Article Abstract

The title compound 4-(5-nitro-thiophen-2-yl)-pyrrolo[1,2-a] quinoxaline (5NOTAAPP) was obtained by a straightforward catalyst-free reaction of 5-nitro-2- thiophene carboxaldehyde and 1-(2-aminophenyl) pyrrole in methanol and was structurally characterized by FT IR, UV-Vis, NMR spectroscopic techniques and elemental analysis. The structure of the compound has been confirmed by the single-crystal X-ray diffraction technique. The compound crystallizes in a monoclinic crystal system with space group P2/c. Unit cell dimensions:  = 12.2009(17) A,  = 8.3544(9) A,  = 13.9179(17) A and  = 104.980(5) A. Hirshfeld surface analysis was carried out to understand the different intermolecular interactions. The two-dimensional fingerprint plot revealed the most prominent interactions in the compound. Theoretical calculations were executed using Density functional theory (DFT) by Gaussian09 software to develop optimized geometry and frontier molecular orbital analysis. Molecular docking studies revealed that the title compound is a potent inhibitor of Main protease 3CL with PDB ID: 6LU7, the viral protease which is responsible for the new Corona Virus Disease (COVID-19).

Investigating solid-state photoreactivity, driven by crystal packing, has been a major enduring research theme in Crystal Engineering. Trans-3-styryl pyridine (3-StPy), an unsymmetric olefin, is photo-stable. However, when converted to a series of salts, they exhibited solid-state photoreactivity under UV irradiation.

This study presents the synthesis and characterization of novel cocrystal structures of theophylline (THE) with the amino acids gamma-aminobutyric acid (GABA) and l-arginine (ARG). Despite a large number of reports about THE cocrystals, no crystallographic parameters of cocrystals formed by THE and amino acids have been reported. THE is characterized by low solubility, while amino acids as cocrystal co-formers (CCFs) are increasingly recognized for their high solubility and safety.
