An air-stable binary Ni(0)?olefin catalyst

Nickel catalysis has become a growing and empowering area of research in recent years, providing new reactivity modes towards organic synthesis. In these endeavours, Ni(COD)2 (bis(1,5-cyclooctadiene)Ni(0)) vastly dominated this area, thus becoming the main source of Ni(0) for exploring new catalytic reactivity. However, all known Ni(0)?olefin precatalysts suffer from great instability and fast decomposition when exposed to air. With the aim of providing fast and facile technologies for practitioners, herein we report the synthesis, characterization and reactivity of an air stable binary Ni(0)?olefin complex, Ni(Fstb)3. This 16-electron complex features a unique arrangement of simple ligands that shield the nickel centre from oxygen. We demonstrate that Ni(Fstb)3 is an excellent precatalyst in a wide variety of important nickel-catalysed transformations and has unexpected catalytic properties compared with other Ni(0)?olefin complexes. As a general, practical and air-stable Ni(0) precursor, Ni(Fstb)3 represents a solution to a 60-year quest.

Optimization of Potent and Selective Tricyclic Indole Diazepinone Myeloid Cell Leukemia-1 Inhibitors Using Structure-Based Design

Myeloid cell leukemia 1 (Mcl-1), an antiapoptotic member of the Bcl-2 family of proteins, has emerged as an attractive target for cancer therapy. Mcl-1 upregulation is often found in many human cancers and is associated with high tumor grade, poor survival, and resistance to chemotherapy. Here, we describe a series of potent and selective tricyclic indole diazepinone Mcl-1 inhibitors that were discovered and further optimized using structure-based design. These compounds exhibit picomolar binding affinity and mechanism-based cellular efficacy, including growth inhibition and caspase induction in Mcl-1-sensitive cells. Thus, they represent useful compounds to study the implication of Mcl-1 inhibition in cancer and serve as potentially useful starting points toward the discovery of anti-Mcl-1 therapeutics.

Discovery of potent and selective inhibitors of human reticulocyte 15-lipoxygenase-1

There are a variety of lipoxygenases in the human body (hLO), each having a distinct role in cellular biology. Human reticulocyte 15-lipoxygenase-1 (15-hLO-1), which catalyzes the dioxygenation of 1,4-cis,cis-pentadiene- containing polyunsaturated fatty acids, is implicated in a number of diseases including cancer, atherosclerosis, and neurodegenerative conditions. Despite the potential therapeutic relevance of this target, few inhibitors have been reported that are both potent and selective. To this end, we have employed a quantitative high-throughput (qHTS) screen against ?74000 small molecules in search of reticulocyte 15-hLO-1 selective inhibitors. This screen led to the discovery of a novel chemotype for 15-hLO-1 inhibition, which displays nM potency and is >7500-fold selective against the related isozymes, 5-hLO, platelet 12-hLO, epithelial 15-hLO-2, ovine cyclooxygenase-1, and human cyclooxygenase-2. In addition, kinetic experiments were performed which indicate that this class of inhibitor is tight binding, reversible, and appears not to reduce the active-site ferric ion.

Br¡ãnsted-Acid-Promoted Rh-Catalyzed Asymmetric Hydrogenation of N-Unprotected Indoles: A Cocatalysis of Transition Metal and Anion Binding

The incorporation of Br¡ãnsted acid, thiourea anion binding, and transition metal catalysis enables an efficient method to synthesize chiral indolines via hydrogenation of indoles. Catalyzed by a rhodium/ZhaoPhos complex, asymmetric hydrogenation of unprotected indoles is performed smoothly with excellent enantioselectivities (up to 99% ee, up to 400 TON). Br¡ãnsted acid HCl activates indoles to form iminium ion intermediates. Mechanistic studies support the assumption that anion binding plays a crucial role as a secondary interaction. DFT calculations reveal an outer-sphere mechanism in this chemical transformation.

Design, synthesis, biological evaluation and docking study of novel indole-2-amide as anti-inflammatory agents with dual inhibition of COX and 5-LOX

In this work, a series of novel indole-2-amide compounds were designed, synthesized, characterized and the anti-inflammatory activity in vivo were evaluated. Compounds 8a, 10b, 12h, and 12l exhibited marked anti-inflammatory activity in 2,4-Dinitrofluorobenzenethe (DNFB) – induced mice auricle edema model. Further, compounds 8a, 10b and 12h exhibited potential in vitro COX-2 inhibitory activity (IC50 = 21.86, 23.3 and 23.21 nM, respectively), while the reference drug celecoxib was 11.20 nM. The most promising compound 10b was exhibited the highest selectivity for COX-2 (selectivity index (COX-1/COX-2) = 17.45) and moderate 5-LOX inhibitory activity (IC50 = 66 nM), which comparable to positive controlled zileuton (IC50 = 38.91 nM). In addition, the test results showed compounds 10b and 12h no significant cytotoxic activity on normal cells (RAW264.7). Further, at the active sites of the COX-1, COX-2 co-crystals, 3b and 4l showed higher binding forces in the molecular docking study, which consistent with the results of in vitro experiments. These results demonstrated that these compounds had dual inhibitory activity of COX/5-LOX, providing clues for further searching for safer and more effective anti-inflammatory drugs.

Synthesis and biological evaluation of isomeric methoxy substitutions on anti-cancer indolyl-pyridinyl-propenones: Effects on potency and mode of activity

Certain indolyl-pyridinyl-propenone analogues kill glioblastoma cells that have become resistant to conventional therapeutic drugs. Some of these analogues induce a novel form of non-apoptotic cell death called methuosis, while others primarily cause microtubule disruption. Ready access to 5-indole substitution has allowed characterization of this position to be important for both types of mechanisms when a simple methoxy group is present. We now report the syntheses and biological effects of isomeric methoxy substitutions on the indole ring. Additionally, analogues containing a trimethoxyphenyl group in place of the pyridinyl moiety were evaluated for anticancer activity. The results demonstrate that the location of the methoxy group can alter both the potency and the mechanism of cell death. Remarkably, changing the methoxy from the 5-position to the 6-position switched the biological activity from induction of methuosis to disruption of microtubules. The latter may represent a prototype for a new class of mitotic inhibitors with potential therapeutic utility.
