The invention relates to new compounds of the general formula (I), ##STR1## wherein R.sup.1 and R.sup.5 each represent a phenyl group, optionally substituted, R.sup.2 stands for hydrogen, formyl group, carboxy group, lower alkoxycarbonyl group, hydroxy-(lower)-alkoxycarbonyl group, or a lower alkyl group, optionally substituted, R.sup.3 and R.sup.4 each represent hydrogen atom or a lower alkyl group, with the proviso that when R.sup.1 and R.sup.5 each represent a phenyl group, R.sup.2 and R.sup.3 may not stand for hydrogen. These compounds possess valuable biological properties, and can be applied primarily as antiphlogistic or diuretic agents.
本发明涉及一般式(I)的新化合物,其中R.sup.1和R.sup.5各代表苯基,可选择性取代,R.sup.2代表氢,甲酰基,羧基,低烷氧羰基基,羟基-(低)-烷氧羰基基或低烷基,可选择性取代,R.sup.3和R.sup.4各代表氢原子或低烷基,但当R.sup.1和R.sup.5各代表苯基时,R.sup.2和R.sup.3不能代表氢。这些化合物具有有价值的生物学特性,主要可以应用于抗炎或利尿剂。
