Uji Potensi Triterpenoid dari Kulit Batang Waru Jawa (Hibiscus tiliaceus L.) sebagai Kandidat Antiinflamasi pada Mencit (Mus musculus) Model Rheumatoid Arthritis Berbasis in Silico

Waru jawa (Hibiscus tiliaceus L.) is a plant that functions as an anti-inflammatory. Compounds from the waru jawa plant, especially the bark can be grouped into alkaloids, flavonoids, triterpenoids, and steroids. The content of triterpenoids from the waru jawa stem bark was tested for their biochemical activity, so that it is expected that the bark of Javanese waru stems can be used optimally. This study aims to determine the potential of triterpenoids from waru jawa stem bark as anti-inflammatory candidates in mice (Mus musculus) rheumatoid arthritis model in silico-based. Potential analysis of triterpenoids in mice was carried out using the STITCH, which is a database of known and predicted interactions between chemicals and proteins found in living things. Interactions in question are physical and functional associations, the data contained in STITCH comes from computational predictions, transfer of knowledge between organisms, and from interactions collected from other databases. Analysis of the triterpenoid mechanism of waru jawa stem bark against rheumatoid arthritis model mice in silico-based using the bioinformatics application Kegg. Based on the results of the analysis, it can be seen that triterpenoids derived from waru jawa stem bark sources play an important role in reducing inflammation. The triterpenoids target NF-κB, leading to its downregulation. Triterpenoids have been found to have many functions, although their effective concentrations for various cellular effects may vary widely. Depending upon the dose administered, triterpenoids can induce anti-inflammatory, proliferation-arresting, apoptotic effects, cytoprotective, and tumor-differentiating.

Pharmacological and Biochemical evaluation of anti-arthritic activity of Justicia gendarussa extract in FCA induced arthritis in Wistar rats

The present study is carried out to evaluate anti-inflammatory and anti-arthritic potential of Justicia gendarussa. Leaves and stem extracted with ethanol and chloroform. These extract is tested against in-vitro (HRBC membrane stabilization method and Inhibition of protein denaturation method) and in-vivo (Carrageenan induced paw edema model) anti-inflammatory models. To assess the anti-arthritic activity, FCA induced arthritis model is used. Assessment of arthritis is done by paw volume, joint diameter, body weight, biochemical parameters, hematological parameters (Hb, RBC, WBC, ESR). The effect of in-vitro anti-inflammatory model depends on concentration. Both test extract and standard Diclofenac sodium has been shown concentration dependent effect. The maximum anti-inflammatory effect of the test extract achieved at 2000μg/ml. The test (JGLE, JGLC, JGSE) has been shown inhibition of paw edema induced by carrageenan at 50mg/kg body weight. The extract JGLE, JGLC, JGSE at 50mg/kg body weight and 100mg/kg body weight orally showed the significant (P< 0.05) and dose dependent inhibitory effect against FCA induced arthritis model. Diclofenac sodium 20mg/kg body weight orally is used as a standard. JGLE exhibit more significant and most promising anti-arthritic and anti-inflammatory effect than other extracts these effects support the traditional role of J. gendarussa in arthritis and other inflammatory condition.
