Synthesis, crystal structure, vibrational spectral and density functional studies of 4-(1,3-dioxoisoindolin-2-yl)antipyrine

The 4-(1,3-dioxoisoindolin-2-yl)antipyrine, C19H 15N3O3, was synthesized by the condensation reaction of 4-aminoantipyrine and phthalic anhydride in ethanol solution using triethylamine as catalyst, and characterized by X-ray diffraction and spectral techniques. The experimental spectral bands were structurally assigned with the theoretical calculation, and the thermodynamic properties of the studied compound were obtained from the theoretically calculated frequencies. The linear polarizability (α0) and first hyperpolarizabilities (β0) calculated at B3LYP/6-31G(d) level are of 33.6921 A?3 and 2.7835 × 10-30 cm5/esu, respectively. The NBO analysis reveals that the studied molecule presents a structural characteristic of long-range electron-transfer with the energy gap of ≥3.639 eV. The frontier molecular orbitals are responsible for the electron polarization and long-range electron-transfer properties. The results indicate that the compound might be an excellent candidate of photo-responsive materials.

Studies on new cyclic imides obtained from aminophenazone with analgesic properties / Potent effects of a 3,4-dichloromaleimide derivative

This paper describes the synthesis of new cyclic imides obtained by reaction with aminophenazone (CAS 58-15-1, 4-aminoantipyrine) and different anhydrides with further cyclization with acetic acid under reflux. Their Structures were confirmed by spectral data (IR and NMR) and elemental analysis. The analgesic activity of the synthesized compounds was investigated initially with the writhing test in mice and the most promising compound, a 3,4-dichloromaleimide derivative (3), was analyzed using other models of nociception. The results indicated that compound 3 exerts potent analgesic activity in mice, being more active than some reference drugs. The analgesia caused by this compound was not reversed by naloxone in the writhing test. In the hotplate test, compound 3 did not increase the latency period of pain induced by thermal stimuli, confirming that it does not interact with opioid systems.
