Summary:Aim. To develop the method for the synthesis of the conjugate of diaminocalix[4]arene with 2-(2,3-dimethylphenyl)aminobenzoic acid (mefenamic acid) – bis-mefenamidocalixarene, determine its structure and physicochemical properties and assess its anti-exudative activity (AeA). Results and discussion. The conjugate of diaminocalixarene with mefenamic acid – bis-mefenamidocalixarene was synthesized at one step by the reaction of reactants in equimolar amounts in the presence of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide. The structure of the compound obtained was determined by spectral methods. AeA of bis-mefenamidocalixarene was studied in rats using the model of formalin edema. The results of the experimental studies showed that bis-mefenamidocalixarene exhibited the anti-exudative activity, which was equal to the reference drug – sodium diclofenac. Experimental part. The reaction of diaminocalixaren with 2- (2,3-dimethylphenyl)aminobenzoic acid (mefenamic acid) led to bis-mefenamidocalixarene with 40 % yield. The screening of AeA was carried out using modern digital plethysmometer (IITC Life Science (USA)). Conclusions. The effective one-stage method for the synthesis of the conjugate of diaminocalix[4]arene with 2-(2,3-dimethylphenyl)aminobenzoic acid – bis-mefenamidocalixarene has been developed. Its structure has been proven, and AeA has been studied. AeA is equal to the reference drug. It has been found that bis-mefenamidokalixaren synthesized is a promising compound for further profound studies.
