New quinone compounds of the formula: ##STR1## wherein R.sup.1 is methyl or methoxy, or the two R.sup.1 groups jointly represent --CH.dbd.CH--CH.dbd.CH--; X is --CH.dbd.CH-- or --C.dbd.C--; Y.sup.1 is hydrogen, hydroxyl, carboxyl, cyano, acyloxy or --COZ in which Z is amino which may be substituted; m is zero or an integer of 1 to 3; n is zero or an integer of 1 to 10; n' is an integer of 1 to 5; k is an integer of 1 to 3; and when k is 2 or 3, n' is optionally variable within the range of 1 to 5 in each occurrence of the --X--(CH.sub.2).sub.n' group; and their hydroquinone forms and salts, have useful physiological activities such as antiasthmatic, antiallergic and bloodpressure decreasing activities.
新的喹醌化合物的化学式为:##STR1## 其中R.sup.1是甲基或甲氧基,或两个R.sup.1基团共同表示为--CH.dbd.CH--CH.dbd.CH--;X是--CH.dbd.CH--或--C.dbd.C--;Y.sup.1是氢、羟基、羧基、氰基、酰氧基或--COZ,其中Z是可能被取代的氨基;m为0或1到3的整数;n为0或1到10的整数;n'为1到5的整数;k为1到3的整数;当k为2或3时,n'在--X--(CH.sub.2).sub.n'基团的每次出现中可以选择地变化在1到5的范围内;它们的氢喹醌形式和盐具有有用的生理活性,如抗哮喘、抗过敏和降低血压的活性。
