Abstract
CONTEXT
Justicia gendarussa Burm (Acanthaceae) is a plant used to treat inflammatory diseases such as rheumatoid arthritis. However, the mechanism involved in the anti-inflammatory properties of this plant has not been studied well.
OBJECTIVE
The in vitro anti-inflammatory activities of ethanol extract of Justicia gendarussa leaves (J-01) are studied here for the first time.
MATERIALS AND METHODS
The ethanol extract, J-01 was prepared from the leaves of Justicia gendarussa. The inhibitory effect of J-01 in nitric oxide (NO) production, inducible nitric oxide synthase (iNOS) and matrix metalloproteinase-9 (MMP-9) gene expressions were studied in lipopolysaccharide (LPS) stimulated macrophage cell line RAW 264.7.
RESULTS
J-01 in a concentration dependent manner (200-50 μg/mL) attenuated NO production from macrophage stimulated with LPS (1 μg/mL). Further, J-01 significantly suppressed iNOS mRNA expression in these cells. J-01 has also downregulated the MMP-9 gene expression in LPS stimulated macrophage.
DISCUSSION AND CONCLUSION
The modulatory function of J-01 in inhibiting NO, iNOS, and MMP-9 as obtained from the present in vitro studies provide first scientific evidence to support the anti-inflammatory properties of Justicia gendarussa. This plant may have potential use in the management of inflammatory conditions such as arthritis.
