Cucurbitane is a class of tetracyclic chemical compounds with formula C30H54 (CAS number 65441-59-0). It is a polycyclic hydrocarbon, specifically triterpene. It is also an isomer of lanostane (specifically 19(10→9β)-abeolanostane), 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 5β-, which differ by the handedness of the bonds at a particular carbon atom (number 5 in the standard steroid numbering scheme).[1]

Derivatives

Natural compounds

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