enzyme CYP101B1, fromNovosphingobiumaromaticivoransDSM12444, binds norisoprenoids more tightly than monoterpenoids and oxidized these substrates with high regioselectivity. Ionols bound less tightly to CYP101B1 than ionones, but the levels of product formation remained high and the selectivity of oxidation was similar to that observed for the parent norisoprenoid. The structurally related sesquiterpene
A cycloalkane derivative represented by the formula (I): ##STR1## wherein A, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, Z, and n are as defined in the specification. The compounds of formula (I) exhibit activities against peptic ulcers and are useful as therapeutic and prophylactic agents for peptic ulcers.
