论文简介:

Nucleic acids play an important role in cellular processes including cell division (DNA replication) and protein synthesis (transcription and translation). The deoxyribonucleic acid or DNA contains the genetic information necessary for the replication of the cell and its functioning after transcription of DNA into RNA and translation of RNA into proteins. These processes occur both in healthy cells, and in cancer cells, in which case they are targets for anti-cancer drugs. Two groups of medications concerning DNA: those, which protect DNA from alterations, due for example to radical reactions, causing cancers and those, which damage DNA of cancerous cells and microorganisms, while respecting if possible DNA of normal cells. Drugs, which damage nucleic acids, DNA and RNA, already constituted, inhibit cellular replication and function. They are used as antineoplastic agents and as antibiotics. Lipid-based vesicles are a very promising approach to treat diseases such as cancer, chronic infections and auto-immunity. Modern drug encapsulation methods allow efficient packing of therapeutic substances inside liposomes, thereby reducing the systemic toxicity of the drugs. Gene therapy is a technique for correcting defective genes responsible for disease development, which may be classified into two types: somatic and germ line gene therapy. Nucleic acid-based molecules (deoxyribonucleic acid, complementary deoxyribonucleic acid, complete genes, ribonucleic acid, and oligonucleotides) are utilized as research tools within the broad borders of gene therapy and the emerging field of molecular medicine.“Nucleic acid medicine” is a next generation …

论文简介:

In the present study, to predict corrosion inhibition performances of 2-amino-4-(4-chlorophenyl)-thiazole (Inh1), 2-amino-4-(4-bromophenyl)-thiazole (Inh2), 4-(2-aminothiazole-4-yl)-phenol (Inh3), 5,5′-(ethane-1, 2-diyldisulfanediyl) bis-(1,3,4-thiadiazole-2-amine) (Inh4), 5,5′-(propane-1,3-diyldisulfanediyl) bis-(1,3,4-thiadiazole-2-amine) (Inh5) against corrosion of Fe metal, density functional theory (DFT) calculations and molecular dynamics simulations approach were performed on these mentioned molecules. Firstly, quantum chemical parameters such as the highest occupied molecular orbital energy (EHOMO), lowest unoccupied molecular orbital energy (ELUMO), the energy gap between ELUMO and EHOMO (ΔE), chemical hardness, softness, electronegativity, proton affinity, global electrophilicity, global nucleophilicity and total energy (sum of electronic and zero-point energies) were calculated and discussed with the help of HF/SDD, HF/6-311G, HF/6-31 ++G, B3LYP/SDD, B3LYP/6-311G and B3LYP/6-31 ++G methods. Then, we calculated binding energies on Fe(110) surface of aforementioned thiazole and thiadiazole derivatives to investigate the strength of the interactions between metal surface and these molecules. The theoretical data obtained are in good agreement with the experimental inhibition efficiency results earlier reported.
