐1‐one (4), 1‐(2‐hydroxy‐6‐methoxyphenyl)butan‐1‐one (5), 5‐hydroxy‐2‐methyl‐4H‐chromen‐4‐one (6), 2,3‐dihydro‐5‐hydroxy‐2‐methyl‐4H‐chromen‐4‐one (7), 8‐methoxynaphthalen‐1‐ol (8), nodulisporins A and B (9 and 10, resp.), and daldinol (11). The structures of 1 and 2 were elucidated by detailed spectroscopic analysis including 1H‐ and 13C‐NMR, COSY, HMQC, HMBC, and HR‐EI‐MS, while the structures of the known compounds were deduced from comparison of their spectral data with those in the literature. Preliminary studies revealed that microsphaerol (1) showed good antibacterial activities against B. Megaterium and E. coli, and good antilagal and antifungal activities against C. fusca, M. violaceum, respectively. On the other hand, seimatorone (2) exhibited moderate antibacterial, antialgal, and antifungal activities.

  • Population Variability of Essential Oils of Pinus heldreichii from the
           Scardo‐Pindic Mountains Ošljak and Galičica
    • Authors: Biljana Nikolić; Mihailo Ristić, Srdjan Bojović, Zoran Krivošej, Vlado Matevski, Petar D. Marin
      First page: 295
      Abstract: The needle‐terpene profiles of two natural Pinus heldreichii populations from Mts. Ošljak and Galičica (Scardo‐Pindic mountain system) were analyzed. Among the 68 detected compounds, 66 were identified. The dominant constituents were germacrene D (28.7%), limonene (27.1%), and α‐pinene (16.2%). β‐Caryophyllene (6.9%), β‐pinene (5.2%), β‐myrcene (2.3%), pimaric acid (2.0%), α‐humulene (1.2%), and seven additional components were found to be present in medium‐to‐high amounts (0.5–10%). Although the general needle‐terpene profile of the population from Galičica was similar to those of the populations from Lovćen, Zeletin, Bjelasica, and Zlatibor‐Pešter (belonging to the Dinaric Alps), the principle‐component analysis (PCA) of seven terpenes (β‐myrcene, limonene, β‐elemene, β‐caryophyllene, α‐humulene, δ‐cadinene, and germacrene D‐4‐ol) in 121 tree samples suggested a partial divergence in the needle‐terpene profiles between the populations from the Scardo‐Pindic mountain system and the Dinaric Alps. According to previously reported data, the P. heldreichii samples from the Balkan‐Rhodope mountains lack β‐caryophyllene and germacrene D, but contain γ‐muurolene in their terpene profile. Differences in the terpene composition between populations growing in the three above‐mentioned mountain systems were compared and discussed.
