Based on the anticancer activity of novel quinoxalinyl-piperazine compounds, 1-[(5 or 6-substituted alkoxyquinoxalinyl)aminocarbonyl]-4-(hetero) arylpiperazine derivatives published in Bioorg. Med. Chem. 2010, 18, 7966, we further explored the synthesis of 7 or 8-substituted quinoxalinyl piperazine derivatives. From in vitro studies of the newly synthesized compounds using human cancer cell lines, we identified some of the 8-substituted compounds, for example 6p, 6q and 6r, which inhibited the proliferation of various human cancer cells at nanomolar concentrations. Compound 6r, in particular, showed the lowest IC50 values, ranging from 6.1 to 17 nM, in inhibition of the growth of cancer cells, which is better than compound 6k (compound 25 in the reference cited above). In order to select and develop a leading compound among the quinoxaline compounds with substitutions on positions 5, 6, 7 or 8, the compounds comparable to compound 6k in in vitro cancer cell growth inhibition were chosen and their pharmacokinetic properties were evaluated in rats. In these studies, compound 6k showed the highest oral bioavailability of 83.4%, and compounds 6j and 6q followed, with 77.8% and 57.6%, respectively. From the results of in vitro growth inhibitory activities and the pharmacokinetic study, compound 6k is suggested for further development as an orally deliverable anticancer drug.

HCV infections are the leading causes for hepatocellular carcinoma and liver transplantation in the United States. Recent advances in drug discovery have identified direct acting antivirals which have significantly improved cure rates in patients. Current efforts are directed towards identification of novel direct acting antiviral targeting different mechanism of actions which could become part of all oral therapies. We recently disclosed the identification of a novel tricyclic indole derived inhibitors of HCV NS5B polymerase that bound to the enzyme close to the active site. In this manuscript we describe further optimization of potency and pharmacokinetics (PK) of these inhibitors to identify compounds in low nM potency against gt-1b. These analogs also demonstrate excellent PK in rats and monkeys when administered as a dimethyl ethyl amino ester prodrug.

Organozinc intermediates (Reformatsky reagents) derived from alpha-bromocarboxylic acid esters react with acyl chlorides in the presence of dioxane to afford both C- and O-acylation products, 3-oxoalkanoic (3-acyloxy-2-alkenoic) acid esters and 1-acyloxy-1-alkoxyalkenes. The latter are formed as the only reaction products when the organozinc intermediate contains an alkyl group at the nucleophilic C2 center and when the acyl chloride possesses a bulky radical on the carbonyl group.

A series of twenty eight molecules of ethyl 5-(piperazin-1-yl)benzofuran-2-carboxylate and 3-(piperazin-1-yl)benzo[d]isothiazole were designed by molecular hybridization of thiazole aminopiperidine core and carbamide side chain in eight steps and were screened for their in vitro Mycobacterium smegmatis (MS) GyrB ATPase assay, Mycobacterium tuberculosis (MTB) DNA gyrase super coiling assay, antitubercular activity, cytotoxicity and protein-inhibitor interaction assay through differential scanning fluorimetry. Also the orientation and the ligand-protein interactions of the top hit molecules with MS DNA gyrase B subunit active site were investigated applying extra precision mode (XP) of Glide. Among the compounds studied, 4-(benzo[d]isothiazol-3-yl)-N-(4-chlorophenyl)piperazine-1-carboxamide (26) was found to be the most promising inhibitor with an MS GyrB IC50 of 1.77 ± 0.23 muM, 0.42 ± 0.23 against MTB DNA gyrase, MTB MIC of 3.64 muM, and was not cytotoxic in eukaryotic cells at 100 muM. Moreover the interaction of protein-ligand complex was stable and showed a positive shift of 3.5 C in differential scanning fluorimetric evaluations.

New pyridine-containing polyimides based on fluorinated gamma-pyridylenediamines (X = H, Cl, NH2, O-linkage) and dianhydride 6FDA were prepared by one-step polycondensation in benzoic acid melt. Molecular weight of the polymers enlarges with an increase of nucleophilicity of the pyridylenediamines and solubility of the macromolecules in the reaction medium. 4,4?-Oxydianiline was used as a co-monomer to prepare high-molecular pyridine-containing PI films with good mechanical properties. The polyimides and co-polyimides obtained are soluble in amide solvents, have good thermal and thermooxidative characteristics. Parameters of the polyimides pyrolysis, which provide consecutive elimination of different elements, were found.

The selective construction of carbon-fluorine bonds is of great interest to medicinal chemists because the replacement of a hydrogen or an oxygen atom with a fluorine atom in biologically active molecules can confer the molecules with improved physicochemical properties and biological activities. Since the first discovery of enantioselective fluorination using N-fluorocamphorsultam, our synthetic interest had been focused on the development of chiral N-fluorosulfonamide derivatives capable of enantioselective fluorination. However, these initial efforts revealed several limitations in both chemical yields and enantioselectivities of the fluorinated products. We present here the background of our personal story of the enantioselective fluorination reaction and some successful applications of the methods to the design and synthesis of biologically active products. Two novel approaches using cinchona alkaloid/Selectfluor combinations and chiral ligands/metal complexes have been pursued, respectively. In addition, the recent advances in this area by other groups are also described briefly.

Electric Literature of 10242-12-3, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 10242-12-3, 5-Nitrobenzofuran-2-carboxylic acid, introducing its new discovery.

Ribosylation reactions of previously silylated 3-carbethoxy-8-methyl-1,4-dihydro-4-oxoquinoline (6a) and 3-carbethoxy-6-methyl-1,4-dihydro-4-oxoquinoline (6b) with 1-O-acetyl-2,3,5-tri-O-benzoyl-beta-D-ribofuranose (7), under Lewis acid catalysis, were studied. The method using hexamethyldisilazane (HMDS)/trimethylchlorosilane (TMCS) mixture for silylation and anhydrous stannic chloride as catalyst for ribosylation failed to give any nucleoside product. On the other hand, the protected nucleoside 3-carbethoxy-6-methyl-1-(2,3,5-tri-O-benzoyl-beta-D-ribofuranosyl)-1,4- dihydro-4-oxoquinoline (8b) was obtained in good yields using bis(trimethylsilyl)trifluoroacetamide (BSTFA) containing 1% of TMCS and the same catalyst. Compound 8b was more easily isolated in higher yields with an improvement of the later method by replacing stannic chloride with trimethylsilyl trifluoromethanesulfonate (TMSOTf). De-O-benzoylation of 8b with methanolic sodium hydroxide solution afforded the free riboside 3-carbomethoxy-6-methyl-1-beta-D-ribofuranosyl-1,4-dihydro-4-oxoquinoline (9b). The structures of the obtained products were confirmed by their UV, MS, IR, 1H and 13C-NMR data.
