Identification of Potential Inhibitors of the Antigen 85C of Mycobacterium tuberculosis from Natural Resources by Virtual Screening

Tuberculosis, caused by Mycobacterium tuberculosis, is one of the deadliest infections in the world and, therefore, the search for new therapeutic alternatives is strongly required. A promising etiological agent?s molecular target for drug development is one of the mycolyltransferase enzymes, the 85C antigen (Ag85C), since it is crucial for the biosynthesis of myolates, essential elements of the bacterial cell wall. In this perception, the present work aimed to identify potential inhibitors against M. tuberculosis Ag85C by hierarchical virtual screening. For this, the ZINC15 natural products database was subjected to chemical similarity screening in order to select molecules in biologically relevant space. Subsequently, molecular docking was employed to list the natural products selected in the previous step according to their affinity to the enzyme active site. The complex with the best binding affinity was submitted to Molecular Dynamics (MD) simulation with the aim of evaluating its mechanical stability. Among 100,095 evaluated compounds, the isoxazoline derivative ZINC000107283125 was top ranked (GridScore -84.65 Kcal/mol), and therefore submitted to MD simulations. According to RMSD analysis there was less fluctuation of protein residues in the HOLO form than in the APO form, which indicates that ZINC000107283125 was able to stabilize the protein structure. The observed intermolecular (protein-ligand) interactions were similar to those described in the literature, of these, we highlight the hydrogen bond with Ser125. Therefore, this study contributed for the search of new and more selective and potent drugs against Ag85C.

Nucleophilic substitution reactions of N-methyl alpha-bromoacetanilides with benzylamines in dimethyl sulfoxide

Kinetic studies of the reactions of N-methyl-Y-a-bromoacetanilides with substituted X-benzylamines have been carried out in dimethyl sulfoxide at 25.0 C. The Hammett plots for substituent X variations in the nucleophiles (log kN vs sigmaX) are slightly biphasic concave upwards/downwards, while the Broensted plots (log kN vs pKa) are biphasic concave downwards with breakpoints at X = H. The Hammett plots for substituent Y variations in the substrates (log kN vs sigmaY) are biphasic concave upwards/downwards with breakpoints at Y = H. The cross-interaction constant pXY values are all negative: pXY = -0.32 for X = Y = electron-donating; -0.22 for X = electron-withdrawing and Y = electron-donating; -1.80 for X = electron-donating and Y = electronwithdrawing; -1.43 for X = Y = electron-withdrawing substituents. Deuterated kinetic isotope effects are primary normal (kH/kD > 1) for Y = electron-donating, while secondary inverse (kH/kD < 1) for Y = electronwithdrawing substituent. The proposed mechanisms of the benzylaminolyses of N-methyl-Y-a-bromoacetanilides are a concerted mechanism with a five membered ring TS involving hydrogen bonding between hydrogen (deuterium) atom in N-H(D) and oxygen atom in C = O for Y = electron-donating, while a concerted mechanism with an enolate-like TS in which the nucleophile attacks the a-carbon for Y = electronwithdrawing substituents. Copyright I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 33282-15-4, help many people in the next few years.Computed Properties of C10H7NO4

Photodriven Photocatalyst/Metal-Free Direct C-C/C-N Bond Formation: Synthesis of Indoles via EDA Complexes

The photodriven direct C-C/C-N bond formation initiated by electron donor-acceptor (EDA) complexes for the synthesis of indoles has been accomplished via [3+2] annulations of secondary arylamines with alkynes using IC4F9 as oxidants in the absence of any photocatalysts and metals. This green transformation exhibits the advantages of operational simplicity, good functional tolerances, and mild reaction conditions. The in situ generated EDA complexes derived from arylamines with alkynes were characterized by UV-vis absorption spectrometry and NMR titration experiments.

Synthesis, characterization, biological activities and molecular modeling of Schiff bases of benzene sulfonamides bearing curcumin scaffold

Curcumin has shown large number of pharmacological properties against different phenotypes of various disease models. Different synthetic routes have been employed to develop its various derivatives for diverse biological functions. In this study Schiff bases of benzenes sulfonamides bearing curcumin scaffold were synthesized to investigate their pharmacological effects. The structures of newly synthesized compounds were described by IR, 1H NMR and 13C NMR spectral data. The anti-inflammatory and antinociceptive activities of new compounds were evaluated with indomethacin and diclofenac sodium in experimental animal models respectively. COX-2 enzyme inhibition was evaluated with synthesized compounds through in vitro cyclooxygenase assays. Inhibition assays result revealed that compound 3a was the most potent compound. Molecular docking studies were also performed to identify the plausible binding mode of this compound. Antibacterial and antifungal activities were evaluated with ciprofloxacin, nystatin and ketoconazole using disk diffusion method and minimum inhibitory concentration values were determined by 96-well plate assay method. Our studies showed that compound 3a has promising antibacterial and anti-inflammatory while 3c has better antifungal activity as compared to reference drugs. Similarly the combination of more potent compounds 3a and 3c with ciprofloxacin and nystatin respectively gave significant synergic effect.

Efficient sonoelectrochemical decomposition of sulfamethoxazole adopting common Pt/graphite electrodes: The mechanism and favorable pathways

In this study, efficient degradation of sulfamethoxazole (SMX) with a high synergy factor of 14.7 was demonstrated in a sonoelectrochemical (US-EC) system adopting common Pt and graphite electrodes. It was found that the US-EC system could work effectively at broad pH range of 3?9, but would achieve good performances with appropriate electrochemical conditions at 20?mA/cm2 and 0.1?M Na2SO4. Both [rad]OH attacking and the anode oxidation would be responsible for the SMX degradation in the US-EC system, while the multiple promotional roles of US would be played homogenously and heterogeneously. US could not only effectively accelerate the decomposition of cathode-generated H2O2 into [rad]OH, but also lead to the enhancement in the heterogeneous reactions on the two electrodes, i.e. the cathode generation of H2O2 as well as the anode oxidation of SMX and H2O/OH?. Besides, the US-EC system would decompose SMX molecule via similar and simple pathways, by using either Na2SO4 or NaCl electrolytes. It was interesting to note that the US-EC system could successfully avoid the formation of complex chlorinated byproducts that detected in the referring EC system with NaCl. This finding would make the sonoelectrochemical processes favorable in treating practical wastewaters by alleviating the environmental impact of disinfection byproducts.
