1,2,4-Oxadiazole derivatives of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 =H, halogen or alkyl, or two of them represent the --CH.dbd.CH--CH.dbd.CH-- group required to form a fused benzene ring and R=an amino radical NR'R" or --N.dbd.CR'.sub.3 --NR'.sub.1 R'.sub.2, in which R', R", R'.sub.1 and R'.sub.2 =alkyl, hydroxyalkyl or N,N-dialkylaminoalkyl or NRR' or NR'.sub.1 R'.sub.2 =heterocyclic ring, and R' and R" can also be H, dialkylaminoalkylcarbonyl and pyridinoalkyl, (at least two of R.sub.1 to R.sub.5 being other than H when R' and R"=H), are pharmaceutically useful as anti-hypertensive agents.
该专利涉及一种1,2,4-噁二唑衍生物,其化学式为##STR1##其中R.sub.1,R.sub.2,R.sub.3,R.sub.4和R.sub.5 = H,卤素或烷基,或其中两个代表--CH.dbd.CH--CH.dbd.CH--基团以形成融合苯环,并且R = 氨基基团NR'R"或--N.dbd.CR'.sub.3--NR'.sub.1R'.sub.2,在其中R',R",R'.sub.1和R'.sub.2 = 烷基,羟基烷基或N,N-二烷基氨基烷基或NRR'或NR'.sub.1R'.sub.2 = 杂环环,并且R'和R"也可以是H,二烷基氨基烷基羰基和吡啶基烷基,(当R'和R" = H时,至少R.sub.1到R.sub.5中的两个不是H),作为降压药物具有药学上的用途。
