Antioxidant and antimutagenic effects of the crude foliar extract and the alkaloid brachycerine of Psychotria brachyceras.

Numai utilizatorii înregistrați pot traduce articole

The monoterpene indole alkaloid brachycerine from Psychotria brachyceras has been shown to be induced by UV and to have in vitro antioxidant activity, indicating a possible protective role against the secondary effects of this radiation. In this work, we have studied the antioxidant properties of

Antioxidant and antimutagenic properties of the monoterpene indole alkaloid psychollatine and the crude foliar extract of Psychotria umbellata Vell.

Psychollatine is a monoterpene indole alkaloid produced and accumulated by Psychotria umbellata Vell. (Rubiaceae) leaves in relatively high amounts (approximately 3% of the dry weight). The alkaloid has been shown to display opioid-like analgesic, anxiolytic, antidepressive and antipsychotic

Anticancer and chemosensitizing abilities of cycloviolacin 02 from Viola odorata and psyle cyclotides from Psychotria leptothyrsa.

Cycloviolacin O2 (CyO2), a cyclotide from Viola odorata (Violaceae) has antitumor effects and causes cell death by membrane permeabilization. In the breast cancer line, MCF-7 and its drug resistant subline MCF-7/ADR, the cytotoxic effects of CyO2 (0.2-10 microM) were monitored in the presence and

Antitumor agents. 89. Psychorubrin, a new cytotoxic naphthoquinone from Psychotria rubra and its structure-activity relationships.

A new naphthoquinone, isolated from the alcoholic extract of Psychotria rubra, exhibited significant cytotoxicity in the KB cell assay (ED50 = 3.0 micrograms/mL). Spectral data was used to assign the structure of psychorubrin as 2. Naphthoquinone derivatives 6, 8, 13, and 14 were prepared and

Shoot accumulation kinetics and effects on herbivores of the wound-induced antioxidant indole alkaloid brachycerine of Psychotria brachyceras.

Numai utilizatorii înregistrați pot traduce articole

A major shoot-specific monoterpene indole alkaloid produced by Psychotria brachyceras, brachycerine, is regulated by either wounding or jasmonate application. Highest concentrations of the alkaloid are found in inflorescences, suggesting a defence role. Brachycerine has antimutagenic and antioxidant

Chemical constituents of the new endophytic fungus Mycosphaerella sp. nov. and their anti-parasitic activity.

Numai utilizatorii înregistrați pot traduce articole

Chemical investigation of a new endophytic fungus, Mycosphaerella sp. nov. strain F2140, associated with the foliage of the plant Psychotria horizontalis (Rubiaceae) in Panama, resulted in the isolation of cercosporin (1) and a new cercosporin analog (3) as the major components. The structures of

Early changes in gene expression induced by acute UV exposure in leaves of Psychotria brachyceras, a bioactive alkaloid accumulating plant.

UV-B radiation can damage biomolecules, such as DNA, RNA, and proteins, halting essential cellular processes; this damage is partly due to ROS generation. Plant secondary metabolites may protect against UV-B. Psychotria brachyceras Müll. Arg. (Rubiaceae), a subtropical shrub, produces brachycerine,

Inactivation of cell surface receptors by pheophorbide a, a green pigment isolated from Psychotria acuminata.

Numai utilizatorii înregistrați pot traduce articole

The inhibition of cytokine and monoclonal antibody binding cell surfaces caused by an extract of Psychotria acuminata, a medicinal plant used in the traditional medicine of the people of Belize (Central Africa), was attributed to the presence of pheophorbide a and pyropheophorbide a. Since the
