To characterize the structure of the test substance, a few kinds of analysis (X-ray diffraction, elemental, thermal) as well as a few kinds of spectroscopy (UV, IR, and NMR) have been used. The study of the action mechanism of the compound as a potential drug was carried out by evaluating the inhibitory activity against HIV-1 RT wild-type and its mutant forms corresponding to drug-resistant viral strains.Results. The studies have been carried out to confirm the structure of 1-[2-(2-benzoylphenoxy)ethyl]-6-methyluracil. The UV spectrum has a pronounced absorption maximum when measuring a solution of the substance in tetrahydrofuran at the concentration of 0.10 mg / ml. In the IR spectrum, there are specific bands in the range of 4000-370 cm–1. These factors make it possible to use UV and IR spectra to identify the test compound in the substance. It has also been established that the number and mutual arrangement of functional groups, the integrated intensity of signals in the 1H-NMR spectrum, as well as the structure of the carbon skeleton, correspond to the structure of 1-[2-(2-benzoylphenoxy) ethyl]-6-methyluracil. The results of studying the action mechanism showed that the test compound is an effective inhibitor of wild-type HIV-1 RT with an inhibition constant of 0.2 µM, as well as an enzyme inhibitor (mutation G190A) with an inhibition constant of 8 µM; enzyme (mutation Y181C) with an inhibition constant of 10 µM, as well as a reverse transcriptase (RT) inhibitor (mutation L100I, K103N, V106A) and a double mutant K103N / Y181C with an inhibition constant of more than 20 µM.Conclusion. As a result of the performed X-ray structural, elemental, 1H-NMR and 13C-NMR analyzes, the structure of 1-[2-(2-benzoylphenoxy)ethyl]-6-methyluracil has been confirmed. The possibility of using UV, IR and NMR spectroscopy, as well as thermal analyzes to confirm the authenticity during the verification of 1-[2-(2-benzoylphenoxy)ethyl]-6-methyluracil, has been shown. The developed methods can be used in the quality control and included in the draft of practice guidelines for the investigated substance. The studies of the action mechanism of the compound of HIV-1 RT reverse transcriptase have shown that this compound belongs to the group of non-nucleoside reverse transcriptase inhibitors (NNRTIs) of HIV-1.","PeriodicalId":20025,"journal":{"name":"Pharmacy & Pharmacology","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85888822","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 quantum-chemical parameters of the 4 analyzed groups of the compounds, have been calculated by the semi-empirical method PM7 (WinMopac 2016 program) on the workstation with an Intel Xeon E5-1620 3.5 GHz processor, 20 GB of RAM.Results and discussion. When comparing the quantum chemical parameters of the analyzed compounds, it was established that when the C-7 → C-8 multiple bond is formed, the free valency and unsaturation indices increase on both carbon atoms of the vinylene group in flavones and flavonols compared to the corresponding flavanones and flavanonols. This is explained by the fact that the value of the bond numbers Nµ on these atoms, on the contrary, decreases (Fµ = 4.732-Nµ). The transition from flavanone to flavone is accompanied by the formation of a vinyl group C-7 → C-8, and therefore both atoms from the sp3-hybridized state go into the sp2-state. The consequence of this transformation is a change in the electronegativity value and an increase in the unsaturation index of C-7 and C-8 atoms: C sp3 = 2.5;  Csp2 = 2.8. At the same time, the transition from flavanone to flavone leads to the formation of a conjugated system with the participation of π-electrons of the aromatic system “B”, C-7, C-8 atoms and the carbonyl group, which is commonly called the “main conjugation chain”. These structural changes, namely, the transition from a less oxidized flavanone to a more oxidized flavone, contribute to a decrease in the electron density on C-7 and C-8 atoms, and an increase in the total unsaturation of the molecules in general. Mulliken charges on C-7 of all groups of compounds are characterized by a positive value. As for the carbon atoms of the B fragment, the following features are revealed here: in the presence of one substituent -OH or -OCH3 on the carbon atom to which the substituent is bounded, the Mulliken charge is positive; if there are two substituents in the B ring -OH or -OCH3, as well as two -OCH3 groups, then the carbon atoms bonded to the indicated substituents also have a positive Mulliken charge; in the case of trihydroxy substituted in the C-2, C-3 and C-4 B ring, all three carbon atoms are characterized by a positive Mulliken charge; if there are methoxy groups in positions C-2, C-3 and C-4, then the positive Mulliken charge is concentrated only on C-2 and C-4 atoms, and on C-3 atom this charge has a negative value.Conclusion.

The production of new piracetam derivatives with high nootropic activity is a promising direction in the development of new neuroprotective drugs.The aim of the study is to predict GABA-ergic and glutamatergic activities of N-acyl derivatives of 2-(2-oxopyrolidin-1-yl)- acetamide by a molecular docking method through the energy analysis of interaction of modeled structures with GABAA and AMPA receptors with their subsequent targeted synthesis.Materials and methods. The objects of the research are new N-acyl derivatives of 2-oxo-1-pyrrolidineacetamide and a virtual model of the GABAA receptor of the Homo sapiens organism with the identification code 6D6U and a three-dimensional model of the AMPA-receptor of the Rattus norvegicus organism with the identification code 3LSF from the RCSB PDB database. The simulated compounds were designed in the HyperChem 8.0.8 program. This program was also used to optimize geometry using the force field of molecular mechanics MM+. Molecular docking was carried out using the Molegro Virtual Docker 6.0.1 program. The preparation of N-acyl derivatives of 2-(2-oxopyrrolidin-1-yl)-acetamide was carried out by the interaction of 2-(2-oxopyrrolidin-1-yl)-acetamide with an excess of the corresponding anhydride under conditions of acid catalysis.Results. Based on the results of molecular docking, a high affinity of all simulated compounds for the binding site of GABAA and AMPA receptors can be estimated. According to the predict, the maximum GABA-ergic activity should be expected for (N-[2-(2-oxopyrrolidin-1-yl)-acetyl]-butyramide. N-acyl derivatives of 2-oxo-1-pyrrolidineacetamide form a more stable complex with amino acid residues Arg207, Phe200, Thr202, Tyr97, Tyr157, Tyr205 and Phe65 of the GABAA receptor binding site than the GABA molecule. In terms of the minimum interaction energy, the N-acyl derivatives of 2-(2-oxopyrrolidin-1-yl)- acetamide are superior to a number of known ligands such as GABA, piracetam, anipiracetam, picamilon and pramiracetam. The tested compounds have also shown a high affinity for the binding site of the AMPA receptor. The leader compound is also the compound PirBut, as in the case of the GABAА receptor.Conclusion. Molecular modeling of the ligands interaction with the active binding site of gamma-aminobutyric acid of the GABAA receptor by molecular docking showed that all virtual N-acyl derivatives of 2-oxo-1-pyrrolidineacetamide can exceed a number of nootropic drugs by activity. In the course of molecular design, a method for predicting a glutamatergic activity for 2-pyrrolidone derivatives has been developed. It suggests a significant nootropic activity for N-[2-(2-oxopyrrolidin-1-yl)- acetamide amides.","PeriodicalId":20025,"journal":{"name":"Pharmacy & Pharmacology","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87346105","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 largest number of cases was registered in patients aged from 18 to 30 years, with female patients prevailing. Among the clinical manifestations of ADR, the most cases were drug hypersensitivity reactions of varying severity (40 cases) and disorders of the gastrointestinal tract (18 cases). The study of the problems associated with the use of antianaemic drugs made it possible to determine that the highest rates of DRP values were observed with the use of iron preparations for parenteral use and cyanocobalamine. The minimal DRP values were observed when prescribing iron protein succinylate preparations.Conclusion. The basis of pharmacotherapy for various types of anemias is the replenishment of iron and vitamin B12 (cyanocobalamin) depots. The effectiveness of the treatment in these cases largely depends on the patient's adherence to treatment, which is, in turn, depends on the frequency and severity of ADRs that occur during the use of antianaemic drugs.","PeriodicalId":20025,"journal":{"name":"Pharmacy & Pharmacology","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73581622","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}
