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 akyl 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.
具有以下式子的多预酚衍生物:##STR1## [其中A和B分别表示具有以下式子的基团--CH.sub.2 OR.sup.1(其中R.sup.1是氢原子,碳链中有一个杂原子的烷基,其盐的羧基或可选地在碳链中具有一个杂原子的脂肪酰基,芳香族酰基,杂环酰基,芳基烷酰基,杂环烷基酰基,无机酸或其盐的基团或其基团的自由基),或其中之一为基团--CH.sub.2 OR.sup.1,另一个为具有以下式子的基团--COOR.sup.2(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),具有以下式子的基团##STR2##或具有以下式子的基团##STR3##(其中R.sup.3和R.sup.4可以相同或不同,每个表示氢原子,可选地具有杂环取代基的烷基,芳基或芳基烷基,或R.sup.3和R.sup.4可以共同形成一个环,该环可选地包含其他杂环原子),n是0至4的整数,但当A和B均为基团--CH.sub.2 OR.sup.1时,R.sup.1中的任一种均表示具有杂原子的烷基,羧基或其盐,具有碳链中有一个杂原子的脂肪酰基,杂环酰基,杂环烷基酰基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。
