چکیده
In the course of our previous work we isolated alkaloids such as agroclavine-I and epoxy-agroclavine-I from Penicillium citrinum VKM FW-800 as a microorganism isolated from permafrost1,2). This fungus was shown to coproduce two other alkaloid compounds, which were extractable only under acidic conditions. Positive staining by Dragendorff's reagent but negative Ehrlich reaction suggested the occurrence of unusual alkaloid structures. Here we report isolation and structure elucidation of

I t has been known for some time that Penicillium citrinum Thom when grown on suitable media produces a characteristic lemon yellow colour. Thus Thom in his monograph on “ Cultural Studies of species of 1910), says, “ P. citrinum produces a lemon yellow colour, soluble in alcohol, in media containing sugars, milk, gelatin, bread and potato.” This colouring matter was not isolated, however, nor ...
متن کاملAlkaloids and polyketides from Penicillium citrinum, an endophyte isolated from the Moroccan plant Ceratonia siliqua.
The endophytic fungus Penicillium citrinum was isolated from a fresh stem of the Moroccan plant Ceratonia siliqua. Extracts of P. citrinum grown on rice and white bean media yielded five new compounds, namely, citriquinochroman (1), tanzawaic acids G and H (2 and 3), 6-methylcurvulinic acid (4), 8-methoxy-3,5-dimethylisoquinolin-6-ol (5), and one new natural product, 1,2,3,11b-tetrahydroquinola...
متن کاملAntitumor Effects and Related Mechanisms of Penicitrinine A, a Novel Alkaloid with a Unique Spiro Skeleton from the Marine Fungus Penicillium citrinum
Penicitrinine A, a novel alkaloid with a unique spiro skeleton, was isolated from a marine-derived fungus Penicillium citrinum. In this study, the isolation, structure and biosynthetic pathway elucidation of the new compound were described. This new compound showed anti-proliferative activity on multiple tumor types. Among them, the human malignant melanoma cell A-375 was confirmed to be the mo...
متن کاملQuinolactacide, a new quinolone insecticide from Penicillium citrinum Thom F 1539.
By a screening program searching for new pesticides from fungal sources, an insecticidal compound was isolated from Penicillium citrinum F 1539. The compound, named quinolactacide, was novel and showed 88% mortality against green peach aphids (Myzus persicae) at 250 ppm. Its structure was determined by spectroscopic techniques.
متن کاملDihydroisocoumarins from the Mangrove-Derived Fungus Penicillium citrinum
Three new dihydroisocoumarin penicimarins G-I (1-3), together with one known dihydroisocoumarin (4) and three known meroterpenoids (5-7), were obtained from a fungus Penicillium citrinum isolated from the mangrove Bruguiera sexangula var. rhynchopetala collected in the South China Sea. Their structures were elucidated by the detailed analysis of spectroscopic data. The absolute configuration of...
