Biological Activity
Description: Bruceine B, a potent inhibitor of leukocyte-endothelial cell adhesion, may have anti-inflammatory activity, it can inhibit neutrophil adhesion to lipopolysaccharide-stimulated HUVEC and T cell adhesion to TNF-stimulated HUVEC. Bruceine B exhibits potent anti-malarial activities with high selective toxicities; it also shows strong antitrypanosomal activities with IC(50) values in the range of 2.9-17.8nM. Bruceine B shows strong antiviral activities, with IC(50) values in the range of 3.42-5.66 microM.

Anti-tobacco mosaic virus (TMV) Quassinoids from Brucea javanica (L.) Merr.[Pubmed: 20050684 ]
Two new quassinoids, javanicolide E (1) and javanicolide F (2), along with fifteen known C-20 quassinoids were isolated from the seeds of Brucea javanica (L.) Merr.
METHODS AND RESULTS:
The antitobacco mosaic virus (TMV) activity of these quassinoids was screened by the conventional half-leaf and leaf-disk method along with Western blot analysis. All of the seventeen quassinoids showed potent anti-TMV activity.
CONCLUSIONS:
Among them, eight compounds, brusatol (3), Bruceine B (4), bruceoside B (5), yadanzioside I (6), yadanzioside L (7), bruceine D (8), yadanziolide A (9), and aglycone of yadanziolide D (17), showed strong antiviral activities, with IC(50) values in the range of 3.42-5.66 microM, and were much more effective than the positive control, ningnanmycin (IC(50) = 117.3 microM). The antiviral structure-activity relationships of quassinoids against TMV were also discussed.

In vitro antitrypanosomal activities of quassinoid compounds from the fruits of a medicinal plant, Brucea javanica.[Pubmed: 18986767 ]
The medicinal plant Brucea javanica (L.) Merr. (Simaroubaceae) is widely distributed throughout Asia where its bitter fruits have been used in traditional medicine for various ailments.
METHODS AND RESULTS:
Fifteen C-20 quassinoids were isolated from the fruits of B. javanica and examined for their in vitro antitrypanosomal activities against trypomastigotes of Trypanosoma evansi. Bruceine A, bruceantinol, bruceine C, brusatol, and Bruceine B showed strong antitrypanosomal activities with IC(50) values in the range of 2.9-17.8nM, which compared well with the standard trypanocidal drugs diminazene aceturate (IC(50)=8.8nM) and suramin (IC(50)=43.2nM). However, dehydrobruceine A, dehydroBruceine B, and dehydrobrusatol were about 2100, 900, and 1200 times less active, respectively, than bruceine A, Bruceine B, and brusatol.
CONCLUSIONS:
The relationship of the structure and antitrypanosomal activity of these quassinoid compounds suggested that the presence of a diosphenol moiety in ring A and the nature of the C-15 side chain are important for their activities against T. evansi. This is the first report on the antitrypanosomal activity of isolated quassinoids.

Anti-malarial activities of acylated bruceolide derivatives.[Pubmed: 9871598]

METHODS AND RESULTS:
Several O-acylated derivatives of bruceolide (2) were synthesized and their anti-malarial activities together with selective toxicities were examined.
CONCLUSIONS:
It was found that 3,15-di-O-acetyl-(3c), 3,15-di-O-propionyl-(3d) and 15-O-propionylbruceolide (3b), as well as Bruceine B (3a), exhibited potent anti-malarial activities with high selective toxicities.

Bruceine B, a potent inhibitor of leukocyte-endothelial cell adhesion.[Pubmed: 9187964]
Leukocyte adhesion to vascular endothelial cells is an essential step in the development of inflammatory diseases.
METHODS AND RESULTS:
We have searched for inhibitors of leukocyte-endothelial cell adhesion that could be used as anti-inflammatory drugs and found that Bruceine B (0.2 microgram/ml; 0.44 microM) inhibited human neutrophil or T cell adhesion to tumor necrosis factor-alpha (TNF) stimulated human umbilical vein endothelial cells (HUVEC). The inhibition of neutrophil adhesion to TNF-stimulated HUVEC by Bruceine B was not derived from cytotoxic effects, as determined by measurement of the level of lactate dehydrogenase (LDH) activity in conditioned medium. The effect of Bruceine B on neutrophil adhesion to HUVEC was not seen when the neutrophils were preincubated with Bruceine B. However, inhibitory effects were evident when the HUVEC were preincubated with Bruceine B. Bruceine B also inhibited neutrophil adhesion to lipopolysaccharide-stimulated HUVEC and T cell adhesion to TNF-stimulated HUVEC.
CONCLUSIONS:
These findings suggest that Bruceine B may have anti-inflammatory activity.

One new pregnane glycoside from the seeds of cultivated Brucea javanica.[Pubmed: 21910051 ]

METHODS AND RESULTS:
A new pregnane glycoside, named (20R)-O-(3)-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranosyl-pregn-5-en-3β,20-diol (1), and seven known compounds, brusatol (2), Bruceine B (3), bruceine D (4), yadanziolide A (5), bruceine E (6), yadanzioside G (7), and yadanzioside B (8), were isolated from the cultivated dry seeds of Brucea javanica. The structure of 1 was elucidated on the basis of 1D- and 2D-NMR spectroscopic analyses. Their inhibitory effects on tumor cells were also tested. Compound 1 was slightly active against HL-60, SMMC-7721, A-549, and MCF-7 tumor cells. Compounds 2 and 3 demonstrated significant inhibitory activities against all tested cells.
CONCLUSIONS:
These results indicate that cultivated B. javanica could replace the wild plant as an antitumor plant resource.
