Cucurbitacin e is a member of the class of compounds known as cucurbitacins. Cucurbitacins are polycyclic compounds containing the tetracyclic cucurbitane nucleus skeleton, 19-(10->9b)-abeo-10alanost-5-ene (also known as 9b-methyl-19-nor lanosta-5-ene), with a variety of oxygenation functionalities at different positions. Cucurbitacin e is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Cucurbitacin e is a bitter tasting compound found in cucumber, muskmelon, and watermelon, which makes cucurbitacin e a potential biomarker for the consumption of these food products. Cucurbitacin E is a natural compound which from Cucurbitaceae plants. Cucurbitacin E significantly suppresses the activity of the cyclin B1/CDC2 complex. Cucurbitacin E is a natural compound which from Cucurbitaceae plants. Cucurbitacin E significantly suppresses the activity of the cyclin B1/CDC2 complex.
