The paper presents the synthesis of benzimidazole derivatives starting from asparagic acid. The reaction products were analysed from physical and chemical point of view and their biological activity (acute toxicity, anti-inflammatory activity and gastric tolerance) was evaluated. The product association with acetylsalicylic acid (Aspirin) improves its anti-inflammatory activity (higher with 38%). For acetylsalicylic acid dosing, in mixtures with benzimidazole derivatives, a new HPLC method has been proposed. The method is reproducible, selective and easy to manipulate. The derivatives based on benzimidazole and asparagic acid and their associates with acetylsalicylic acid present good anti-inflammatory properties.
