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

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

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

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

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 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

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,
