Bys: Al-Janabi, Ali Jawad Kadhim and Yüksektepe Ataol, Çiğdem

The compound Lopinavir, which is used as an antiviral agent in COVID-19 and AIDS diseases caused by the coronavirus and HIV-1 viruses, is among the main drugs used to treat patients with such diseases. The molecular structure of the Lopinavir compound with the chemical formula C37H48N4O5 was investigated using computational chemistry methods. Density Functional Theory, which gives very good results for organic compounds, was used in the calculations. The molecular structure of the Lopinavir compound was obtained in the ground state from both gas and solvents with different dielectric constants and dipole moments, such as ethanol, acetone, chloroform, and water. The molecular structure of the Lopinavir compound was first optimized in gas and different solvent environments using the B3LYP/6-311G(d, p) and B3LYP/6-311+G(d, p) methods. A molecular electrostatic potential map was obtained using the optimized molecular structures of the Lopinavir compound. Molecular orbital energy values of the molecular structure of the Lopinavir compound were obtained, percentage contributions of functional groups to molecular orbital energy levels were calculated.
