The invention relates to the benzylcyclanone derivatives of formula: ##STR1## where R.sub.1 and R.sub.3 denote H, OH, linear or branched C.sub.1 -C.sub.8 alkyl or linear or branched C.sub.1 -C.sub.8 alkoxy, R.sub.2 and R.sub.4 represent H or OH, at least one of the two being OH, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 represent H, C.sub.1 -C.sub.18 alkyl, aralkyl or aryl, it being possible for R.sub.5 and R.sub.6 and/or R.sub.7 and R.sub.8 to form an optionally substituted, saturated C.sub.5 -C.sub.12 ring, X represents O or --(CR.sub.9 R.sub.10).sub.n with n=1 or 2 and R.sub.9 and R.sub.10 represent H or CH.sub.3 ; if X represents --(CR.sub.9 R.sub.10).sub.n, R.sub.6 and R.sub.8, with the atoms of the ring to which they are attached, form a bicyclic system having 7 or 8 carbon atoms; if X represents --(CR.sub.9 R.sub.10).sub.n with n=1, R.sub.9 and R.sub.10 =CH.sub.3, R.sub.5 =H and R.sub.6 and R.sub.8, with the atoms of the ring to which are attached, form a bicyclic system having 7 carbon atoms, R.sub.7 can represent a --CH.sub.2 SO.sub.3 H residue, optionally in salt form. Process for preparing these compounds and their use as antioxidants and medicinal products for the treatment of skin allergies and inflammations.
该发明涉及具有以下结构的苯基环酮衍生物:其中R₁和R₃表示H、OH、直链或支链的C₁-C₈烷基或直链或支链的C₁-C₈烷氧基,R₂和R₄表示H或OH,其中至少有一个为OH,R₅、R₆、R₇和R₈表示H、C₁-C₁₈烷基、芳基烷基或芳基,其中R₅和R₆和/或R₇和R₈可以形成一个可选择取代的饱和的C₅-C₁₂环,X表示O或--(CR₉R₁₀)ₙ,其中n=1或2,R₉和R₁₀表示H或CH₃;如果X表示--(CR₉R₁₀)ₙ,R₆和R₈与它们连接的环原子形成一个具有7或8个碳原子的双环系统;如果X表示--(CR₉R₁₀)ₙ,其中n=1,R₉和R₁₀=CH₃,R₅=H,R₆和R₈与它们连接的环原子形成一个具有7个碳原子的双环系统,R₇可以表示一个--CH₂SO₃H残基,可选地以盐形式存在。制备这些化合物的方法及其作为抗氧化剂和治疗皮肤过敏和炎症的药物的用途。
