Cucurbitacin B
Together wth other cucurbitacins, is responsible for the bitter taste and toxic props. of spoilt cucumbers. Cucurbitacin B is found in many foods, some of which are muskmelon, bitter gourd, green vegetables, and cucumber. Cucurbitacin B is found in bitter gourd. Together wth other cucurbitacins, is responsible for the bitter taste and toxic properties of spoilt cucumber Cucurbitacin B is a cucurbitacin in which a lanostane skeleton is multi-substituted with hydroxy, methyl and oxo substituents, with unsaturation at positions 5 and 23; a hydroxy function at C-25 is acetylated. It is a cucurbitacin, a secondary alpha-hydroxy ketone and a tertiary alpha-hydroxy ketone. It derives from a hydride of a lanostane. Cucurbitacin B is a natural product found in Begonia plebeja, Trichosanthes miyagii, and other organisms with data available. 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[1][2][3][4][5].
