this synthetic prostaglandin analogue is apparently a poor substrate for the enzymes 15-hydroxyprostaglandin dehydrogenase and 13,14-reductase , which are responsible for the rapid metabolic deactivation of endogenous prostaglandins , as no components identified in urine were found to have undergone metabolic attack at the c-15 atom in the cloprostenol molecule .
