  • Contact Toxicity and Repellency of the Essential Oil of Dictamnus
           dasycarpus Roots from China against Two Stored‐Product Insects
    • Abstract: During our screening program for new agrochemicals from traditional medicinal herbs, Dictamnus dasycarpus was found to possess contact toxicity and repellent activity against the cigarette beetle Lasioderma serricorne and the booklouse Liposcelis bostrychophila. The essential oil obtained by hydrodistillation of D. dasycarpus roots was characterized by GC‐FID and GC/MS analyses, and the main components identified were syn‐7‐hydroxy‐7‐anisylnorbornene (1, 49.9%), 1,3,4,5,6,7‐hexahydro‐2H‐inden‐2‐one (2, 11.6%), 5,6‐diethenyl‐1‐methylcyclohexene (3, 7.4%), and 3,9‐dimethyltricyclo[4.2.1.12,5]dec‐3‐en‐9‐ol (4, 6.35%). The D. dasycarpus root oil exhibited strong contact toxicity against L. serricorne adults and L. bostrychophila, with LD50 values of 12.4 μg/adult and 27.2 μg/cm2, respectively. Moreover, the essential oil also showed strong repellency against both stored‐product insects tested.
       
  • Free‐Radical‐Scavenging, Antityrosinase, and Cellular
           Melanogenesis Inhibitory Activities of Synthetic Isoflavones
    • Abstract: In this study, we examined the potential of synthetic isoflavones for application in cosmeceuticals. Twenty‐five isoflavones were synthesized and their capacities of free‐radical‐scavenging and mushroom tyrosinase inhibition, as well as their impact on cell viability of B16F10 murine melanoma cells and HaCaT human keratinocytes were evaluated. Isoflavones that showed significant mushroom tyrosinase inhibitory activities were further studied on reduction of cellular melanin formation and antityrosinase activities in B16F10 melanocytes in vitro. Among the isoflavones tested, 6‐hydroxydaidzein (2) was the strongest scavenger of both ABTS.+ and DPPH. radicals with SC50 values of 11.3±0.3 and 9.4±0.1 μM, respectively. Texasin (20) exhibited the most potent inhibition of mushroom tyrosinase (IC50 14.9±4.5 μM), whereas retusin (17) showed the most efficient inhibition both of cellular melanin formation and antityrosinase activity in B16F10 melanocytes, respectively. In summary, both retusin (17) and texasin (20) exhibited potent free‐radical‐scavenging capacities as well as efficient inhibition of cellular melanogenesis, suggesting that they are valuable hit compounds with potential for advanced cosmeceutical development.
       
  • New Isoprenylated Phenolic Compounds from Morus laevigata
    • Abstract: Two new isoprenylated flavonoids, laevigasins A and B (1 and 2, resp.), and one new isoprenylated 2‐arylbenzofuran, leavigasin C (3), together with eight known compounds, 4–11, were isolated from the twigs of Morus laevigata. Their structures were elucidated by spectroscopic methods. Laevigasin A (1) showed significant inhibitory effect on α‐glucosidase in vitro. Notabilisin E (5), taxifolin (10), and hultenin (11) inhibited PTP1B phosphatase activity in vitro.
       
  • New 3,4‐Secocycloartane and 3,4‐Secodammarane Triterpenes from
           the Ecuadorian Plant Coussarea macrophylla
    • Abstract: Coussarea macrophylla (Mart.) Müll.Arg. (Rubiaceae) was collected in Ecuador, and the bark was extracted with AcOEt. Chromatographic separation afforded six novel 3,4‐secocycloartane and 3,4‐secodammarane triterpenes, named macrocoussaric acids A–F, together with the known metabolites secaubryenol and 3,4‐secodammara‐4(28),20,24‐triene‐3,26‐dioic acid. The structures of the new compounds were determined on the basis of their spectroscopic data. This is the first report of 3,4‐secocycloartane and 3,4‐secodammarane triterpenes occurring in a Coussarea species. Macrocoussaric acids A and B (2 and 3, resp.) were found to be moderately cytotoxic against five different tumor cell lines.
       
  • StructureActivity Relationships of Antimicrobial Gallic Acid
           Derivatives from Pomegranate and Acacia Fruit Extracts against Potato
           Bacterial Wilt Pathogen
    • Abstract: Bacterial wilts of potato, tomato, pepper, and or eggplant caused by Ralstonia solanacearum are among the most serious plant diseases worldwide. In this study, the issue of developing bactericidal agents from natural sources against R. solanacearum derived from plant extracts was addressed. Extracts prepared from 25 plant species with antiseptic relevance in Egyptian folk medicine were screened for their antimicrobial properties against the potato pathogen R. solancearum by using the disc‐zone inhibition assay and microtitre plate dilution method. Plants exhibiting notable antimicrobial activities against the tested pathogen include extracts from Acacia arabica and Punica granatum. Bioactivity‐guided fractionation of A. arabica and P. granatum resulted in the isolation of bioactive compounds 3,5‐dihydroxy‐4‐methoxybenzoic acid and gallic acid, in addition to epicatechin. All isolates displayed significant antimicrobial activities against R. solanacearum (MIC values 0.5–9 mg/ml), with 3,5‐dihydroxy‐4‐methoxybenzoic acid being the most effective one with a MIC value of 0.47 mg/ml. We further performed a structure–activity relationship (SAR) study for the inhibition of R. solanacearum growth by ten natural, structurally related benzoic acids.
       
  • Probing Metabolite Space of Escherichia coli via Growth Medium Composition
           as Monitored by Two‐Dimensional NMR Spectroscopy
    • Abstract: As for recombinant protein production, Escherichia coli is one of the most frequently employed hosts because it offers a simple and inexpensive, but rapid and high‐yield system in addition to the vast information on its molecular genetics and biology. However, due to its prokaryotic nature, it often fails to produce eukaryotic proteins in a desired form. To devise a systematic way leading to a condition that produces a large amount of usable proteins, we attempted to monitor intracellular metabolites under various conditions, and to link them to recombinant protein production. With such an intention, we identified 31 metabolites from cells grown in different media by using two‐dimensional (2D) NMR spectroscopy. Our results revealed that 1) the level of betaine was low, while that of glutamic acid was high when grown in minimal media; 2) the level of glycerol was constantly high in all cases; 3) the level of oxidized glutathione was lower in Luria broth (LB); and 4) the level of leucine was low in minimal media. We hope this work might shed light onto how to improve production of the target proteins by metabolite profiling.
       
  • Metabolomic Profile of the Genus Inula
    • Abstract: Plants have a long history as therapeutics in the treatment of human diseases and have been used as source of medicines for ages. Searching for new biologically active natural products, many plants and herbs are screened for natural products with pharmacological activities. In this field, the genus Inula, which comprises more than 100 species, several of them being used in traditional medicine, is very important, especially due to the finding that several of the isolated pure secondary metabolites proved to possess important biological activities. Inula species have been reported as rich sources of sesquiterpene lactones, including eudesmanes, germacranes, guaianes, and dimeric structures, and since 2006 ca. 400 secondary metabolites, including more than 100 new natural products, some of them with relevant pharmacological activities, have been identified. Herein, we critically compile and update the information regarding the types of secondary metabolites found in the genus Inula and the progress in their isolation.
       
  • Botanical, Phytochemical, and Anticancer Properties of the Eucalyptus
           Species
    • Abstract: The genus Eucalyptus (Myrtaceae) is mainly native to Australia; however, some species are now distributed globally. Eucalyptus has been used in indigenous Australian medicines for the treatment of a range of aliments including colds, flu, fever, muscular aches, sores, internal pains, and inflammation. Eucalyptus oils containing volatile compounds have been widely used in the pharmaceutical and cosmetics industries for a multitude of purposes. In addition, Eucalyptus extracts containing nonvolatile compounds are also an important source of key bioactive compounds, and several studies have linked Eucalyptus extracts with anticancer properties. With the increasing research interest in Eucalyptus and its health properties, this review briefly outlines the botanical features of Eucalyptus, discusses its traditional use as medicine, and comprehensively reviews its phytochemical and anticancer properties and, finally, proposes trends for future studies.

  • New Caledonia: A ‘Hot Spot’ for Valuable Chemodiversity. Part
           1: Gymnosperms
    • Abstract: The flora of New Caledonia encompasses more than 3,000 species and almost 80% of them are endemic. New Caledonia is considered as a ‘hot spot’ for biodiversity. With the current global loss of biodiversity, and the fact that several drugs and pesticides are becoming obsolete, there is an urgent need to increase sampling and research on new natural products. In this context, we review the chemical information available on New Caledonian native flora from economical perspectives. We expect that a better knowledge of the economic potential will encourage the plantation of native plants for the development of a sustainable economy which will participate in the conservation of biodiversity. In the first part of this review, we discuss the results reported in 18 scientific articles on the chemicals isolated from 23 endemic conifers of New Caledonia. Several bioactive and original products, such as neocallitropsene or libocedrins, have been isolated from these conifers. This review also highlights several groups, such as Podocarpus spp., that are unexplored in New Caledonia despite the fact that they have been described in other countries to contain a wide range of original bioactive compounds. Those plants are considered as priority for future chemical investigations.
