Arjunolic acid acts as a free radical scavenger in cell-free systems by scavenging superoxide radicals, hydroxyl radicals, hydrogen peroxide, and nitric oxide radicals[2]. Arjunolic acid (0.5-30 μg/spot) inhibits the growth of *Bacillus subtilis*, *Escherichia coli* and *Shigella sonnei* in an in vitro spot assay[2]. Arjunolic acid (20 μg/mL) inhibits the growth of *Cryptococcus neoformans* with an IC50 of 20 μg/mL in in vitro antifungal assays[2]. Arjunolic acid induces 66% cell death in Dalton cells and 70% cell death in Ehrlich cells via membrane damage[2]. Arjunolic acid inhibits 12-O-tetradecanoylphorbol-13-acetate-induced Epstein-Barr virus-EA activation in Raji cells[2]. Arjunolic acid (200 μM) protects mouse hepatocytes against cadmium-induced oxidative stress and apoptotic death by reducing reactive oxygen species, inhibiting NF-κB activation, and blocking both endogenous and exogenous apoptotic signaling pathways; it also prevents sodium fluoride-induced oxidative stress and necrotic death in mouse hepatocytes[2]. Arjunolic acid (5-20 μM; 1 h) promotes the polarization of LPS (HY-D1056)-stimulated BV2 cells from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype, upregulates the expression and activity of SIRT1 in cells, activates AMPK and inhibits the expression of Notch1[3]. Arjunolic acid (20-200 μM; 2-24 h) directly binds to and stabilizes the SIRT1 protein in BV2 mouse microglial cell lysates[3]. Arjunolic acid (5-40 μM; 48 h) protects LPS-induced colonic organoids from wild-type mice by reducing epithelial cell apoptosis and enhancing organoid viability[4]. Arjunolic acid (1-100 μg/mL; 24 h) reduces the viability of Saos-2 and U-2OS osteosarcoma cells in a concentration-dependent manner[5]. M2/M0 macrophages pretreated with arjunolic acid (50 μg/mL; 24 h pre-treatment of M2/M0 macrophages) inhibit the proliferation, migration and invasion of Saos-2 and U-2OS osteosarcoma cells, induce G1-phase cell cycle arrest, and promote apoptosis of these cells[5]. Arjunolic acid (50 μg/mL) promotes the polarization of M0 macrophages toward the pro-inflammatory M1 phenotype[5]. Arjunolic acid (50 μg/mL; 24 h) inhibits osteosarcoma cell-induced polarization of M0 macrophages toward the M2 phenotype and promotes their polarization toward the M1 phenotype[5]. Arjunolic acid (50 μg/mL; 24 h) inhibits Wnt3a-mediated polarization of M0 macrophages toward the M2 phenotype and promotes their polarization toward the M1 phenotype[5]. Arjunolic acid (5-10 μM; 24 h, co-treated with H2O2) significantly enhances the viability of ARPE-19 cells damaged by H2O2[6]. Arjunolic acid (5-10 μM; 24 h, co-treated with H2O2) dose-dependently reduces H2O2-induced early and total apoptosis levels in ARPE-19 cells, and restores the expression of apoptosis-related proteins to normal levels[6]. Arjunolic acid (5-10 μM; 24 h, co-treated with H2O2) alleviates oxidative stress in ARPE-19 cells by reducing reactive oxygen species (ROS) and malondialdehyde (MDA) levels, increasing superoxide dismutase (SOD) levels, and upregulating heme oxygenase-1 (HO-1) at the dose of 10 μM[6]. Arjunolic acid (5-10 μM; 24 h, co-treated with H2O2) inhibits H2O2-induced autophagy in ARPE-19 cells via activation of the AMPK/mTOR pathway[6].

Arjunolic acid (50-100 mg/kg; single dose) exerts dose-dependent mast cell-stabilizing activity, reducing compound 48/80-induced rat mast cell degranulation to 42% at a dose of 50 mg/kg and to 33% at 100 mg/kg[2].

Arjunolic acid (1% topical ointment) promotes skin wound healing in rats and achieves complete epithelialization on day 20[2]. Arjunolic acid (10-40 mg/kg; i.g.; daily; 7 days) significantly ameliorates LPS-induced depressive-like behaviors in male C57BL/6 mice by promoting M2 polarization of microglia, increasing BDNF and 5-HT levels in the hippocampus, and activating the SIRT1/AMPK/Notch1 signaling pathway[3]. Arjunolic acid (15-60 mg/kg; p.o.; daily; 28 days) alleviates spontaneous Crohn's disease-like colitis in Il-10-/- mice by improving intestinal barrier function, inhibiting intestinal epithelial cell apoptosis (via downregulating the TLR4/MyD88 pathway), and restoring the composition of beneficial intestinal flora and the production of short-chain fatty acids[4]. Arjunolic acid (100 mg/kg; p.o.; once daily; 21 days) inhibits the progression and metastasis of osteosarcoma in nude mice by downregulating Wnt3a, reducing tumor proliferation, promoting tumor cell apoptosis, and shifting the polarization of tumor-associated macrophages from the pro-tumor M2 phenotype to the anti-tumor M1 phenotype[5]. Oral administration of arjunolic acid (10-30 mg/kg; p.o.; once daily for 10 weeks) improves Streptozotocin (HY-13753)-induced diabetic retinopathy in rats by reducing fasting blood glucose, increasing body weight, preserving retinal structure, inhibiting retinal cell apoptosis and inflammatory responses, upregulating HO-1, and activating the AMPK/mTOR-regulated autophagy pathway[6]. Arjunolic acid (1.0-2.0 mg/kg; p.o.; daily; 4 weeks) reverses Fluoxetine (HY-B0102)-induced testicular dysfunction in male Wistar rats by inhibiting oxidative inflammatory stress and apoptosis, with the anti-inflammatory efficacy of the 2.0 mg/kg oral dose being superior to that of the 1.0 mg/kg dose[7].
