Abstract
Cyclodextrins (CDs) have been discovered to provide an efficient solution to the limited application of ester aroma molecules used in food, tobacco, and medication due to their strong smell and unstable storage. This work combined molecular modeling and experimental to analyze the conformation and controlled release of isomeric ester aroma compounds/β-CD inclusion complexes (ICs). The investigation revealed that ester aroma compounds could be effectively encapsulated within the β-CD cavity, forming ICs with low binding affinity. Furthermore, the key driving forces in ICs were identified as hydrogen bonds and van der Waals interactions through theoretical simulation. Results from the Fourier transform infrared (FTIR), nuclear magnetic resonance (NMR) and Isothermal titration calorimetry (ITC) experiments confirmed the intermolecular interaction predicted by the molecular model. Notably, the release rate of aroma compounds from L-menthyl acetate/β-CD (LMA/β-CD) IC exceeded that of terpinyl acetate/β-CD (TA/β-CD) IC. This difference is attributed to the length of the chain of aroma molecules and the variation in the position of functional groups, influencing the stable formation of ICs with β-CD. These findings hold potential implications for refining the application of ICs across diverse industries.

Abstract
The novel coronavirus disease-2019 (COVID-19), caused by SARS-CoV-2, is a global health pandemic beginning in early December 2019 in Wuhan, Hubei province, China. The effective drug target among coronaviruses is the SARS-CoV-2 main protease (Mpro), because of its crucial role in processing viral polyproteins translated from the viral RNA. In this study, the bioactivity of the selected thiol drug named Bucillamine (BUC) was evaluated as a potential drug for COVID-19 treatment by using computational modeling strategies. First, the molecular electrostatic potential density (ESP) calculation was performed to estimate the chemically active atoms of BUC. Additionally, BUC was docked to the Mpro (PDB: 6LU7) to evaluate the protein-ligand binding affinities. Besides, the estimated ESP results by density functional theory (DFT) were used to illustrate the molecular docking findings. Moreover, the frontier orbitals analysis was calculated to determine the charge transfer between the Mpro and BUC. Then, the stability of protein-ligand complex was subjected to the molecular dynamic simulations. Finally, an in silico study was performed to predict drug-likeness and absorption, distribution, metabolism, excretion and toxicity profiles (ADMET) of BUC. These results propose that BUC can be a potential drug candidate against the COVID-19 disease progression.Communicated by Ramaswamy H. Sarma.

Abstract
The structure assignment and conformational analysis of cinnamic derivative N-benzyl-N-(2-(cyclohexylamino)-2-oxoethyl) cinnamamide (NGI25) was carried out through Nuclear Magnetic Resonance (NMR) spectroscopy, Molecular Dynamics (MD) and Quantum Mechanics (QM), i.e. semiempirical and Density Functional Theory (DFT) calculations. Moreover, Homonuclear (COSY, NOESY) and heteronuclear (HSQC, HMBC) experiments were applied to assign its protons and carbons. After structure identification, NGI25 was subjected to computational calculations to reveal its most favorable conformations. In particular, MD studies were performed in two different solvents, DMSO of intermediate polarity and hydrophobic CHCl3. The obtained results suggest that NGI25 adopts similar conformations in both environments. In particular, the two aromatic rings of the molecule reside in spatial vicinity, while they remain quite distant from the cyclohexane. 2D NOESY experiments confirmed the in silico MD and QM calculations. Finally, molecular docking calculations were performed in order to reveal possible enzyme-targets for NGI25. Swiss target module was used to guide the discovery of new targets based on the structure of NGI. Indeed, it was predicted that NGI25 inhibited butyrylcholinesterase (BCHE) and lipoxygenase (LOX). Molecular docking experiments, followed by Molecular Dynamics studies, confirmed the favorable binding of NGI25 to both enzymes.Communicated by Ramaswamy H. Sarma.

Abstract
COVID-19 which is caused by the severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) has been declared pandemic in 2019. Though there is development of vaccines but there is an emergence requirement of drugs against SARS-CoV-2. Antiviral peptides can be rationally created and improved based on the known structures of viral proteins and their biological targets. In the given study, small peptide inhibitors with three amino acids are designed and docked against SARS-CoV-2 coronavirus using molecular docking approach. All the designed peptides bind at the active site but the highest binding affinity was observed for HisGluAsp. Molecular dynamics was performed to validate the stability and interactions of compound. The molecule has followed the druglikeness properties and with highest probability of being absorbed by the gastrointestinal tract. The results of the current investigation point to the possibility that the identified small peptides may prevent SARS-CoV-2 infection, although additional wet-lab tests are still required to confirm these results.
