Cucurbitane is a chemical compound with formula C30H54 (CAS number 65441-59-0). It is a polycyclic hydrocarbon, specifically a triterpene. It is an isomer of lanostane (specifically 19(10→9β)abeo-lanostane), from which it differs by the formal shift of a methyl group (carbon number 19) from the 10 to the 9β position in the standard steroid numbering scheme.[1][2]

The name is applied to two stereoisomers, distinguished by the prefixes 5α- and , which differ by the handedness of the bonds at a particular carbon atom (number 5 in the standard steroid numbering scheme).[1]



Natural compounds

Compounds with the basic cucurbitane skeleton are found in many plants, and some are important phytopharmaceuticals,[3] Natural cucurbitane-related compounds include:
