Abstract
Ten compounds, six extracts and five fractions obtained from three Nigerian plants were assayed for their in vitro antitrypanosomal and antileishmanial activities. Each plant was extacted with hexane, ethyl acetate, and methanol. Isolated compounds were characterized and identified based on their NMR chemical shifts and comparison to literature reports. The crude extracts, fractions and isolated compounds were tested against the kinetoplastid parasites: bloodstream forms of Trypanosoma brucei Lister 427WT and the derived multi-drug resistant clone B48, and promastigote forms of Leishmania mexicana cas9/T7 and the derived clone cas9ΔNT1. Column chromatography of the extracts using silica gel yielded ten compounds identified as curzerenone, epi-curzerenone, chloranthene F, isofuranodienone, 8(17)-12E-labdadiene-15, 16-dial and 15-hydroxy-8(17),12E-labdadiene-16-al from Siphonochilus aetiopicus, lupeol, linalolic acid and spinasterone from Calliandra portoricensis, and abruquinone B from Abrus precatorius. The assay results showed that the Siphonochilus aetiopicus and Calliandra portoricensis crude extracts, fractions and compounds displayed moderate activity against the Trypanosoma brucei but showed less activity against Leishmania mexicana. Abrus precatorius crude extract, fraction, and isolated compound exhibited only weak trypanocidal and leishmanicidal activities against both kinetoplastid parasites tested. These findings have provided evidence for the use of Siphonochilus aetiopicus and Calliandra portoricensis in traditional medicine relating to parasitic diseases.
期刊介绍:
Experimental Parasitology emphasizes modern approaches to parasitology, including molecular biology and immunology. The journal features original research papers on the physiological, metabolic, immunologic, biochemical, nutritional, and chemotherapeutic aspects of parasites and host-parasite relationships.
