Description and Uses
Cucurbitacin B is a tetracyclic triterpenoid that has been shown to have a strong antitumor activity.
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.
