Polyprenyl derivatives having the formula ##STR1## [wherein A and B individually represent a group of the formula --CH.sub.2 OR.sup.1 (wherein R.sup.1 is hydrogen atom, an alkyl group having an intervening hetero atom in the carbon chain, carboxyl group on its salt or an aliphatic acyl group optionally having an intervening hetero atom in the carbon chain, an aromatic acyl group, a heterocyclic acyl group, an araliphatic acyl group, a heterocyclic aliphatic acyl group or a radical of an inorganic acid or its salt) or where one of A and B represents the group --CH.sub.2 OR.sup.1, the other represents a group of the formula --COOR.sup.2 (wherein R.sup.2 represents hydrogen atom, a metal atom capable of forming a salt, an organic base or an alkyl group), a group of the formula ##STR2## or a group of the formula ##STR3## (wherein R.sup.3 and R.sup.4 may be the same or different and each represents hydrogen atom, an alkyl group optionally having a heterocyclic substituent, an aryl group or an aralkyl group or R.sup.3 and R.sup.4 may jointly form a ring optionally containing other hetero ring atom) and n is an integer of 0 to 4 inclusive, provided that when both A and B are the group --CH.sub.2 OR.sup.1, either of the R.sup.1 represents an alkyl group having an intervening hetero atom, carboxyl group or its salt, an aliphatic acyl group having an intervening hetero atom in the carbon chain, a heterocyclic acyl group, a heterocyclic aliphatic acyl group or a radical of an inorganic acid or its salt]. These derivatives are useful as medicines for treating peptic ulcer.
多萜衍生物具有以下结构式##STR1##[其中A和B分别表示结构式--CH.sub.2 OR.sup.1的基团(其中R.sup.1是氢原子,带有碳链中间杂原子的烷基基团,其盐中的羧基团或烷基酰基团,可选择带有碳链中间杂原子的脂肪酰基团,芳香族酰基团,杂环酰基团,芳基脂肪酰基团,杂环脂肪酰基团或者无机酸或其盐的自由基)或其中A和B之一表示结构式--CH.sub.2 OR.sup.1,另一个表示结构式--COOR.sup.2的基团(其中R.sup.2表示氢原子,能形成盐的金属原子,有机碱或烷基基团),结构式##STR2##的基团或结构式##STR3##的基团(其中R.sup.3和R.sup.4可以相同也可以不同,每个表示氢原子,可选择带有杂环取代基的烷基基团,芳基或芳基烷基基团或R.sup.3和R.sup.4可以共同形成一个环,该环可选包含其他杂环原子),n为0到4的整数,但当A和B都是结构式--CH.sub.2 OR.sup.1时,R.sup.1中的任一种表示带有中间杂原子的烷基基团,羧基或其盐,带有碳链中间杂原子的脂肪酰基团,杂环酰基团,杂环脂肪酰基团或无机酸或其盐的自由基]。这些衍生物可用作治疗消化性溃疡的药物。
