Abstract
Six compounds previously isolated and reported from Macropidia fuliginosa were evaluated for antimicrobial activity against 11 different microbial strains, with all compounds displaying broad spectrum activity. In addition, the compounds were also assessed for their antiproliferative activity and cytotoxicity. Further investigation of M. fuliginosa has led to the discovery of a previously described acenaphthylenediol from the bulbs of the plant.

Abstract
A critical perspective on phytoanticipins, constitutive plant secondary metabolites with defensive roles against microbes is presented. This mini-review focuses on the chemical groups and structural types of defensive plant metabolites thus far not reviewed from the phytoanticipin perspective: i) fatty acid derivatives and polyketides, ii) terpenoids, iii) shikimates, phenylpropanoids and derivatives, and iv) benzylisoquinoline and pyrrolizidine alkaloids. The more traditional groups of phytoanticipins are briefly summarized, with particular focus on the latest results: i) benzoxazinoids, ii) cyanogenic glycosides, iii) glucosinolates and their metabolic products, and iv) saponins. Current evidence suggests that a better understanding of the functions of plant metabolites will drive their application to protect crops against microbial diseases.

Abstract
Phytochemical investigation of the aerial parts of the monotypic plant, Musella lasiocarpa, led to the isolation of four rare bicyclic diarylheptanoids, musellarins B-E (2–5), two new phenylphenalenones, 2-methoxy-9-(3′,4′-dihydroxyphenyl)-1Hphenalen-1-one (9), 2-methoxy-9-(3′-methoxy-4′-hydroxyphenyl)-1H-phenalen-1-one (10), a new acenaphtylene derivative, trans-(1S,2S)-3-(4′-methoxyphenyl)-acenaphthene-1,2-diol (13), and two new sucrose esters, 1,2′,3′,4′,6′-O-pentaacetyl-3-O-trans-pcoumaroylsucrose (16), 1,2′,3′,4′,6′-O-pentaacetyl-3-O-cis-p-coumaroylsucrose (17), together with nine known compounds. In addition, (4E,6E)-1-(3′,4′-dihydroxyphenyl)-7-(4″-hydroxyphenyl)-hepta-4,6-dien-3-one (15) was isolated for the first time from a natural source. The structures of new compounds were elucidated by analysis of their spectroscopic data. Compounds 2, 6, 8–10, 12, and 14 were cytotoxic toward several of the human tumor cell lines (HL-60, SMMC-7721, A-549, MCF-7, and SW480). Of these, the new compound 9 was the most potent one, with IC50 values of 5.8, 10.3, 6.3, 3.3, and 2.3 µM, respectively. ![]()

Abstract
Experiments were performed to elucidate the excited-state behavior of 9-phenylphenalenones, which are phototoxic plant secondary metabolites involved in mechanisms of light-mediated plant defense. Using a combination of time-resolved and steady-state UV/visible spectroscopies, time-resolved IR absorption spectroscopy, time-resolved singlet oxygen phosphorescence measurements and cyclic voltammetry, we provide evidence of an intramolecular charge-transfer process in the excited singlet and the triplet states of 9-phenylphenalenones that modulates the photosensitized production of singlet oxygen.

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.

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.
