The present invention relates to compounds of formula (I) ##STR1## in which R.sup.1 and R.sup.2 may be the same or different and stand for hydrogen, lower alkyl, lower cycloalkyl, or, taken together with the carbon atom (starred in formula I), bearing the groups X, R.sup.1 and R.sup.2, can form a C.sub.3 -C.sub.8 carbocyclic ring; X stands for hydrogen or hydroxy, R.sup.3 and R.sup.4, which may be the same or different stand for hydrogen, lower alkyl or halogen, n is 0, 1 or 2 and m is 0, 1 or 2. The present compounds, which find use both in the human and veterinary practice, show an immunomodulating effect as well as strong activity in inducing differentiation and inhibiting undesirable proliferation of certain cells, including cancer cells and skin cells.
本发明涉及式(I)的化合物:##STR1## 其中,R.sup.1和R.sup.2可以相同也可以不同,代表氢、较低的烷基、较低的环烷基,或与式(I)中标记为星号的碳原子结合,带有基团X、R.sup.1和R.sup.2,可以形成一个C.sub.3-C.sub.8的环烷基;X代表氢或羟基,R.sup.3和R.sup.4可以相同也可以不同,代表氢、较低的烷基或卤素,n为0、1或2,m为0、1或2。这些化合物在人类和兽医实践中均有用处,具有免疫调节作用,同时在诱导分化和抑制某些细胞的不良增殖,包括癌细胞和皮肤细胞方面具有强大的活性。
