1 Source of materials
All reagents were commercially available and used without further purification. An amount of 0.1123 g of isonicotinic acid hydrazide (0.819 mmol), 0.1364 g of phthalic acid (0.821 mmol), 0.1619 g of 2,2-dihydroxybenzophenone (0.818 mmol) and 3.0 mL of methanol were added into a screw-top dram vial (with rubber septum) and stirred at 300 rpm at 60 °C for 10 min. The vial was closed, and the solution was allowed to reflux at 60 °C for 24 h. The solution was then left slightly open to allow slow evaporation at room temperature. Colourless needles were observed after 3 days.
2 Experimental details
C-bound hydrogen atoms were located in the difference map then positioned geometrically and were allowed to ride on their respective parent atoms with thermal displacement parameters 1.2 times of the parent C atom. The coordinates and isotropic displacement parameters of all N-bound and O-bound H atoms were allowed to refine freely. Diagrams and publication material were generated using ORTEP-3 [4], WinGX [5] and PLATON [6].
3 Comment
For over 50 years, isoniazid has been used as a first-line pharmaceutical drug for the treatment of Mycobacterium tuberculosis. However, the mycobacterium has developed resistance to isoniazid due to certain genetic mutations (Shehzad et al. [7]). It is therefore beneficial to modify the NH2 functional group of isoniazid, as this covalent modification has often shown to be effective against multi-drug resistant tuberculosis strains (Setshedi et al. [8]). In this study, isoniazid was covalently modified with phthalic acid, and a salt was formed from an interaction with a second phthalic acid molecule, resulting in the product presented here.
As shown in the figure, the asymmetric unit contains a salt formed via one molecule of 4-((1,3-dioxoisoindolin-2-yl)carbamoyl)pyridine-1-ium and one molecule of 2-carboxybenzoate. The two molecules are held together by a hydrogen bond between H2 on the pyridinium ring and O7 of the carboxylate moiety on the phthalic acid molecule. Furthermore, a hydrogen bond exists between the H1 donor on the carbohydrazide moiety of the modified isoniazid and the O4 acceptor atom of the carboxylic acid moiety of phthalic acid. The carboxylic acid and carboxylate moieties on phthalic acid form an expected intramolecular S(6) hydrogen bond [9], between the H5a donor and the O6 acceptor. All bond lengths and angles are as expected [10, 11].
