    Opis:
    Background. Mangrove forests have long been known as a source of phytochemical compounds producing various secondary metabolites. Despite the ubiquitous diversity of polyisoprenoids in the plant kingdom, few studies have focused on the distribution of polyisoprenoids in mangrove plants. The present study describes the distribution and occurrence of a new class of prenyl derivates – polyprenyl acetone as well as other polyisoprenoids in fourteen species of Indonesian mangroves, with an emphasis on chemotaxonomic importance. Material and methods. The leaves and roots of fourteen North Sumatran mangroves were analyzed using two-dimensional thin layer chromatography and electrospray ionization mass spectrometry. Results. In the leaves, the distribution of several types of polyprenyl acetones, polyprenols, and dolichols was detected and classified into types: type-I, having a predominance of dolichols over polyprenols (more than nine-fold), was observed in Acrostichum aureum (younger leaves), Avicennia alba, Av. lanata, Av. officinalis, Bruguiera parviflora, Ceriops tagal, Nypa fruticans, and Rhizophora mucronata; type-II, having the presence of both polyprenols and dolichols, was observed in Acanthus ilicifolius, Acr. aureum, B. cylindrica, and R. apiculata; type-III having a predominance of polyprenols over dolichols (more than nine-fold), was not observed in any North Sumatran mangroves; type-IV, having the presence of both polyprenyl acetones and dolichols, was observed in Aegiceras corniculatum; type-V, having the presence of polyprenyl acetones, polyprenols, and dolichols, was observed in Sonneratia caseolaris and Xylocarpus granatum. In the roots, type-I distribution was observed in Ae. corniculatum, Av. alba, Av. lanata, Av. officinalis, B. parviflora, C. tagal, N. fruticans, R. apiculata, R. mucronata, S. caseolaris, and X. granatum. Type-II distribution was observed in Ac. ilicifolius, Acr. aureum, and B. cylindrica. Type-III, -IV, and -V distributions were not observed in mangrove roots. Cluster analysis demonstrated that polyisoprenoid patterns in the leaves and roots form distinct separation into appropriate genera and tribe, suggesting that mangrove polyisoprenoids are chemotaxonomically significant. Conclusions. The major polyisoprenoid alcohols in Indonesian mangroves were found to be dolichols rather than polyprenols. The diversity of polyisoprenoids in both leaves and roots of mangroves may provide chemotaxonomic marker. The discovery of a new class of polyprenyl acetone is the first report from mangrove plants.

    Opis:
    Geranylgeranoic acid (GGA) and 2,3-dihydrogeranylgeranoic acid (2,3-diGGA) are geranylgeraniol-derived metabolites (Kodaira et al. (2002) J Biochem 132: 327-334). In the present study, we examined the effects of these acids on HL-60 cells. The cells were differentiated into neutrophils by GGA stimulation like retinoic acid stimulation. In the case of cells stimulated with 2,3-diGGA, neutrophils were not detected, but the formation of lipid droplets was induced. On the other hand, when the cells were cultured in the presence of 0.1% FBS instead of 10% FBS, apoptotic cells were induced not only by GGA stimulation but also with 2,3-diGGA. In the latter case, when the cells were cultured in the co-presence of a caspase-3 inhibitor (Ac-DMQD-CHO), the lipid droplets formation was observed in the cells. These results suggest that GGA and 2,3-diGGA are extremely different from each other with respect to their effects on HL-60 cells.

    Opis:
    Dolichols isolated from leaves of the fern Matteucia struthiopteris were present as a mixture of prenologues composed of 14 up to 20 isoprene units with Dol-16 dominating. They comprised approximately 0.004% of the fresh weight of fresh plant tissue and were accompanied by traces of polyprenols (Pren-14 up to Pren-17, Pren-16 dominating). Their structure was confirmed by electropray ionization mass spectrometry (ESI-MS). This is the first time that dolichols have been reported as dominating polyisoprenoid alcohols in plant photosynthetic tissue.
