Abstract:
Background: Rheumatoid Arthritis (RA) is an autoimmune, systemic disease mainly affecting
joints. Presently, there is no specific treatment/ drug available for curing RA except few supportive
medicines. Therefore, the focus has been shifted to medicinal plants for the treatment of such diseases.
Choerospondias axillaris commonly known as Lupsi/Lapsi and has been reported to have several
properties for the treatment of various diseases.
Objective: The present study has been conducted to explore the anti-inflammatory effects of Choerospondias
axillaris fruit extract on Synoviocytes (FLS) and Collagen-Induced Arthritis (CIA) rat model.
Methods: Methanolic extract of the Choerospondias axillaris fruit was used for determining phytochemical,
antioxidant and anti-inflammatory properties. Antioxidant activity of Choerospondias axillaris
fruit was determined by free radicals scavenging assays and bioactive compounds were identified
via LC-MS/MS analysis. Anti-inflammatory effect was investigated in RA and Osteo Arthritis (OA)
primary cells and also in Collagen Induced Arthritis (CIA) rat models. Further, the medicinal properties
of anti-inflammatory bioactive compounds were supported by docking studies.
Results: In-vitro and in-vivo studies showed significant decrease in the levels of inflammatory cytokines.
Docking analysis revealed that quercetin inhibits TNF-α having -9.1 kcal/mol binding energy
and 10.13 μM inhibitory constant. Quercetin also inhibits IL-6 having -6.6 kcal/mol binding energy
and 21.9 μM inhibitory constant.
Conclusion: Observed results suggest that the underutilized fruit Choerospondias axillaris can be used
to reduce the inflammation of inflammatory diseases like RA.
