Abstract
Here, we use transcriptomic data from seeds of Musella lasiocarpa to identify five enzymes involved in the formation of dihydrocurcuminoids. Characterization of the substrate specificities of the enzymes reveals two distinct dihydrocurcuminoid pathways leading to phenylphenalenones and linear diarylheptanoid derivatives, the major seed metabolites. Furthermore, we demonstrate the stepwise conversion of dihydrobisdemethoxycurcumin to the phenylphenalenone 4'-hydroxylachnanthocarpone by feeding intermediates to M. lasiocarpa root protein extract.

Abstract
Foodborne microbial diseases are still considered a growing public health problem worldwide despite the global continuous efforts to ensure food safety. The traditional chemical and thermal-based procedures applied for microbial growth control in the food industry can change the food matrix and lead to antimicrobial resistance. Moreover, currently applied disinfectants have limited efficiency against biofilms. Therefore, antimicrobial photodynamic therapy (aPDT) has become a novel alternative for controlling foodborne pathogenic bacteria in both planktonic and sessile states. The use of aPDT in the food sector is attractive as it is less likely to cause antimicrobial resistance and it does not promote undesirable nutritional and sensory changes in the food matrix. In this review, aspects on the antimicrobial photodynamic technology applied against foodborne pathogenic bacteria and studied in recent years are presented. The application of photodynamic inactivation as an antibiofilm strategy is also reviewed.

Abstract
Concise total syntheses of the natural phytoalexins 2-hydroxy-8-(4-hydroxyphenyl)phenalen-1-one (1), 2-hydroxy-8-(3,4-dihydroxyphenyl)phenalen-1-one (2), and hydroxyanigorufone (4), together with regioisomer 3 are accomplished in 11 or 12 steps. The synthetic strategy features a Friedel-Crafts acylation to construct the 1H-phenalen-1-one tricyclic core followed by a Suzuki cross-coupling to obtain the target compounds.

Abstract
2,4-Dihydroxy-9-phenyl-1H-phenalen-1-one (4-hydroxyanigorufone, 1), a compound isolated from Anigozanthos flavidus and Monochoria elata, displayed a high radical scavenging capacity in the ORAC assay. A systematic approach was adopted in order to explore the effect of each functional group. H-Atom transfer from the phenolic hydroxyl, a captodative effect from the hydroxy ketone, and the presumed involvement of the phenyl ring in the termination step of the radical reaction were disclosed as relevant features of this type of antioxidant.

Abstract
Laser microdissection was used as a tool to harvest secretory cavities (SC) from leaves of Dilatris pillansii Barker (Haemodoraceae) and from leaves and flowers of herbarium specimens of Dilatris corymbosa Berg. and Dilatris viscosa L. Cryogenic (1)H NMR spectroscopy and HPLC analysis of microdissected samples indicated specific accumulation of methoxyphenylphenalenones in the SC. The structures of two novel and a known natural product in the secretory tissue were confirmed by comparison with authentic compounds isolated from rhizomes and roots from which further phenylphenalenones and phenylphenalenone glucosides were isolated and identified by spectroscopic methods. How it will be possible to use the LMD technique to localize natural products in specific plant cell populations is also discussed.

Abstract
Two antifungal phenyl-phenalenone phytoalexins isolated from the banana plant (Musa acuminata) elicited with the fungus Fusarium oxysporum, together with a methoxy derivative of one of them and two epoxide precursors of their chemical synthesis, were tested for leishmanicidal activity on Leishmania donovani promastigotes and L. infantum amastigotes. Drugs inhibited proliferation of both forms of the parasite with a 50% lethal concentration range between 10.3 and 68.7 micro g/ml. Their lethal mechanism was found linked to the respiratory chain by a systematic approach, including electron microscopy, measurement of the oxygen consumption rate on digitonin-permeabilized promastigotes, and enzymatic assays on a mitochondrial enriched fraction. Whereas the whole set of compounds inhibited the activity of fumarate reductase in the mitochondrial fraction (50% effective concentration [EC(50)] between 33.3 and 78.8 micro g/ml) and on purified enzyme (EC(50) = 53.3 to 115 micro g/ml), inhibition for succinate dehydrogenase was only observed for the two phytoalexins with the highest leishmanicidal activity: anigorufone and its natural analogue 2-methoxy-9-phenyl-phenalen-1-one (EC(50) = 33.5 and 59.6 micro g/ml, respectively). These results provided a new structural motif, phenyl-phenalenone, as a new lead for leishmanicidal activity, and support the use of plant extracts enriched in antifungal phytoalexins, synthesized under fungal challenge, as a more rational and effective strategy to screen for new plant leishmanicidal drugs.

Abstract
The light-induced singlet oxygen production and antifungal activity of phenylphenalenone phytoalexins isolated from infected banana plants (Musa acuminata) are reported. Upon absorption of light energy all studied phenylphenalenones sensitise the production of singlet oxygen in polar and non-polar media. Antifungal activity of these compounds towards Fusarium oxysporum is enhanced in the presence of light. These results, together with the correlation of IC50 values under illumination with the quantum yield of singlet oxygen production and the enhancing effect of D2O on the antifungal activity, suggest the intermediacy of singlet oxygen produced by electronic excitation of the phenylphenalenone phytoalexins.

The distribution pattern of phenylphenalenone-type compounds was investigated in vegetative and reproductive organs of Xiphidium caeruleum. The highest total molar concentration, up to 30 micromol g(-1) fr. wt, was detected in the root tip and the stamen. Accumulation of specific phenylphenalenone-related metabolites including glycosides was found in the hypogeal plant parts, the leaves, and the reproductive organs of the inflorescence. Putative biosynthetic relationships and the role of these compounds in plant defence are discussed.

Abstract
Three fused octacyclic phenylphenalenone dimers were isolated from Musa acuminata: Anigorootin, which was first isolated from Anigozanthos flavidus and hitherto represented the only compound of that type, the new 4'-hydroxy-anigorootin, and 4',4"-di-hydroxy-anigorootin, which is a revised structure. The crystal structure of anigorootin was determined by X-ray crystallography. 3,3'-Bis-hydroxyanigorufone, a dimer of the conventional type known from Anigozanthos preissii, was also found in Musa acuminata. Phytochemical analysis of several Haemodoraceae species revealed the occurrence of anigorootin, 3,3'-bis-hydroxyanigorufone, and the novel metabolite 3,3'-bis-anigorufone. The occurrence of the same compounds in Musaceae and Haemodoraceae indicates the close chemotaxonomic relationship of both plant families.

Abstract
A correlation has been established between production of specific phenylphenalenones and resistance of various banana and plantain varieties towards certain pathogens. In addition a dihydrotrihydroxyphenylphenalene was isolated from the resistant 'Pelipita' plantain variety in relatively high concentrations and its structure and relative configuration were assigned on the basis of 1D and 2D NMR and NOE information. This compound is considered a key intermediate in the biosynthesis of phenylphenalenone phytoalexins.

Abstract
Phytoalexins of Musa balbisiana [BBB] cv Saba sa Hapon and cv Mundo fruits were compared with those of M. acuminata [AAA] cv Buñgulan fruits. Phytoalexins induced by wound and inoculation of Colletotrichum musae in these two cultivars were the same as those of Buñgulan. In the course of analysis of the phytoalexins, 2-phenyl-1,8-naphthalic anhydride, 2-(4'-methoxyphenyl)-1,8-naphthalic anhydride, and 1,2,3,4-tetrahydro-6,7-dihydroxy-1-(4'-hydroxycinnamyliden)naphthalen-2-one were found as new phytoalexins of banana fruits. This latter compound is probably a biosynthetic intermediate of phenylphenalenones in banana fruits.
