8-azadecalin derivatives. Strong inhibitory activity was observed for those compounds having carbon chains around C12. Interestingly, the amide compounds (not the carbocationic intermediate) exhibited remarkably strong inhibition toward the liver cyclase, whereas they had an insignificant effect on the yeast cyclase (about 10(2)-fold less active). The yeast cyclase needed the amine functionality (carbocationic

cycloeucalenol obtusifoliol isomerase, respectively. In accordance with the ‘transitionstateanalogues’ theory, this analogue of a high energy intermediate was found to be a very potent and specific inhibitor of the two enzymatic reactions both in vitro and in vivo .
