The use is disclosed of compounds of the formula (I):-
where R' is methoxy, methylthio, trifluoromethyl, chloro, fluoro or bromo; R2 is hydrogen or with R1 is methylenedioxy; R3 is hydrogen or methyl; n is 0, 1 or 2; andX is -(CH2)m- where m is 0 to 4, 1,2-propanediyl, 1,3-propan-2 -oldiyl or 1,3-propan -2-onediyl and their pharmaceutically acceptable salts, provided that m is not 0 when R1 is chloro, as anti-arthritic agents. Also disclosed are pharmaceutical compositions comprising a compound of formula (I) as defined above or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier.
Some compounds of formula (I) are novel, such compounds have formula (I) where R' is methoxy, methylthio, trifluro-methyl, chloro, fluoro or brom; R2 is hydrogen or with R1 is methylenedioxy; R3 is hydrogen or methyl; n is 0, 1 or2; and X is -(CH2)m- where m is 0 to 4, 1,2-propanediyl, 1,3-propan-2 -oldiyl or 1,3-propan-2-onediyl, and pharmaceutically acceptable salts, provided that when R1 is chlorom is not 0 and when R1 is methoxy and n is 0 m is not 2. A process is disclosed for the preparation of these novel compounds.
本发明公开了式(I)化合物的用途
其中 R'是甲氧基、甲硫基、三氟甲基、氯、氟或溴;R2 是氢或与 R1 一起是亚甲基二氧基;R3 是氢或甲基;n 是 0、1 或 2;和 X 是-(CH2)m-(其中 m 为 0 至 4)、1,2-丙二基、1,3-丙-2-烯二基或 1,3-丙-2-壬二基及其药学上可接受的盐,条件是当 R1 为氯时,m 不为 0,作为抗关节炎剂。还公开了药物组合物,其中包含如上定义的式 (I) 化合物或其药学上可接受的盐以及药学上可接受的载体。
一些式 (I) 的化合物是新型的,此类化合物具有式 (I) 其中 R' 是甲氧基、甲硫基、三氟甲基、氯、氟或溴;R2 是氢或与 R1 一起是亚甲基二氧基;R3 是氢或甲基;n 是 0、1 或 2;和 X 是-(CH2)m-(其中 m 为 0 至 4)、1,2-丙二基、1,3-丙-2-烯二基或 1,3-丙-2-壬二基,以及药学上可接受的盐,条件是当 R1 为氯时,m 不为 0,当 R1 为甲氧基且 n 为 0 时,m 不为 2。本发明公开了制备这些新型化合物的工艺。
