Compounds of the formulas ##STR1## and ##STR2## wherein A is --CH.sub.2 -- or --CH(OH)--, R.sub.1 is hydrogen, halogen or, when R.sub.2 and R.sub.3 are other than both hydrogen, also methyl, R.sub.2 is hydrogen, halogen, cyano, nitro, amino or (alkanoyl of 1 to 4 carbon atoms)-amino, R.sub.3 is hydrogen or halogen, Provided, however, that at least one of R.sub.1, R.sub.2 and R.sub.3 is other than hydrogen, and R.sub.4 is hydrogen or alkyl of 1 to 4 carbon atoms, and non-toxic salts of the free acids (R.sub.4 = H) formed with inorganic or organic bases; the compounds as well as their salts are useful as antiphlogistics and antiproliferatives.
化合物的公式为##STR1##和##STR2##,其中A为--CH.sub.2--或--CH(OH)--,R.sub.1为氢,卤素或当R.sub.2和R.sub.3不同时也为甲基,R.sub.2为氢,卤素,氰基,硝基,氨基或(1至4个碳原子的酰基)-氨基,R.sub.3为氢或卤素,但至少其中一个R.sub.1,R.sub.2和R.sub.3不是氢,R.sub.4为氢或1至4个碳原子的烷基,以及与无机或有机碱形成的自由酸(R.sub.4 = H)的无毒盐;这些化合物及其盐可用作抗炎和抗增殖剂。
