Description | Betulin (BE, betulinol, betuline, betulinic alcohol), also known as betulinol, betuline, or betulinic alcohol, is a pentacyclic lupane-type triterpenoid naturally distributed in many plants and displays a broad spectrum of biological and pharmacological properties such as anticancer and chemopreventive activity. Betulin (Trochol), is a sterol regulatory element-binding protein (SREBP) inhibitor with an IC50 of 14.5 μM in K562 cell line. |

In vitro | Betulin significantly inhibits cell viability in cervix carcinoma HeLa cells, hepatoma HepG2 cells, lung adenocarcinoma A549 cells, and breast cancer MCF-7 cells with IC50 values ranging from 10 to 15 mg/mL. While betulin exhibits only moderate anticancer activity in other human cancer cells such as hepatoma SK-HEP-1 cells, prostate carcinoma PC-3, and lung carcinoma NCI-H460, with IC50 values ranging from 20 to 60 mg/mL, it shows minor growth inhibition in human erythroleukemia K562 cells (IC50>100 mg/mL). Betulin does not directly trigger mitochondrial cytochrome c release in isolated mitochondria. Bax and Bak are rapidly translocated to the mitochondria 30 min after betulin treatment[1]. In vitro, Betulin inhibits LPS-induced tumor necrosis factor α (TNF-α) and (interleukin) IL-6 levels and up-regulates the level of IL-10. Also Betulin suppresses the phosphorylation of nuclear factor-kB (NF-kB) p65 protein in LPS-stimulated RAW 264.7 cells[2]. |
In vivo | In vivo, Betulin alleviates LPS-induced acute lung injury. Treatment with Betulin diminishes pro-inflammatory cytokines, myeloperoxidase activity and bacterial loads in lung tissue during gramnegative pneumonia. In HFD-fed apoE−/− mice, betulin administration significantly reduces lesions in en face aortas and aortic sinuses. Furthermore, betulin administration significantly increases ABCA1 expression and suppresses macrophage positive areas in the aortic sinuses. Moreover, betulin administration improves plasma lipid profiles and enhances fecal cholesterol excretion in the mice[3]. |
