Anti-phytopathogenic sesquiterpenoid-xanthone adducts from potato endophytic fungus Bipolaris eleusines

Abstract

Two sativene sesquiterpenoid-xanthone adducts from potato endophytic fungus Bipolaris eleusines

Bipolenins K–N: New sesquiterpenoids from the fungal plant pathogen Bipolaris sorokiniana

“…Several sativene-type sesquiterpenoids have been previously reported from fungi, including from Bipolaris sp. [1], B. sorokiniana [2], B. eleusines [3–6 8], Cochliobolus sp. [26], Cochliobolus sativus [18], Helminthosporium sativum [20,33–34], Drechslera sp.…”

“…Fungi belonging to the genus Bipolaris (teleomorph: Cochliobolus ) have been reported to produce a diverse array of secondary metabolites, including sesquiterpenes [1–7], sesquiterpene-xanthones [8], diterpenes [9], sesterterpenes [10], cochlioquinones and peptides [11]. Moreover, several of these secondary metabolites are known to play important roles in mediating the virulence of these fungi against plant hosts [12].…”

Psathyrellins A–E, Antibacterial Guanacastane Diterpenoids from Mushroom Psathyrella candolleana

“…These diterpenoids have been detected to possess antibacterial and cytotoxic properties [5][6][7]. As our long-term chemical studies on higher fungi [8][9][10][11][12][13], a chemical investigation on this mushroom resulted in the isolation of five new guanacastane diterpenoids, namely psathyrellins A-E (1-5, Fig. 1).…”

3-Decalinoyltetramic acids from kiwi-associated fungus Zopfiella sp. and their antibacterial activity against Pseudomonas syringae

“…Our recent chemical investigations on endophytic fungi reported a number of bioactive secondary metabolites including terpenoids, cytochalasans, and epsidones. [4][5][6][7] Zopella sp. is an endophytic fungus that was isolated from kiwi plant (Actinidia chinensis Planch).…”
