Quinocitrinines A and B, new quinoline alkaloids from Penicillium citrinum Thom 1910, a permafrost fungus.
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 occ...
متن کاملQuinolactacins A1 and A2, new acetylcholinesterase inhibitors from Penicillium citrinum.
Alzheimer disease is a neurodegenerative disorder that is the most commoncause of dementia amongthe elderly. The neurophathological evidences have demonstrated that cholinergic functions declined in the basal forebrain and cortex in senile dementia of the Alzheimer type1>2). Accordingly, enhancement of cholinergic neurotransmission have been considered as one potential therapeutic approach agai...
متن کاملCitrinolactones A, B and C, and Sclerotinin C, plant growth regulators from Penicillium citrinum.
New plant growth regulators, named citrinolactones A (1), B (2) and C (3) and sclerotinin C (4), were isolated from Penicillium citrinum and their structures established by spectroscopic methods including 2D NMR. Compounds 1 and 4 increased root growth in proportion to their concentration from 3 to 300 mg/l. In contrast, 2 completely inhibited root growth at a concentration of 300 mg/l and 3 di...
متن کاملEndo and exoglucanases produced by Penicillium citrinum isolated from Amazon
Background Cellulolytic enzymes (glucohidrolases EC 3.2.1.-) are biocatalizators highly specific. They act in synergy to hydrolyze b-1,4 bonds between monosaccharide units of D-glucose in the cellulose chain releasing its constituents. Cellulases are categorized according to the place they act in the cellulosic fiber. Endoglucanases start hydrolysis, exoglucanases act in the reduced terminal pr...
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.
