This study evaluates the pharmacological effects of iridoid glucoside loganic acid, a plant constituent with diverse properties, based on literature, and explores the underlying cellular mechanisms for treating several ailments. Data were collected from reliable electronic databases, including PubMed, Scopus, Web of Science, and Google Scholar, etc. The results demonstrated the anti-inflammatory, anti-oxidant, and other protective effects of loganic acid on metabolic diseases and disorders such as atherosclerosis, diabetes, and obesity, in addition to its osteoprotective and anticancer properties. The antioxidant activity of loganic acid demonstrates its capacity to protect cells from oxidative damage and mitigates inflammation by reducing the activity of inflammatory cytokines involving TNF-α and IL-6, substantially upregulating the expression of PPAR-γ/α, and decreasing the clinical signs of inflammation-related conditions related to hypertriglyceridemia and atherosclerosis. Meanwhile, loganic acid inhibits bone loss, exhibits osteoprotective properties by increasing mRNA expression levels of bone synthesizing genes such as Alpl, Bglap, and Sp7, and significantly increases osteoblastic proliferation in preosteoblast cells. Loganic acid is an anti-metastatic drug that reduces MnSOD expression, inhibits EMT and metastasis, and prevents cellular migration, proliferation, and invasion in hepatocellular carcinoma cells. However, additional clinical trials are required to assess its safety, efficacy, and human dose., (© 2024 Wiley-VHCA AG, Zurich, Switzerland.)

Rosavin is an alkylbenzene diglycoside primarily found in Rhodiola rosea (L.), demonstrating various pharmacological properties in a number of preclinical test systems. This study focuses on evaluating the pharmacological effects of rosavin and the underlying molecular mechanisms based on different preclinical and non-clinical investigations. The findings revealed that rosavin has anti-microbial, antioxidant, and different protective effects, including neuroprotective effects against various neurodegenerative ailments such as mild cognitive disorders, neuropathic pain, depression, and stress, as well as gastroprotective, osteoprotective, pulmoprotective, and hepatoprotective activities. This protective effect of rosavin is due to its capability to diminish inflammation and oxidative stress. The compound also manifested anticancer properties against various cancer via exerting cytotoxicity, apoptotic cell death, arresting the different phases (G 0 /G 1 ) of the cancerous cell cycle, inhibiting migration, and invading other organs. Rosavin also regulated MAPK/ERK signaling pathways to exert suppressing effect of cancer cell. However, because of its high-water solubility, which lowers its permeability, the phytochemical has low oral bioavailability. The compound's relevant drug likeness was evaluated by the in silico ADME, revealing appropriate drug likeness. We suggest more extensive investigation and clinical studies to determine safety, efficacy, and human dose to establish the compound as a reliable therapeutic agent., (© 2024 Wiley-VHCA AG, Zurich, Switzerland.)
