This invention relates to new chemical compounds useful as drugs, as well as to pharmaceutical compositions containing the same. This application claims their hypocholesterolemic use. The new products are aromatic keto acid compounds with antiinflammatory as well as analgetic and hypocholesteremic acitvity and having the general formula: ##STR1## wherein R.sub.1 is hydrogen, halogen, phenyl, halophenyl, alkyl, phenoxy, or substituted phenoxy. R.sub.2 is hydrogen or alkoxy. R.sub.1 and R.sub.2 may form a ring, for instance: phenyl or cyclohexyl. R.sub.3 is always other than hydrogen, being either methyl (CH.sub.3) or methylene. When R.sub.3 is CH.sub.3, a double bond is present between the A and B carbons. When R.sub.3 is a methylene connected by a double bond to the B carbon, there can be only a single bond between the A and B carbons. The remaining valences of the A carbon atom are satisfied by hydrogen atoms. R.sub.4 may be OH, alkoxy, ##STR2## The drugs containing these active principles are useful in the prevention and treatment of inflammatory syndromes, pain, and conditions involving excess chloresterol.
本发明涉及新的化合物,可用作药物,以及包含它们的制药组合物。本申请声称它们具有降低胆固醇的用途。新产品是具有抗炎、镇痛和降胆固醇活性的芳香酮酸化合物,其一般式为:##STR1##其中R.sub.1为氢、卤素、苯基、卤代苯基、烷基、苯氧基或取代苯氧基。R.sub.2为氢或烷氧基。R.sub.1和R.sub.2可以形成一个环,例如:苯基或环己基。R.sub.3始终不是氢,可以是甲基(CH.sub.3)或亚甲基。当R.sub.3为CH.sub.3时,A和B碳之间存在双键。当R.sub.3是通过双键连接到B碳的亚甲基时,A和B碳之间只能有单键。A碳原子的其余价被氢原子满足。R.sub.4可以是OH、烷氧基、##STR2##含有这些活性成分的药物对于预防和治疗炎症综合症、疼痛以及涉及过多胆固醇的疾病非常有用。
