Homo-cysteinyl peptide inhibitors of the L1 metallo-beta-lactamase, and SAR as determined by combinatorial library synthesis

Homo-cysteinyl peptides were found to be more active than cysteinyl peptides toward L1 metallo-beta-lactamase as reversible competitive inhibitors. A combinatorial library of more than 90 homo-cysteinyl peptides was synthesized and screened for their inhibitory activity toward the L1 enzyme. A systematic structure-activity relationship analysis has revealed the preferred interaction groups for L1 conserved binding sites of beta-lactam substrates. The most active compound 95b, had a Ki of 2.1 nM.

Gold-catalyzed oxidative couplings of two indoles with one aryldiazo cyanide under oxidant-free conditions

Gold-catalyzed oxidative couplings of two indoles and one alpha-cyano gold carbene to form bis(indolyl)methane derivatives are described. Two different indoles are compatible with these reactions to provide reasonable yields. A plausible mechanism is postulated to rationalize the experimental data including product distributions, D2O labeling, and the significant effects of gold catalysts and cyano groups.

Electron transfer reduction of carboxylic acids using SmI 2-H2O-Et3N

The first general method for efficient electron transfer reduction of carboxylic acids has been developed. The protocol using SmI2 – H 2O – Et3N allows for reduction of a variety of carboxylic acids in excellent yields and provides an attractive alternative to processes mediated by reactive alkali metals, lithium aluminum hydride, and boron hydrides. Of broader significance, the method allows acyl radical equivalents to be generated from carboxylic acids under mild reaction conditions.

Synthesis, in vitro antiproliferative activities, and Chk1 inhibitory properties of indolylpyrazolones and indolylpyridazinedione

The synthesis of 5-indolylpyrazol-3-one, 4-indolylpyrazol-3-one and 4-indolyl-pyridazin-3,6-dione is reported. Their Chk1 inhibitory properties have been evaluated and their in vitro antiproliferative activities toward three tumor cell lines: murine leukemia L1210, human colon carcinoma HT29 and HCT116 have been determined. 4-Indolyl-pyridazin-3,6-dione is inactive against Chk1 and exhibits weak cytotoxicities toward the tumor cell lines tested. The IC50 values toward Chk1 of the two indolylpyrazolones are identical and are in the micromolar range, but the cytotoxicities of 4-indolylpyrazol-3-one are significantly stronger than those of 5-indolylpyrazol-3-one. Since 4-indolylpyrazol-3-one and 5-indolylpyrazol-3-one can present several conformers and tautomeric forms, molecular modelling in the ATP binding site of Chk1 has been carried out to investigate which form could induce the best stabilization in the active site of the enzyme. To get an insight into the kinase selectivity of these compounds, their inhibitory activities toward Src kinase were evaluated.

Improved chemoenzymatic asymmetric synthesis of (S)-Rivastigmine

(S)-Rivastigmine [(S)-1] was obtained via a four-step synthesis using an asymmetric enzymatic transamination protocol as the key step. An early introduction of the carbamate pharmacophore side chain avoided the use of protective group strategies and hence led to a considerable shortcut. This strategy required a novel omega-transaminase from Paracoccus denitrificans, which could transform the highly polar key substrate 3-acetylphenyl ethyl(methyl)carbamate (4) to the corresponding amine (S)-5 in 99% ee and >80% conversion.

Aromatic C-H borylation catalyzed by iridium/2,6-diisopropyl-N-(2- pyridylmethylene)aniline complex

The C-H borylation of aromatic and heteroaromatic compounds, such as benzene, 1,3-dichlorobenzene, 1,3-bis(trifluoromethyl)benzene, 2,6-dichloropyridine, indole, benzothiophene and benzofuran, by bis(pinacolato)diboron or pinacolborane was catalyzed by a 1/2 [IrCl(COD)] 2-2,6-diisopropyl-N-(2-pyridylmethylene)aniline complex. The isopropyl groups of the ligand are essential for obtaining the products in high yield. Octane was a suitable solvent for the reactions of the above compounds except for indole. In the case of indole, DME was better than octane and the yield tended to improve with a smaller amount of the catalyst.
