Novel bis-basic esters and amides of xanthene and xanthone of the formula ##SPC1## Wherein: Z is oxygen or H.sub.2 ; each of R.sup.1 and R.sup.2 is hydrogen, (lower)-alkyl of 1 to 6 carbon atoms, cycloalkyl of 3 to 6 ring carbon atoms, alkenyl of 3 to 6 carbon atoms having the vinyl unsaturation in other than the 1-position of the alkenyl group, or each set of R.sup.1 and R.sup.2 taken together with the nitrogen atom to which they are attached is pyrrolidino, piperidino, N-(lower)alkylpiperazino, or morpholino; Each A is alkylene of 2 to about 8 carbon atoms and separates its adjacent Y and amino nitrogen by an alkylene chain of at least 2 carbon atoms; and each Y is oxygen, or >N--R wherein R is hydrogen or (lower)-alkyl of 1 to 4 carbon atoms; Or a pharmaceutically acceptable acid addition salt thereof. These compounds can be used as pharmaceuticals for preventing or inhibiting a viral infection.
这是一种新型的黄酮和黄酮酮的双碱基酯和酰胺,化学式为##SPC1## 其中:Z为氧或H.sub.2;每个R.sup.1和R.sup.2为氢,1至6个碳原子的(较低)烷基,3至6个环碳原子的环烷基,具有烯丙基不饱和度的3至6个碳原子的烯丙基,或每组R.sup.1和R.sup.2与它们附着的氮原子一起取代为吡咯烷基,哌啶基,N-(较低)烷基哌嗪基或吗啉基;每个A为2至约8个碳原子的烷基,并通过至少2个碳原子的烷基链将其相邻的Y和氨基氮分开;每个Y为氧或>N--R,其中R为氢或1至4个碳原子的(较低)烷基;或其药学上可接受的酸盐。这些化合物可用作预防或抑制病毒感染的药物。
