The invention relates to compounds of formula (I), R.sub.1 and R.sub.2, each independently of the other, are selected from lower alkyl that is unsubstituted or substituted by one or more fluorine atoms which are not linked to the carbon atom of R.sub.1 or R.sub.2 bonding the nitrogen; from lower alkenyl wherein the double bond does not originate from the carbon atom that is bonded to a nitrogen bonding R.sub.1 or R.sub.2 ; from lower alkynyl wherein the triple bond does not originate from the carbon atom that is bonded to a nitrogen bonding R.sub.1 or R.sub.2 ; from cycloalkyl; and from cycloalkyl-lower alkyl; with the proviso that not more than one of the two radicals R.sub.1 and R.sub.2 is methyl; or salts thereof. The mentioned compounds are pharmacologically active against disorders that are responsive to a recuction in intracellular polyamines, such as tumours or protozoal diseases.
本发明涉及式(I)的化合物,其中R.sub.1和R.sub.2各自独立地选择自未取代或取代一个或多个氟原子的低烷基,所述氟原子未连接到与R.sub.1或R.sub.2键合的氮原子的碳原子;自低烯基,其中双键不起源于与键合R.sub.1或R.sub.2的氮原子键合的碳原子;自低炔基,其中三键不起源于与键合R.sub.1或R.sub.2的氮原子键合的碳原子;自环烷基;以及自环烷基-低烷基;但两个基团R.sub.1和R.sub.2中不超过一个是甲基;或其盐。所述化合物在对响应于细胞内多胺减少的紊乱,例如肿瘤或原虫病,具有药理活性。
