| Nat Prod Res. 2011 Oct;25(17):1621-8. | | Biologically active constituents of Aglaia erythrosperma.[Pubmed: 22011221] |
METHODS AND RESULTS:
From the fruits and leaves of Aglaia erythrosperma (Meliaceae), 10 chemical constituents were isolated and identified, i.e. the dammarane triterpenoids Cabraleadiol (1), cabraleahydroxylactone (2), ethyl eichlerianoate (3), eichlerialactone (4), aglinin A (5), cabralealactone (6), the aglaialactone 5,6-desmethylenedioxy-5-methoxy-aglalactone (7), the flavagline 4'-demethoxy-3',4'-methylenedioxy-methyl rocaglate (8) and two coumarins: scoparone and scopoletin.
CONCLUSIONS:
Flavagline 8 exhibited antimalarial activity with an IC(50) value of 7.30 µg mL(-1) and was strongly cytotoxic against small cell lung cancer (NCI-H187), epidermoid carcinoma (KB) and breast cancer (BC) cell lines, with IC(50) values of 2.17, 2.10 and 0.11 µg mL(-1), respectively. | | Z Naturforsch C. 2011 May-Jun;66(5-6):245-50. | | Effect of triterpenoids and limonoids isolated from Cabralea canjerana and Carapa guianensis (Meliaceae) against Spodoptera frugiperda (J. E. Smith).[Pubmed: 21812341 ] |
METHODS AND RESULTS:
The activities of two triterpenoids, ocotillone and Cabraleadiol, and four limonoids, methyl angolensate, 3-beta-deacetylfissinolide, 7-deacetoxy-7-oxogedunin, and beta-photogedunin, isolated from arillus of Carapa guianensis and fruits and seeds of Cabralea canjerana (Meliaceae), were evaluated against the fall armyworm Spodoptera frugiperda. Gedunin was used as a positive control.
7-Deacetoxy-7-oxogedunin and beta-photogedunin reduced the pupal weight as occurred with gedunin.
CONCLUSIONS:
Cabraleadiol, 3-beta-deacetylfissinolide, and 7-deacetoxy-7-oxogedunin prolonged the larval phase similar to the control (gedunin) of approximately 1.2 days at 50.0 mg kg(-1). The highest insecticidal activity was obtained for beta-photogedunin. | | Arch Pharm Res. 2008 Jan;31(1):21-7. | | A new sesquiterpene and other terpenoid constituents of Chisocheton penduliflorus.[Pubmed: 18277603] |
METHODS AND RESULTS:
A new aromadendrane sesquiterpene, allo-aromadendrane-10alpha, 14-diol (3), was isolated from Chisocheton penduliflorus (Meliaceae), along with two known sesquiterpenes: allo-aromadendrane-10beta, 14-diol (2) and allo-aromadendrane-10beta, 13, 14-triol (7). Six dammarane triterpenoids, including Cabraleadiol (1), eichlerialactone (4), cabraleahydroxylactone (5), cabralealactone (6), hollongdione (8) and dammaradienone (9), the coumarins scoparone and scopoletin, and vanillic acid were also isolated from the wood and leaves of this plant.
CONCLUSIONS:
Compounds 1-7 displayed antimycobacterial activity against Mycobacterium tuberculosis. Compounds 1, 4, 5 and 6 were weakly cytotoxic to a breast cancer (BC) cell line; whereas, compound 6 was moderately active against a small-cell lung cancer (NCI-H187) cell line. |
