Descriptions:
Cucurbitacin B (cucB) is a triterpenoid constituent of Cucurbitaceae vegetables and a promising phytochemical for cancer prevention, cucB induces G(2) arrest and apoptosis through a STAT3-independent but ROS-dependent mechanism in SW480 cells.[1]
Cucurbitacin B has antiproliferative effect, can induce apoptosis by inhibition of the JAK/STAT pathway and potentiates antiproliferative effects of gemcitabine on pancreatic cancer cells, may be an effective, new approach for the treatment of ER-, Her2/neu amplified, and p53 mutant breast cancers.[2,3]
Combination of cucurbitacin B at a relatively low concentration with either of the chemotherapeutic agents, docetaxel (DOC) or gemcitabine (GEM) , shows prominent antiproliferative activity against breast cancer cells without increased toxicity, this promising combination should be examined in therapeutic trials of breast cancer.[4]
Cucurbitacin B has anti-cutaneous squamous cell carcinoma (CSCC) activity by inhibiting growth, arresting the cell cycle, and synergistically potentiate the anti-proliferative effect of cisplatin in CSCC.[5]
Cucurbitacin B a selective inhibitor of JAK2/STAT3 signaling, could promote dendritic cells (DCs) differentiation and improve antitumor immunity, also significantly reduce the frequency of imCs in patients with lung cancers and enhance the effect of p53-specific CTL on tumor 16HBE/BPDE cells.[6]
