Experimental and theoretical structural studies of 5-amino-3-methylisoxazolo-4-carboxylic acid p-chlorophenylamide were performed. This compound belongs to a new class of isoxazole derivatives exhibiting promising immunological activity. The crystallographic structure was measured and compared with theoretical calculations for the investigated compound. The theoretical analyses were performed using Kohn-Sham density functional theory (DFT) with the B3LYP hybrid exchange-correlation energy functional and 6-311+G(d,p) basis set. The solvent effect was included using the SCRF/PCM method with water (epsilon=78) as a solvent. Topological analysis was performed in terms of Bader's theory of atoms in molecules, yielding molecular parameters for quantum molecular similarity investigations.
