Based on 1 publication(s) in Google Scholar
Alisol A 24-acetate (Alisol A monoacetate) is an orally active derivative of protostane-type tetracyclic triterpenoid. Alisol A 24-acetate upregulates the expression of adiponectin, AMPKα, CPT1, and ACOX1; downregulates the expression of SREBP-1c, ACC, FAS, Bcl-2, Bcl-xl, PPAR-γ, perilipin A, and NFATc1; inhibits the activity of PI3K/Akt/mTOR and HMGR; and activates the PKA and ERK signaling pathways. Alisol A 24-acetate regulates cell apoptosis (apoptosis), autophagy (Autophagy, hepatic lipid accumulation, inflammatory response, neuroprotection, MRSA membrane integrity, and osteoclast differentiation. Alisol A 24-acetate can be used in research related to non-alcoholic fatty liver disease, nephrotoxicity, obesity, global cerebral ischemia-reperfusion injury, bacterial infection, and osteoporosis.

Alisol A 24-acetate (2.5-100 μM; 24 h) reduces HepG2 cell viability in a dose-dependent manner, with significant cytotoxicity observed at concentrations above 10 μM after 24 h of incubation[1].
Alisol A 24-acetate (10 μM; 24 h) improved free fatty acid-induced lipid accumulation and inflammatory response in HepG2 cells, reduced lipid droplet formation, positive lipids, and intracellular triglyceride levels, decreased TNF-α and IL-6 levels in cell supernatant, and upregulated adiponectin protein and mRNA expression. This substance activated AMPKα phosphorylation and increased AMPK mRNA expression, downregulated SREBP-1c, ACC, and FAS at the transcriptional and protein levels, and upregulated CPT1 and ACOX1, without significantly affecting PPARα expression[1].
Alisol A 24-acetate (compound 24A) (3-768 μM; 24 h) reduces HK-2 cell viability in a concentration-dependent manner, with 6 μM yielding a cell viability of 96.20% for use in follow-up assays[2].
Alisol A 24-acetate (6 μM; 24 h) downregulated the protein and mRNA expression of Bcl-2 and Bcl-xl to induce apoptosis in HK-2 cells, and upregulated the protein and mRNA expression of Kim-1, Clusterin, and TFF-3 to induce nephrotoxicity. Simultaneously, it induced autophagy in HK-2 cells by increasing the LC3II/LC3I ratio, upregulating the protein and mRNA levels of Beclin-1 and LC3, and inhibiting the PI3K/Akt/mTOR pathway[2].
Alisol A 24-acetate (6 μM; 48 h)-induced autophagy mediates apoptosis and nephrotoxicity in HK-2 cells, as co-incubation with autophagy inhibitor 3-MA reverses cell viability loss, reduces LC3II/LC3I ratio, increases anti-apoptotic Bcl-2, and decreases nephrotoxicity biomarker Kim-1[2].
Alisol A 24-acetate (AA-24-a) (10-50 μM; 24-72 h) can improve the survival rate of fully differentiated 3T3-L1 adipocytes and significantly stimulate basal lipolysis in fully differentiated 3T3-L1 adipocytes[3].
Alisol A 24-acetate (50 μM; 12 h) alters lipolysis-related gene expression in fully differentiated 3T3-L1 adipocytes, increasing ATGL mRNA levels and decreasing HSL, PPARγ, and perilipin A mRNA levels[3].
Alisol A 24-acetate (30-50 μM; 24-36 h) increases ATGL protein expression and HSL phosphorylation at Ser660 in fully differentiated 3T3-L1 adipocytes, while also activating ERK and reducing PPARγ and perilipin A protein levels[3].
Alisol A 24-acetate-induced lipolysis in fully differentiated 3T3-L1 adipocytes is partly mediated by PKA-induced phosphorylation of HSL at Ser660[3].
Alisol A 24-acetate (30-50 μM; 20 h) can induce lipolysis in fully differentiated 3T3-L1 adipocytes. This effect is mediated by ERK pathway activation, which further downregulates PPARγ and perilipin A expression. Pretreatment with PD98059 (HY-12028) can reduce glycerol release and reverse the above molecular changes[3].
Alisol A 24-acetate (24A) can reduce the levels of inflammatory factors TNF−α, IL-1β, IL-6, and IL-8 in HepG2 cells; it has a protective effect on tight junctions of brain microvascular endothelial cells damaged by oxygen and glucose deprivation; and it strongly inhibits MRSA HMG[4].

Alisol A 24-acetate (10 μM; 1 h pre-incubation, 1-3 days RANKL stimulation) significantly inhibits RANKL-induced NFATc1 protein expression in mouse bone marrow-derived macrophages over 3 days of stimulation[6].
