Structural Characterization of Lipopeptide Methyl Esters Produced by Bacillus licheniformis HSN 221
Authors: Li Yiming , Yang Shizhong , Mu Bozhong 
Published: August 2010

AbstractLipopeptides and their analogues are of increasing interest due to their amphiphilic structures and potential applications in various fields. Three purified lipopeptides analogues were obtained at the same time after two‐step column‐chromatographic purification from cell‐free broth cultivated by Bacillus licheniformis HSN 221. Analysis by ESI‐MS, GC/MS, HPLC, and Q‐TOF MS/MS revealed their primary structures as anteiso‐C15‐ and iso‐C15‐β‐hydroxy fatty acid‐Gln‐Leu‐Leu‐Val‐MeAsp‐Leu‐Ile, anteiso‐C15‐ and iso‐C15‐β‐hydroxy fatty acid‐MeGlu‐Leu‐Leu‐Val‐Asp‐Leu‐Ile and iso‐C16‐β‐hydroxy fatty acid‐Glu‐Leu‐Leu‐Val‐MeAsp‐Leu‐Ile, respectively. The production of two surfactin monomethyl esters and one lichenysin monomethyl ester directly from microorganisms is helpful to understand the variants of metabolites.
Chemical Diversity in the Genus Alpinia (Zingiberaceae): Comparative Composition of Four Alpinia Species Grown in Northern India
Authors: Padalia Rajendra C. , Verma Ram S. , Sundaresan Velusamy , Chanotiya Chandan S. 
Published: August 2010

AbstractThe essential‐oil compositions of leaves, flowers, and rhizomes of Alpinia galanga (L.) Willd., Alpinia calcarata Rosc., Alpinia speciosa K. Schum., and Alpinia allughas Rosc. were examined and compared by capillary GC and GC/MS. Monoterpenoids were the major oil constituents identified. 1,8‐Cineole, α‐terpineol, (E)‐methyl cinnamate, camphor, terpinen‐4‐ol, and α‐ and β‐pinenes were the major constituents commonly distributed in leaf and flower essential oils. The presence of endo‐fenchyl acetate, exo‐fenchyl acetate, and endo‐fenchol was the unique feature of rhizome essential oils of A. galanga, A. calcarata, and A. speciosa. On contrary, the rhizome oil of A. allughas was dominated by β‐pinene. Significant qualitative and quantitative variations were observed in essential‐oil compositions of different parts of Alpinia species growing in subtemperate and subtropical regions of Northern India. Cluster analysis was performed to find similarities and differences in essential‐oil compositions based on representative molecular skeletons. Monoterpenoids, viz., 1,8‐cineole, terpinen‐4‐ol, camphor, pinenes, (E)‐methyl cinnamate, and fenchyl derivatives, were used as chemotaxonomic markers.
Bioactivity of Amphitoxin, the Major Constituent of the Jamaican Sponge Amphimedon compressa

Published: August 2010

AbstractFractionation of the MeOH/CH2Cl2 extract of the sponge Amphimedon compressa afforded the secondary metabolite amphitoxin (1), the structure of which was elucidated by interpretation of 1H‐ and 13C‐NMR data. The crude extract and the fractions containing the metabolite 1 were assessed for ichthyotoxic and insecticidal activity towards Xiphophorus variatus (moon fish) and Cylas formicarius elegantulus (sweet potato weevil), respectively. In addition, the ability of 1 to cause mortality (toxicity and lethal effect) in the rodent Rattus norvegicus (Norway rat) was examined. Moderate insecticidal activity was observed, while the toxicity towards the moon fish was evidenced by the high mortality rates for all the fractions tested. In contrast, the rodent was not affected by the metabolite.
Antitumor‐Promoting Effects and Cytotoxic Activities of Dammar Resin Triterpenoids and Their Derivatives

Published: August 2010

AbstractNineteen known triterpenoids, 1–19, and one known sesquiterpenoid, 20, were isolated from dammar resin obtained from Shorea javanica K. & V. (Dipterocarpaceae). One of the acidic triterpenoids, dammarenolic acid (1), was converted to fourteen derivatives, namely, an alcohol, 21, an aldehyde, 22, and twelve L‐amino acid conjugates, 23–34. Compounds 1–34 were examined for their inhibitory effects on the induction of Epstein–Barr virus early antigen (EBV‐EA) by 12‐O‐tetradecanoylphorbol 13‐acetate (TPA) in Raji cells, a known primary screening test for antitumor promoters. All of the compounds tested, except for compounds 4, 5, 12–14, 16, and 17, showed inhibitory effects against EBV‐EA activation with potencies either comparable with or stronger than that of β‐carotene, a known natural antitumor promoter. In addition, (20S)‐20‐hydroxy‐3,4‐secodammara‐4(28),24‐dien‐3‐al (22) exhibited inhibitory effects on skin tumor promotion in an in vivo two‐stage mouse skin carcinogenesis test based on 7,12‐dimethylbenz[a]anthracene (DMBA) as initiator, and with TPA as promoter. Furthermore, evaluation of the cytotoxic activities of compounds 1–34 against human cancer cell lines showed that reduction (i.e., 21 and 22) or conjugation with L‐amino acids (i.e., 23–34) of compound 1 enhanced the cytotoxicity against human melanoma cell line CRL1579.
