New benzimidazole derivatives of the general formula (I) ##SPC1## and acid addition salts thereof, wherein R.sub.1 and R.sub.2 each represent hydrogen or methyl, R.sub.5 and R.sub.6 form together a valence bond and at the same time R.sub.3 and R.sub.4 form together a group of the general formula (II), ##EQU1## wherein n is equal to zero or one, or R.sub.4, R.sub.5 and R.sub.6 form together a group of the formula (III) ##EQU2## and at the same time R.sub.3 stands for benzyl group, were prepared by reacting a compound of the general formula (IV), ##SPC2## wherein R.sub.7 stands for hydrogen or benzyl group and R.sub.1, R.sub.2 and n each have the same meanings as defined above, or an acid addition salt thereof with epichlorohydrine optionally in the presence of a base. The new compounds of the general formula (I) and their acid addition salts inhibit the reproduction of viruses and can be used in therapy as antiviral agents.
通式(I)的新苯并咪唑衍生物及其酸加成盐,其中R1和R2分别代表氢或甲基,R5和R6结合成一个价键,同时R3和R4结合成通式(II)的一个基团,其中n等于零或一,或者R4、R5和R6结合成通式(III)的一个基团,同时R3代表苄基。通过将通式(IV)的化合物与环氧氯丙烷在碱的存在下反应,其中R7代表氢或苄基,R1、R2和n的含义如上定义,或其酸加成盐,制备了通式(I)的新化合物。通式(I)的新化合物及其酸加成盐抑制病毒的复制,可用于治疗作为抗病毒剂。
