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.

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

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.

Synthesis and cytoprotective characterization of 8-hydroxyquinoline Betti products

The 8-hydroxyquinoline pharmacophore scaffold has been shown to possess a range of activities as metal chelation, enzyme inhibition, cytotoxicity, and cytoprotection. Based on our previous findings we set out to optimize the scaffold for cytoprotective activity for its potential application in central nervous system related diseases. A 48-membered Betti-library was constructed by the utilization of formic acid mediated industrial-compatible coupling with sets of aromatic primary amines such as anilines, oxazoles, pyridines, and pyrimidines, with (hetero)aromatic aldehydes and 8-hydroxiquinoline derivatives. After column chromatography and re-crystallization, the corresponding analogues were obtained in yields of 13?90%. The synthesized analogs were optimized with the utilization of a cytoprotection assay with chemically induced oxidative stress, and the most active compounds were further tested in orthogonal assays, a real time cell viability method, a fluorescence-activated cell sorting (FACS)-based assay measuring mitochondrial membrane potential changes, and gene expression analysis. The best candidates showed potent, nanomolar activity in all test systems and support the need for future studies in animal models of central nervous system (CNS) disorders.
