Descriptions:
Corosolic acid (CRA), a constituent of banaba leaves, has been reported to have anti-inflammatory and hypoglycemic activities, it can ameliorate hypertension, abnormal lipid metabolism, and oxidative stress as well as the inflammatory state in SHR-cp rats, suggests CRA can be beneficial for preventing atherosclerosis-related diseases.[1]
Corosolic acid significantly inhibits cell viability in both a dose- and a time-dependent manner, induces apoptosis is associated with the activation of caspases via a mitochondrial pathway, suggests it could have strong potentials for clinical application in treating human cervix adenocarcinoma and improving cancer chemotherapy.[2]
Corosolic acid can suppress the M2 polarization of macrophages and tumor cell proliferation by inhibiting both STAT3 and NF-κB activation, thus, it might be a potential new tool for tumor prevention and therapy.[3]
Corosolic acid has antidiabetic effects(especially type 2 diabetes), can improve glucose metabolism by reducing insulin resistance, it inhibits the enzymatic activities of several diabetes-related non-receptor protein tyrosine phosphatases (PTPs) in vitro, such as PTP1B, T-cell-PTP, src homology phosphatase-1 and src homology phosphatase-2.[4,5]
Corosolic acid has antitumor effects in murine sarcoma model through significantly impairing subcutaneous tumor development and lung metastasis and targeting the immunosuppressive activity of myeloid-derived suppressor cells (MDSC), and can enhance the antitumor effects of adriamycin and cisplatin in in vitro.[6]
