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.
该发明涉及具有一般式(I)的新化合物,其中R1和R5分别代表苯基,可选择性地取代,R2代表氢、甲酰基、羧基、较低的烷氧羰基、羟基-(较低)-烷氧羰基或较低的烷基,可选择性地取代,R3和R4分别代表氢原子或较低的烷基,但当R1和R5分别代表苯基时,R2和R3不能代表氢。这些化合物具有有价值的生物学性质,主要可用作抗炎或利尿剂。
