In our study, we have taken some of the anticancer drugs to investigate the interaction energy for drug-DNA complexes. Among the different binding modes of anticancer drugs; minor and major groove binding in DNA base pair is also an important aspect for anticancer drugs; therefore some anticancer drugs may be minor groove specific and some may be major groove specific. Since, such sequence-specific experimental studies for drug-DNA nucleobase complexes are very complicated and hence this may be investigated by using quantum mechanical theoretical studies, using M062X basis set. Our studies reveal that the stacked models of anticancer drugs-DNA nucleobase (AT and GC) complexes always show negative interaction energy values and among all such complexes the most negative interaction energy value results the most stable and favoured stacked systems. The stacking interaction energies for anticancer drugs-DNA nucleobase (AT and GC) complexes can easily be reflected in the interaction of energy plots.","PeriodicalId":20084,"journal":{"name":"Physical Chemistry Research","volume":"9 1","pages":"673-688"},"PeriodicalIF":1.2,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49018669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structure of the ferric porphyrin derivative (I) was optimized by using various quantum chemical methods: HF, B3PW91, BPV86, and B3LYP with three bases set 3-21, 6-31 G (d, p), and 6-311 G (d, p). The theoretical structural parameters of (I) are very close to those obtained by X-ray molecular structure. From the optimized structure, several parameters such as the HOMO-LUMO energies, the dipole moments, the molecular electrostatic potentials, the Mulliken electronegativity, the chemical hardness, and the electronic potential were calculated and discussed. On the other hand, the absorption properties of (I) were obtained and compared with those obtained with the experimental UV-visible spectrum. The reactivity of our [FeIII (TMPP) (4-CNpy)2] + ion complex using various descriptors such as local softness, electrophilicity, electronegativity, hardness, HOMO-LUMO gap, were calculated and the Hirschfeld data of the crystal packing of (I) were discussed.","PeriodicalId":20084,"journal":{"name":"Physical Chemistry Research","volume":"9 1","pages":"701-713"},"PeriodicalIF":1.2,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44746234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All designed derivatives were optimized at the B3LYP/3-21G level of theory. Charge distribution, polarizability, and thermodynamic properties such as free energy, heat capacity, and entropy of modified derivatives were explored in the subsequent analysis to evaluate how certain groups impact the drug properties. To understand the mode of binding and molecular interaction, molecular docking calculation was carried out to point out the potential inhibitors of the SARS-CoV-2 main protease (PDB: 6Y84 and 6LU7) by screening a total of fourteen derivatives which exhibited significant antibacterial and antifungal activities. It was observed that all derivatives were thermodynamically more stable and some of them were more chemically reactive than others. Most of the compounds, studied out here could bind near the crucial catalytic residues, HIS41, and CYS145 of the main protease, and the compounds were surrounded by other active site residues like GLY143, MET49, MET165, GLY143, HIS163, PRO168, GLU166, GLN189, and SER144. Finally, all the modified uridine derivatives were analyzed in silico ADMET and drug-like properties. Our patulous computational and statistical analysis showed that these selected uridine derivatives may use as potential inhibitors against the SARS-CoV-2 Mpro.","PeriodicalId":20084,"journal":{"name":"Physical Chemistry Research","volume":"9 1","pages":"385-412"},"PeriodicalIF":1.2,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42021899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesized catalyst was characterized by XRD, SEM, EDX and BET surface area analysis. The X-rays diffraction pattern confirmed that the crystal structure of ZnFe2O4 after stabilization on CS zeolite has not changed. The SEM images showed that, despite their varying sizes, the particles all have the same shape. Photocatalytic activity of the catalyst was tested for the degradation of ethylbenzene (EB) in water by UV + H2O2 method in the reverse-flow packed bed photo reactor. The process optimization and modeling were performed using the full factorial method. The initial concentration of EB = 30 ppm, pH = 9 and initial H2O2 concentration = 15 ppm were the best conditions. Under ideal process conditions, the removal efficiency of EB was greater than 99.5%. The validity of the Langmuir-Hinshelwood kinetics model was confirmed using EB photocatalytic degradation experimental results. The values of 〖∆H〗^⫲and 〖∆S〗^⫲ for the photocatalytic degradation of EB by ZnFe2O4/CS catalyst in the UV+H2O2 process were calculated based on the transition state theory and gave 1.67 kJ mol-1 and -263.057 J K-1 mol-1 respectively.","PeriodicalId":20084,"journal":{"name":"Physical Chemistry Research","volume":"9 1","pages":"539-552"},"PeriodicalIF":1.2,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68049519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
