    <description> belongs to the class of organic compounds known as cucurbitacins. These are polycyclic compounds containing the tetracyclic cucurbitane nucleus skeleton, 19-(10-&gt;9b)-abeo-10alanost-5-ene (also known as 9b-methyl-19-nor lanosta-5-ene), with a variety of oxygenation functionalities at different positions.</description>
