Glycyrrhetinic acid substituted at its 30 positions is of the general formula
where X and Y are H or together oxo, Z is a saccharide or -A₂-(CH₂)n-(CH=CH)m-A₁- and W is extensively defined, including of three further general formulae each terminating in substituted phenylpiperazine.
Synthesis can be by use of a glycosyl bromide and a condensing agent and optionally sulfation or phosphation.
The compounds and their salts have antiviral action, especially those which contain as the aglycon a 4-(substituted)phenylpiperazine-1-yl derivative.
Pharmaceutical compositions are described for oral, topical or injection administration.
The compounds and compositions are effective to treat viral diseases, e.g. herpes virus or influenza.
在 30 位上被取代的甘草次酸的通式为
其中 X 和 Y 是 H 或一起是氧代,Z 是糖或-A₂-(CH₂)n-(CH=CH)m-A₁-,W 的定义很广,包括三个通式,每个通式都以取代的苯基哌嗪结尾。
合成时可使用溴化糖基和缩合剂,也可选择硫酸化或磷酸化。
这些化合物及其盐类具有抗病毒作用,尤其是那些含有 4-(取代)苯基哌嗪-1-基衍生物作为苷元的化合物。
所述药物组合物可用于口服、局部或注射给药。
这些化合物和组合物能有效治疗病毒性疾病,如疱疹病毒或流感。
