Chalcone?benzoxaborole hybrids as novel anticancer agents

In this study, we report the synthesis of a series of chalcone?benzoxaborole hybrid molecules and the evaluation of their anticancer activity. Their anticancer potency and toxicity were tested on three human cancer cell lines and two normal cell lines. The 4-fluoro compound 15 was found to be the most potent compound with an IC50value of 1.4 muM on SKOV3 cells. The 4-iodo compound 18 and 3-methyloxy-4-amino compound 47 showed good potency on SKOV3 cells while exhibiting low toxicity on normal cells. This work extended the application of benzoxaboroles to the field of anticancer research.

Bacterial Biofilm Inhibition, Hemolytic Activity, and Structure?Activity Relationship of N-(2,3-Dihydro-1,4-Benzodioxin-6-yl)-4-Nitro-N-(Substituted-Benzyl)benzenesulfonamides

Abstract: In the work, new antibacterial compounds that combine sulfonamide and benzodioxane fragments in their framework were fabricated. Structures of the sulfonamide derivatives were determined by the IR, 1H NMR, 13C NMR, and EI-MS spectroscopy techniques. Antibacterial potential of these molecules was ascertained by biofilm inhibition study against Escherichia coli and Bacillus subtilis. The results revealed that two of the compounds were rather active inhibitors of these two pathogenic bacterial strains. According to the hemolytic study, most of the new molecules are mildly cytotoxic and hence might be used as safe antibacterial agents.

2-Oxo-N-aryl-1,2,3,4-tetrahydroquinoline-6-sulfonamides as activators of the tumor cell specific M2 isoform of pyruvate kinase

Compared to normal differentiated cells, cancer cells have altered metabolic regulation to support biosynthesis and the expression of the M2 isozyme of pyruvate kinase (PKM2) plays an important role in this anabolic metabolism. While the M1 isoform is a highly active enzyme, the alternatively spliced M2 variant is considerably less active and expressed in tumors. While the exact mechanism by which decreased pyruvate kinase activity contributes to anabolic metabolism remains unclear, it is hypothesized that activation of PKM2 to levels seen with PKM1 may promote a metabolic program that is not conducive to cell proliferation. Here we report the third chemotype in a series of PKM2 activators based on the 2-oxo-Naryl-1,2,3,4-tetrahydroquinoline-6-sulfonamide scaffold. The synthesis, structure activity relationships, selectivity and notable physiochemical properties are described.

Pyrrolidine-3-carboxylic acids as endothelin antagonists. 2. Sulfonamide-based ET(A)/ET(B) mixed antagonists

When the N,N-dialkylacetamide side chain of the highly ET(A)-selective endothelin antagonist ABT-627 (1; [2R,3R,4S]-2-(4-methoxyphenyl)-4-(1,3- benzodioxol-5-yl)-1-[[(N,N-dibutylamino)carbonyl]methyl]pyrrolidine-3- carboxylic acid; A-147627) is replaced by N,S-dialkylsulfonami-doethyl, the resultant analogs retain ET(A) affinity, but exhibit substantial ET(B) affinity as well. Structure-activity studies reveal that modifications in the length of the two alkyl groups, and in the substitution on the anisyl ring, are important in optimizing this ‘balanced’ antagonist profile. In particular the combination of an N-n-propyl group, an S-alkyl chain between four and six carbons in length, and a fluorine atom ortho to the aromatic OCH3 provides compounds with sub-nanomolar affinities for both receptor subtypes, and with ET(A)/ET(B) ratios close to 1. A number of these compounds also exhibit oral bioavailabilities (in rats) in the 30-50% range and have substantial plasma half-lives. The balanced receptor-binding profile of these potent and orally bioavailable compounds complements the ET(A) selectivity observed with 1.

Nanoscale synthesis and affinity ranking

Most drugs are developed through iterative rounds of chemical synthesis and biochemical testing to optimize the affinity of a particular compound for a protein target of therapeutic interest. This process is challenging because candidate molecules must be selected from a chemical space of more than 1060 drug-like possibilities 1, and a single reaction used to synthesize each molecule has more than 107 plausible permutations of catalysts, ligands, additives and other parameters 2 . The merger of a method for high-throughput chemical synthesis with a biochemical assay would facilitate the exploration of this enormous search space and streamline the hunt for new drugs and chemical probes. Miniaturized high-throughput chemical synthesis 3-7 has enabled rapid evaluation of reaction space, but so far the merger of such syntheses with bioassays has been achieved with only low-density reaction arrays, which analyse only a handful of analogues prepared under a single reaction condition 8-13 . High-density chemical synthesis approaches that have been coupled to bioassays, including on-bead 14, on-surface 15, on-DNA 16 and mass-encoding technologies 17, greatly reduce material requirements, but they require the covalent linkage of substrates to a potentially reactive support, must be performed under high dilution and must operate in a mixture format. These reaction attributes limit the application of transition-metal catalysts, which are easily poisoned by the many functional groups present in a complex mixture, and of transformations for which the kinetics require a high concentration of reactant. Here we couple high-throughput nanomole-scale synthesis with a label-free affinity-selection mass spectrometry bioassay. Each reaction is performed at a 0.1-molar concentration in a discrete well to enable transition-metal catalysis while consuming less than 0.05 milligrams of substrate per reaction. The affinity-selection mass spectrometry bioassay is then used to rank the affinity of the reaction products to target proteins, removing the need for time-intensive reaction purification. This method enables the primary synthesis and testing steps that are critical to the invention of protein inhibitors to be performed rapidly and with minimal consumption of starting materials.
