  Quinolones of the formula I ##STR1## in which the dotted line between positions 2 and 3 of the quinolone ring represents an optional bond; R is hydrogen or lower alkyl; R.sub.1 is lower alkyl; and R.sub.2, R.sub.3 and R.sub.4, which may be the same or different, are hydrogen, halo, lower alkyl, lower alkoxy, lower alkylthio, lower alkylsulphinyl, lower alkylsulphonyl, trifluoromethyl, cyano, fluorinated lower alkoxy, phenyl optionally substituted by one or two substituents selected from lower alkyl, lower alkoxy, lower alkylthio, halo and trifluoromethyl, the group --OAr or the group --S(O).sub.n Ar in which Ar is phenyl optionally substituted by one or two substituents selected from lower alkyl, lower alkoxy, lower alkylthio, halo and trifluoromethyl and n is 0, 1 or 2, or the group --NR.sub.5 R.sub.6 or the N-oxide thereof in which R.sub.5 and R.sub.6, which may be the same or different, are lower alkyl or, together with the nitrogen atom to which they are attached, form a 5-7 membered ring optionally containing an additional hetero atom selected from oxygen, nitrogen and sulphur have utility as antihypertensive agents. Novel quinolones are those of the above-defined formula I, provided that (a) when the optional 2,3-bond is present R.sub.1 is methyl and R is hydrogen, at least one of R.sub.2, R.sub.3 and R.sub.4 is other than hydrogen and (b) when the optional 2,3-bond is present, R is lower alkyl and R.sub.3 and R.sub.4 are hydrogen, R.sub.2 is other than hydrogen or lower alkoxy. Pharmaceutical compositions comprising a novel quinolone of the above formula I together with a pharmaceutically acceptable carrier are described and claimed. Processes for preparing the novel quinolones are also described.

  式I中的喹诺酮化合物为：##STR1## 其中喹诺环的2和3位之间的虚线表示可选键；R为氢或低碳基；R.sub.1为低碳基；R.sub.2、R.sub.3和R.sub.4可相同可不同，为氢、卤素、低碳基、低氧基、低硫基、低硫酰基、低硫酸基、三氟甲基、氰基、氟化低氧基、苯基（可选用一个或两个来自低碳基、低氧基、低硫基、卤素和三氟甲基的取代基）、--OAr或--S（O）.sub.nAr（其中Ar为苯基，可选用一个或两个来自低碳基、低氧基、低硫基、卤素和三氟甲基的取代基，n为0、1或2）或--NR.sub.5R.sub.6或其N-氧化物，其中R.sub.5和R.sub.6可相同可不同，为低碳基或与它们所连接的氮原子一起形成一个5-7成员环，该环可选包含一个来自氧、氮和硫的额外杂原子。该类化合物具有降压作用。新型喹诺酮化合物的定义如下：在可选的2,3-键存在时，R.sub.1为甲基且R为氢，R.sub.2、R.sub.3和R.sub.4中至少有一个不为氢；在可选的2,3-键存在时，R为低碳基，R.sub.3和R.sub.4为氢，R.sub.2不为氢或低氧基。本文还描述了含有上述式I中新型喹诺酮化合物和药学上可接受的载体的制药组合物，并对制备新型喹诺酮化合物的过程进行了描述。
