The invention relates to new quinoline derivatives of the general Formula I ##STR1## (wherein X stands for hydrogen, halogen or lower alkoxy; n is an integer of 1, 2 or 3; R.sup.1 represents hydrogen and R.sup.2 represents hydroxy-lower alkyl or lower alkoxy-lower alkyl or a group of the general formula IV, ##STR2## wherein Z stands for --O--, --S--, --NH-- or --N(lower alkyl)--; the dotted lines represent optional bonds; and m is 0 or 1; or R.sup.1 and R.sup.2 together with the adjacent nitrogen atom, they are attached to, form a 5- or 6-membered heterocyclic group which may optionally contain a further oxygen, nitrogen or sulfur heteroatom and may be optionally substituted), and pharmaceutically acceptable acid addition salts thereof. The new compounds of the present invention exhibit radiosensitizing effect, make hypoxial cells highly sensitive towards radiation and may be used in radiation therapy.
本发明涉及一种新的
喹啉衍
生物,其一般式为I式:##STR1##(其中X代表氢、卤素或低烷氧基;n为1、2或3的整数;R1代表氢,R2代表羟基-低烷基或低烷氧基-低烷基或式IV的一般式中的一组,##STR2##其中Z代表--O--、--S--、--NH--或--N(低烷基)--;虚线表示可选的键;m为0或1;或R1和R2与相邻的氮原子结合形成一个5-或6-成员杂环基团,该基团可以选择性地包含进一步的氧、氮或
硫杂原子,并且可以选择性地被取代),以及其药学上可接受的酸加盐。本发明的新化合物表现出放射敏化作用,使缺氧细胞对辐射高度敏感,可用于放射治疗。
