Cucurbitacin B 是一类高度氧化的四环三萜,具有口服活性。Cucurbitacin B 抑制癌细胞生长、迁移、侵袭和周期阻滞,但是促进细胞凋亡(apoptosis)。 Cucurbitacin B 具有抗癌、抗炎、抗氧化、抗病毒、降血糖、保肝、神经保护等功效。
Cucurbitacin B belongs to a class of highly oxidized tetracyclic triterpenoids and is oral active. Cucurbitacin B inhibits tumor cell growth, migration and invasion and cycle arrest, but induces cell apoptosis. Cucurbitacin B has potent anti-inflammatory, antioxidant, antiviral, hypoglycemic, hepatoprotective, neuroprotective activity
Application:
Cucurbitacin B hydrate has been used:
as a signal transducer and activator of transcription 3 (stat3) inhibitor to determine its effect on the expression of human lysosomal acid lipase (hLAL) in myeloid-derived suppressor cells (MDSCs).
as an ecdysone receptor (EcR) antagonist injection to lower the levels of 20-hydoxyecdysone (20E) signaling in butterflies.
to determine its effect on the cell viability of pancreatic cancer cell lines.

生化机理
Cucurbitacin B also exhibits anti-cancer activity by inhibiting telomerase and c-Myc in breast cancer. It also exhibits anti- artherosclerotic activity. Cucurbitacin B also possesses anti-inflammatory and anti-microbial activity.
Cucurbitacin B is a triterpenoid constituent of Cucurbitaceae plant species. Cucurbitacin B inhibits proliferation in a wide variety of tumor cell lines (IC50 15-30 nM) by inducing apoptosis and inducing cell cycle arrest at G2/M phase. Although the mechanism of action is unclear, Cucurbitacin B inhibits STAT 3 phosphorylation and expression levels and has been shown to block JAK2 activity. Curcubitacin B also inhibits the transcriptional activity of HIF1a and Nf-KB. Curcubitacin B is structurally similar to the JAK inhibitor Curcubitacin I.
