Key research themes
1. What are the phytochemical constituents of Abrus precatorius seeds and how do they relate to its pharmacological or toxicological properties?
This research theme focuses on identifying and characterizing the bioactive compounds present in Abrus precatorius seeds using phytochemical, chromatographic, and spectroscopic methods to understand their contribution to the plant's diverse pharmacological activities and toxicity profile. Understanding the chemical makeup is essential to linking traditional uses, toxicity, and therapeutic potential.
Key finding: This review compiles extensive phytochemical data demonstrating that Abrus precatorius seeds contain alkaloids, flavonoids, phenolic compounds, tannins, steroids, triterpenoids, and glycosides such as abrusosides. These... Read more
Key finding: Three compounds were isolated and structurally characterized from methanolic extracts of Abrus precatorius seeds: (4,6-O-Benzylidene) methyl-alpha D-glucopyranoside, an isoflavone derivative, and 3-Carboxy-1-methyl pyridinium... Read more
Key finding: Although focusing on leaves, this study isolated a novel pterocarpan compound (2,3,4,8-tetramethoxy-6a,11a-dihydro-6H-benzo[4,5]furo[3,2-c]chromene-7,9-diol), highlighting the complexity of Abrus metabolites. The study... Read more
Key finding: Methanolic seed extracts of Abrus precatorius exhibited significant antifungal activity, attributed to phytochemicals absorbing at UV wavelengths (peaks at 238 nm). The study suggests bioactive compounds in the seeds... Read more
Key finding: This study examined chemical changes in Abrus precatorius seeds undergoing detoxification with cow urine and saline via changes in TLC profiles and loss of agglutination activity (abrin). Results confirm that seed processing... Read more
2. What is the toxicological profile and clinical manifestation of Abrus precatorius seed toxicity in humans and animals?
This theme synthesizes research on Abrus precatorius seed toxicity, focusing on the mechanisms, clinical signs, and outcomes of poisoning in humans and livestock, as well as detoxification strategies. Understanding toxicity is critical due to the high fatal potential of seed abrin and its medical and forensic implications.
Key finding: The paper presents a clinical case demonstrating abrin toxicity after ingestion of crushed Abrus seeds for suicide. It details gastrointestinal symptoms, biochemical derangements, and supportive treatment outcomes. It... Read more
Key finding: This comprehensive review covers the dual aspects of therapeutic potential and toxicity of Abrus precatorius seeds, emphasizing that toxic proteins like abrin present serious risks while traditional herbal applications... Read more
Key finding: This study reports that Abrus precatorius poisoning in animals, primarily due to abrin in crushed seeds or needle-like injections, causes local necrosis, severe gastroenteritis, neurological signs, and death. It documents... Read more
Key finding: This investigation demonstrates that detoxification media including cow urine and saline reduce abrin content in seeds, verified by the absence of agglutination activity ex vivo and alterations in chemical fingerprints,... Read more
3. How effective are Abrus precatorius seed extracts as anticancer and antioxidant agents against cervical carcinoma and other malignancies?
This theme addresses studies evaluating the bioactivity of Abrus precatorius seed extracts to inhibit cancer cell proliferation, induce antioxidant effects, and interact with oncogenic receptors, particularly focusing on cervical cancer cell lines. It encompasses biochemical quantification, docking studies, and cellular assays to validate anticancer potential.
Key finding: The study demonstrated that methanolic seed extracts prepared by Soxhlet and maceration had high flavonoid, phenolic, and tannin content, exhibiting strong antioxidant activities and dose-dependent antiproliferative effects... Read more
Key finding: Findings confirmed that seed extracts have differential phytochemical profiles influencing their antioxidant enzyme activities (SOD, catalase, GST) and reduction of oxidative stress markers (MDA) in cervical cancer (HeLa and... Read more
Key finding: This review elucidates that multiple phytochemicals from Abrus precatorius seeds and other parts, including lectins, alkaloids, and flavonoids, target diverse oncogenic pathways to exert anti-cancer and anti-angiogenic... Read more
