Alkylation of phenols IIa-IIc by the action of ω-(N,N-dialkylamino)alkyl chlorides IIIa-IIId in an anhydrous or a two-phase medium (toluene-aqueous potassium hydroxide) gave rise to the dibasic derivatives IV-XI. In the two-phase medium, alkylation of IIa with IIIc produced the basic ether XII as the main product, a decarboxylation product, and compound VII. In biological test compound IV showed the strongest antibacterial effects on four kinds of bacteria, was efficacious in vivo against the viruses of encephalomyocarditis and vaccinia, and induced the formation of interferon to the same extent as Tiloron. The antineoplastic effects of the compounds were weaker than those observed with compound I (Benfluron) administered to animals with experimental, transplantable tumours.
酚的烷基化IIa-IIc通过ω-(N,N-二烷基氨基)烷基氯化物IIIa-IIId在无水或两相介质(甲苯-水合氢氧化钾)的作用下产生了二元衍生物IV-XI。在两相介质中,IIa与IIIc的烷基化产生了主要产物碱性醚XII,一个脱羧产物和化合物VII。在生物测试中,化合物IV对四种细菌表现出最强的抗菌效果,在体内对脑心肌炎病毒和牛痘病毒具有疗效,并诱导干扰素的形成程度与Tiloron相同。这些化合物的抗肿瘤效果弱于用于实验性可移植肿瘤动物的化合物I(Benfluron)观察到的效果。
