The invention relates to compounds of formulae
wherein
R1 and R2 are independently from each other and signify lower alkoxy, lower alkenyloxy, benzyloxy, hydroxy, ―OCH(CH3)OC(O)-lower alkyl or ―OCH2C(O)N(R3)(R4), with the proviso that only one of R1 or R2 may be hydroxy;
R3 and R4 are independently from each other and signify hydrogen, lower alkyl, lower alkenyl or cycloalkyl; or
R1 and R2 form together with the carbon atom, to which they are attached the linking group X, wherein
X is ―O(CH2)nCH=CH(CH2)nO- or -O(CH2)mO-;
n is 1, 2 or 3; and
m is 4-8.
as well as pharmaceutically acceptable salts of said compounds. Compounds of the present invention can be used for the treatment of diseases where Serum Amyloid P Component depletion has a beneficial effect, in particular in the treatment or prevention of all forms of central and systemic amyloidosis.

其中
R1和R2彼此独立,分别表示低级烷氧基、低级烯氧基、苄氧基、羟基、-OCH(CH3)OC(O)-低级烷基或-OCH2C(O)N(R3)(R4),但R1或R2中只能有一个是羟基;
R3 和 R4 相互独立,表示氢、低级烷基、低级烯基或环烷基;或
R1 和 R2 与连接它们的碳原子一起形成连接基团 X,其中
X 是-O(CH2)nCH=CH(CH2)nO-或-O(CH2)mO-;
n 是 1、2 或 3;以及
m 为 4-8。
