The disclosure describes new 4-aminoquinoline derivatives of general formula ##SPC1## And their acid addition salts, where X is a halogen atom or a trifluoromethyl group, Z is a hydrogen atom or a defined substituent, R is group of the formula --R.sub.3 N--A--NR.sub.1 R.sub.2 (II), ##SPC2## where A in formula II is a chain of 1 to 5 methylene groups which may be substituted with alkyl, the ring in formula IIIa and IIIb is a piperidine or pyrrolidine ring that may be substituted with alkyl and R.sub.1, R.sub.2 and R.sub.3 represent hydrogen or certain defined substituents. The new 4-aminoquinoline derivatives show anti-malarial activity and, in some cases, show one or more of the following activities:- anti-inflammatory activity, anti-hypertensive activity, anti-trichomonal activity, inhibition of blood platelet aggregation, anti-ulcer activity and activity against allergic asthma. Compounds where --COR is in the o-position with respect to the 7-(halo or trifluoromethyl)-4-quinolylamino group and R is di(lower alkyl)aminopiperidino or --NR.sup.10 R.sup.11 where R.sup.10 is hydrogen or lower alkyl and R.sup.11 is di(lower alkyl)amino(lower alkyl) or 1-(lower alkyl)piperidyl show anti-inflammatory activity.
该披露描述了一种新的4-氨基喹啉衍生物的一般式为##SPC1##及其酸盐,其中X是卤素原子或三氟甲基基团,Z是氢原子或定义的取代基,R是--R.sub.3 N--A--NR.sub.1 R.sub.2(II)的一组,##SPC2##式中的A是1至5个亚甲基基团链,可能被烷基取代,式IIIa和IIIb中的环是可能被烷基取代的哌啶或吡咯烷环,R.sub.1、R.sub.2和R.sub.3代表氢或特定定义的取代基。新的4-氨基喹啉衍生物显示抗疟疾活性,并且在某些情况下,显示以下活性之一或多种:抗炎活性,抗高血压活性,抗滴虫活性,抑制血小板聚集,抗溃疡活性以及抗过敏哮喘活性。在与7-(卤素或三氟甲基)-4-喹啉基氨基基团相对的o-位置上,--COR为二(低烷基)氨基哌啶基团或--NR.sup.10 R.sup.11,其中R.sup.10是氢或低烷基,R.sup.11是二(低烷基)氨基(低烷基)或1-(低烷基)哌啶基团,显示抗炎活性。
