Toure S, Millot M, Ory L, Roullier C, Khaldi Z, Pichon V, Girardot M, Imbert C, Mambu L. Access to Anti-Biofilm Compounds from Endolichenic Fungi Using a Bioguided Networking Screening. J Fungi (Basel) 2022; 8:jof8101012. [PMID: 36294577 PMCID: PMC9604612 DOI: 10.3390/jof8101012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 09/19/2022] [Accepted: 09/20/2022] [Indexed: 11/16/2022] Open
Abstract
Endolichenic microorganisms represent a new source of bioactive natural compounds. Lichens, resulting from a symbiotic association between algae or cyanobacteria and fungi, constitute an original ecological niche for these microorganisms. Endolichenic fungi inhabiting inside the lichen thallus have been isolated and characterized. By cultivation on three different culture media, endolichenic fungi gave rise to a wide diversity of bioactive metabolites. A total of 38 extracts were screened for their anti-maturation effect on Candida albicans biofilms. The 10 most active ones, inducing at least 50% inhibition, were tested against 24 h preformed biofilms of C. albicans, using a reference strain and clinical isolates. The global molecular network was associated to bioactivity data in order to identify and priorize active natural product families. The MS-targeted isolation led to the identification of new oxygenated fatty acid in Preussia persica endowed with an interesting anti-biofilm activity against C. albicans yeasts.

Detection of the first higher plant epoxyalcohol synthase: Molecular cloning and characterisation of the CYP74M2 enzyme of spikemoss Selaginella moellendorffii. PHYTOCHEMISTRY 2018; 156:73-82. [PMID: 30195166 DOI: 10.1016/j.phytochem.2018.08.010] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/05/2017] [Revised: 08/06/2018] [Accepted: 08/17/2018] [Indexed: 05/13/2023]
Abstract
The CYP74M2 gene of a model plant, the spikemoss Selaginella moellendorffii Hieron, was cloned and the catalytic properties of corresponding recombinant protein were studied. The recombinant CYP74M2 protein was active towards 13-hydroperoxides of linoleic and a-linolenic acids (13-HPOD and 13-HPOT, respectively). In contrast to previously studied CYP74M1 and CYP74M3, which possessed the divinyl ether synthase activity, CYP74M2 behaved as a dedicated epoxyalcohol synthase (EAS). For instance, the 13-HPOD was converted to three epimeric oxiranyl carbinols 1-3 (formed at a ratio ca. 4:2:1), namely the (11R,12S,13S), (11R,12R, 13S), and (11S,12S,13S) epimers of (9Z)-11-hydroxy-12,13-epoxy-9-octadecenoic acid. Besides these products, a minority of oxiranyl vinyl carbinols like (10E)-11-hydroxy-12,13-epoxy-9-octadecenoic acid was formed. The 13-HPOT conversion by CYP74M2 afforded two stereoisomers of 11-hydroxy-12,13-epoxy-9,15-octadecadienoic acid. Individual oxylipins were purified by HPLC and finally identified by their NMR data, including the 1H-NMR, 2D-COSY, HSQC, and HMBC. Thus, the CYP74M2 is the dedicated epoxyalcohol synthase. To our knowledge, no enzymes of this type have been detected in higher plants yet.

Abstract
In this study, 19 octadecanoid derivatives-four pairs of enantiomers (1⁻8), two racemic/scalemic mixtures (9⁻10), and nine biosynthetically related analogues-were obtained from the ethanolic extract of a Chinese medicinal plant, Plantago depressa Willd. Their structures were elucidated on the basis of detailed spectroscopic analyses, with the absolute configurations of the new compounds assigned by time-dependent density functional theory (TD-DFT)-based electronic circular dichroism (ECD) calculations. Six of them (1, 3⁻6, and 9) were reported for the first time, while 2, 7, and 8 have been previously described as derivatives and are currently obtained as natural products. Our bioassays have established that selective compounds show in vitro anti-inflammatory activity by inhibiting lipopolysaccharide-induced nitric oxide (NO) production in mouse macrophage RAW 264.7 cells.

Abstract
Enzymes of CYP74 family play the central role in the biosynthesis of physiologically important oxylipins in land plants. Although a broad diversity of oxylipins is known in the algae, no CYP74s or related enzymes have been detected in brown algae yet. Cloning of the first CYP74-related gene CYP5164B1 of brown alga Ectocarpus siliculosus is reported in present work. The recombinant protein was incubated with several fatty acid hydroperoxides. Linoleic acid 9-hydroperoxide (9-HPOD) was the preferred substrate, while linoleate 13-hydroperoxide (13-HPOD) was less efficient. α-Linolenic acid 9- and 13-hydroperoxides, as well as eicosapentaenoic acid 15-hydroperoxide were inefficient substrates. Both 9-HPOD and 13-HPOD were converted into epoxyalcohols. For instance, 9-HPOD was turned primarily into (9S,10S,11S,12Z)-9,10-epoxy-11-hydroxy-12-octadecenoic acid. Both epoxide and hydroxyl oxygen atoms of the epoxyalcohol were incorporated mostly from [18O2]9-HPOD. Thus, the enzyme exhibits the activity of epoxyalcohol synthase (EsEAS). The results show that the EsEAS isomerizes the hydroperoxides into epoxyalcohols via epoxyallylic radical, a common intermediate of different CYP74s and related enzymes. EsEAS can be considered as an archaic prototype of CYP74 family enzymes.

Abstract
Marine algae are rich and heterogeneous sources of great chemical diversity, among which oxylipins are a well-recognized class of natural products. Algal oxylipins comprise an assortment of oxygenated, halogenated, and unsaturated functional groups and also several carbocycles, varying in ring size and position in lipid chain. Besides the discovery of structurally diverse oxylipins in macroalgae, research has recently deciphered the role of some of these metabolites in the defense and innate immunity of photosynthetic marine organisms. This review is an attempt to comprehensively cover the available literature on the chemistry, biosynthesis, ecology, and potential bioactivity of oxylipins from marine macroalgae. For a better understanding, enzymatic and nonenzymatic routes were separated; however, both processes often occur concomitantly and may influence each other, even producing structurally related molecules.

Abstract
In a previous study, we showed that a series of homoisoflavonoids from the stems of Haematoxylon campechianum possess potent protein tyrosine kinase inhibitory activity. In a further chemical investigation of the heartwood of H. campechianum, three new homoisoflavonoids, epihematoxylol B (2), 10-O-methylhematoxylol B (3), and 10-O-methylepihematoxylol B (4), were isolated and identified, together with 15 known compounds, including three homoisoflavonoids, three flavonoids, six lignans, and three unsaturated fatty acids. The structures of the new compounds were established on the basis of 1D- and 2D-NMR and other spectroscopic analyses. Using ELISA method, the new compounds and selected known compounds were tested for protein tyrosine kinase inhibitory activity targeting kinase insert domain receptor. Epihematoxylol B (2) and the known compounds, hematoxylol B (1) and hematoxylin (5), exhibited inhibitory rates of 92.22.3, 71.31.1, and 94.81.6, respectively, at 10 μM concentration.

Abstract
The present study investigated the contents of hydroxy-oxylipins hydroxyoctadecadienoic acids (HODEs), hydroxyoctadecatrienoic acids (HOTrEs), and hydroxyeicosatetraenoic acids (HETEs) in 40 macroalgae belonging to the Chlorophyceae, Rhodophyceae and, Phaeophyceae. The hydroxy-oxylipin content was low and ranged from 0.14 ± 0.012 ng/g (Codium dwarkense) to 8,161.9 ± 253 ng/g (Chaetomorpha linum) among the Chlorophyceae, 345.4 ± 56.8 ng/g (Scytosiphon lomentaria) to 2,574.5 ± 155.5 ng/g (Stoechospermum marginatum) among the Phaeophyceae, and 19.4 ± 2.2 ng/g (Laurencia cruciata) to 1,753.1 ± 268.2 ng/g in Gracilaria corticata v. folifera) among the Rhodophyceae on fresh weight basis (p ≤ 0.01). The concentrations of C18-oxylipins were greater than C20-oxylipins in all the investigated macroalgae, except forUlva linza, Codium sursum, Dictyopteris deliculata, S. marginatum, Sargassum tenerrimum, Gracilaria spp. (except G. textorii), Rhodymenia sonderi, and Odonthalia veravalensis.The macroalgal species rich in HODEs, HOTrEs, and HETEs were segregated using principal component analysis. The red macroalgae showed the highest contents of HETEs, followed by brown and green macroalgae in consistent with their PUFA profiles. The relative contents of isomeric forms of oxylipins displayed the species-specific positional selectivity of lipoxygenase (LOX) enzyme in macroalgae. All the species exhibited 13-LOX specificity for linoleic acid analogous of higher plants, while 21 out of 40 species showed 9-LOX selectivity for the oxygenation of α-linolenic acid. No trend was observed for the oxygenation of arachidonic acid in macroalgae, except for in the Halymeniales, Ceramiales (except L. cruciata), and Corallinales. This study infers that LOX products, octadecanoids and eicosanoids, described in macroalgal taxa were similar to those of higher plants and mammals, respectively, and thus can be utilized as an alternative source of chemically synthesized oxylipin analogues in therapeutics, cosmetics, and nutritional oil supplements.

Abstract
In recent years, oxylipins (lipoxygenase-derived oxygenated fatty acid products) have been reported in several bloom-forming marine diatoms. Despite increasing attention on the ecophysiological role of these molecules in marine environments, their biosynthesis is largely unknown in these microalgae. Biochemical methods, including tandem mass spectrometry, nuclear magnetic resonance and radioactive probes were used to identify structures, enzymatic activities and growth-dependent modulation of oxylipin biosynthesis in the pennate diatom Pseudo-nitzschia delicatissima. Three major compounds, 15S-hydroxy-(5Z,8Z,11Z,13E,17Z)-eicosapentaenoic acid (15S-HEPE), 15-oxo-5Z,9E,11E,13E-pentadecatetraenoic acid and 13,14-threo-13R-hydroxy-14S,15S-trans-epoxyeicosa-5Z,8Z,11Z,17Z-tetraenoic acid (13,14-HEpETE), were produced by three putative biochemical pathways triggered by eicosapentaenoic acid-dependent 15S lipoxygenase. Oxylipin production increases along the growth curve, with remarkable changes that precede the demise of the culture. At least one of the compounds, namely 15-oxoacid, is formed only in the stationary phase immediately before the collapse of the culture. Synthesis and regulation of phyco-oxylipins seem to correspond to a signaling mechanism that governs adaptation of diatoms along the growth curve until bloom termination. Factors triggering the process are unknown but synthesis of 15-oxoacid, constrained within a time-window of a few days just before the collapse of the culture, implies the involvement of a physiological control not directly dependent on distress or death of diatom cells.

Abstract
The oxylipin chemistry of the temperate red alga Polyneura latissima has been investigated. The structures of three novel oxylipins, 8-[1'(Z),3'(Z),6'(Z)-dodecatriene-1'-oxy]- 5(Z),7(E)-octadienoic acid, 7(S*)-hydroxy-8(S*),9(S*)-epoxy-5(Z),11(Z),14(Z)-eicosatrienoic acid, 7(R*)-hydroxy-8(S*),9(S*)-epoxy-5(Z),11(Z),14(Z)-eicosatrienoic acid, together with two known eicosanoids, 9(S)-hydroxy-5(Z),7(E),11(Z),14(Z)-eicosatetraenoic acid, and 9,15-dihydroxy-5(Z),7(E),11(Z),13(E)-eicosatetraenoic acid, were elucidated by spectroscopic methods and chemical degradation. The oxygenation pattern of these oxylipins suggests that P. latissima metabolizes polyunsaturated fatty acids via a 9(S)-lipoxygenase.

Abstract
Marine organisms, especially marine algae, are extremely rich in a diversity of novel oxylipin structures. Many of these oxylipins contain functionalities and rings of a type and location unknown in mammalian systems. In this perspective reviewing marine oxylipins, a proposal is formulated for the central intermediacy of an epoxy allylic carbocation in the biogenesis of these diverse structures. This proposal is strengthened by the relatively large number of examples which are consistent with this type of mechanistic transformation.

Abstract
Diverse marine life, including algae, sponges, molluscs, corals, tunicates, and bacteria, have been found to possess a variety of structurally unique oxylipins. The algae are the best characterized of these organisms for their oxylipins, which have now been described from more than 30 species representing the three major groups of macrophytic algae (Rhodophyta = reds, Chlorophyta = greens, and Phaeophyceae = browns). A number of recent studies have sought to understand the biosynthetic origin and mechanistic chemistry which leads to the formation of these unique marine substances. In general, the red algae metabolize C20 acids via 12-lipoxygenase-initiated pathways, green algae metabolize C18 acids at C-9 and C-13, and brown algae metabolize both C18 and C20 acids, principally by lipoxygenases with n-6 specificity. This review updates the records of new oxylipins from marine algae and describes thoughts on their biogenesis as well as specific experiments aimed at probing these hypotheses.

Abstract
In a survey of antifungal stress compounds induced by cupric chloride we found that leaves of Chenopodium album exuded a highly fungitoxic metabolite mucondialdehyde (trans-2,trans-4-hexadienedial), which was associated with 13-oxo-9,11-tridecadienoic acids (cis-9,trans-11 and trans-9,trans-11 isomers) presumably resulting from beta-scission of 13-hydroperoxy-octadecadi(tri)enoic acid. The biogenesis and role as a general defensive agent in plants are briefly discussed.
