Despite tremendous efforts in the past two years, our understanding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), virus–host interactions, immune response, virulence, transmission, and evolution is still very limited. This limitation calls for further in-depth investigation. Computational studies have become an indispensable component in combating coronavirus disease 2019 (COVID-19) due to their low cost, their efficiency, and the fact that they are free from safety and ethical constraints. Additionally, the mechanism that governs the global evolution and transmission of SARS-CoV-2 cannot be revealed from individual experiments and was discovered by integrating genotyping of massive viral sequences, biophysical modeling of protein–protein interactions, deep mutational data, deep learning, and advanced mathematics. There exists a tsunami of literature on the molecular modeling, simulations, and predictions of SARS-CoV-2 and related developments of drugs, vaccines, antibodies, and diagnostics. To provide readers with a quick update about this literature, we present a comprehensive and systematic methodology-centered review. Aspects such as molecular biophysics, bioinformatics, cheminformatics, machine learning, and mathematics are discussed. This review will be beneficial to researchers who are looking for ways to contribute to SARS-CoV-2 studies and those who are interested in the status of the field.

In last few decades, nitrogen‐containing heterocycles have maintained their status as an important core of FDA‐approved drugs and medicinally active compounds. Quinoxaline is one such class of nitrogen‐containing scaffold that has become a subject of extensive research as it possess a plethora of biological activities. Molecular hybridization is a versatile and rational approach to drug design that involves the combination of two bioactive molecules possessing distinct intrinsic activity into a single scaffold for enhancing their therapeutic potential. In view of this, the advancement and potential of quinoxaline hybrids bearing thiazole, triazole, oxadiazole, pyrrolizines, pyrazole, etc. have attracted the keen attention of researchers to explore their therapeutic ability against different biological targets. The present review includes the research in the recent years (2018–2023) and addresses the graceful advancements in the studies related to quinoxaline‐based small molecules including their synthetic routes, biological activities and structure‐activity relationships. We anticipate that this review article will provide comprehensive knowledge of pharmacological importance of quinoxaline analogues and will fulfill the need of scientific community in designing and developing efficacious novel molecules.

“…The quinoxaline derivative 4-(5-nitro-thiophen-2-yl)-pyrrolo[1,2- a ]quinoxaline 5NO 2 TAAPP) 76 was prepared by Divya et al, 102 and tested its anti-SARS-CoV-2 main protease 3CL pro (PDB code: 6LU7) activity using molecular docking studies. The compound (5NO 2 TAAPP) 76 showed a lower binding energy towards SARS-CoV-2 main protease 3CL pro (−7.95Kcal mol −1 ) as compared to the reference drugs remdesivir (−4.96Kcal mol −1 ) and hydroxychloroquine (−6.06Kcal mol −1 ).…”

The Coronavirus disease 2019 (COVID-19) pandemic is one of the most considerable health problems across the world. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the major causative agent of COVID-19. The severe symptoms of this deadly disease include shortness of breath, fever, cough, loss of smell, and a broad spectrum of other health issues such as diarrhea, pneumonia, bronchitis, septic shock, and multiple organ failure. Currently, there are no medications available for coronavirus patients, except symptom-relieving drugs. Therefore, SARS-CoV-2 requires the development of effective drugs and specific treatments. Heterocycles are important constituents of more than 85% of the physiologically active pharmaceutical drugs on the market now. Several FDA-approved drugs have been reported including molnupiravir, remdesivir, ritonavir, oseltamivir, favipiravir, chloroquine, and hydroxychloroquine for the cure of COVID-19. In this study, we discuss potent anti-SARS-CoV-2 heterocyclic compounds that have been synthesized over the past few years. These compounds included; indole, piperidine, pyrazine, pyrimidine, pyrrole, piperazine, quinazoline, oxazole, quinoline, isoxazole, thiazole, quinoxaline, pyrazole, azafluorene, imidazole, thiadiazole, triazole, coumarin, chromene, and benzodioxole. Both in vitro and in silico studies were performed to determine the potential of these heterocyclic compounds in the fight against various SARS-CoV-2 proteins.
