Described are compounds of formula I ##STR1## wherein R.sub.1 is hydrogen or hydroxy; R.sub.2, R.sub.2 ' and R.sub.2 " are each independently of the others hydrogen or a substituent other than hydrogen; either R.sub.3 is hydrogen or a substituent other than hydrogen and R.sub.4 is hydrogen or lower alkyl, or R.sub.3 and R.sub.4 together form a divalent radical of the formula --(CH.sub.2).sub.n -- wherein n is 2 or 3; R.sub.5 and R.sub.6 are each independently of the other hydrogen, alkyl or aryl; and either R.sub.7 and R.sub.8 are each hydrogen, or R.sub.7 and R.sub.8 together form a bond; tautomers thereof, provided that at least one tautomerisable group is present; and salts thereof. The compounds inhibit the enzyme S-adenosylmethionine decarboxylase and are suitable, for example, for the treatment of tumours and protozoal infections.
