Novel synthesis of heterocycle-containing adamantane derivatives

A novel approach to synthesize the of heterocycle-containing adamantane derivatives 1-{[(3-hydroxy-1-adamantyl)amino]acetyl}-2- cyano-(S)-pyrrolidine and N-{2-[4-(2-pyrimidinyl)-1-piperazinyl]ethyl}adamantane-1-carboxamide, which were effective in treatment of diabetes and depression respectively, have been described. The target compounds were synthesized by raw materials of inexpensive L-proline and available 1-(2-pyrimidinyl) piperazine respectively. Compared with traditional synthetic routes, the method provides several advantages such as inexpensive and readily available raw materials, convenient manipulation and high yield.

Discovery of a novel chemotype of potent human ENaC blockers using a bioisostere approach. Part 1: Quaternary amines

We report the identification of a novel series of human epithelial sodium channel (ENaC) blockers that are structurally distinct from the pyrazinoyl guanidine chemotype found in prototypical ENaC blockers such as amiloride. Following a rational design hypothesis a series of quaternary amines were prepared and evaluated for their ability to block ion transport via ENaC in human bronchial epithelial cells (HBECs). Compound 11 has an IC50 of 200 nM and is efficacious in the Guinea-pig tracheal potential difference (TPD) model of ENaC blockade with an ED50 of 44 mug kg-1 at 1 h. As such, pyrazinoyl quaternary amines represent the first examples of a promising new class of human ENaC blockers.

beta-Hydroxypiperidinecarboxylates: Additions to the chiral pool from bakers’ yeast reductions of beta-ketopiperidinecarboxylates

Reduction of the piperidine keto esters 16-19 using fermenting bakers’ yeast provides high yields of the corresponding hydroxy esters 20, 26, 32 and 37 respectively, exclusively as the cis-diastereoisomers and with good levels (?80%) of enantiomeric enrichment. The relative stereochemistries of the products were deduced from NMR data while the absolute configurations were determined by degradation to known piperidinemethanol derivatives or, in the case of hydroxy ester 37, by homologation to (R)-3-quinuclidinol 41b.

Combined Imine Reductase and Amine Oxidase Catalyzed Deracemization of Nitrogen Heterocycles

A novel amine oxidase (AO)/imine reductase (IRED) system was developed for the deracemization of racemic amines. By combining (R)-6-hydroxy-d-nicotine oxidase (6-HDNO) with an (R)-IRED, a panel of racemic 2-substituted piperidines and pyrrolidines were deracemized to yield the (S)-amines in high yields and enantiomeric excess values. Other N-heterocycles were deracemized with monoamine oxidase (MAO-N) or 6-HDNO in combination with ammonia borane, which allowed comparison of the two enzyme deracemization approaches with that involving a chemical reducing agent.

High- k Gate Dielectrics for Emerging Flexible and Stretchable Electronics

Recent advances in flexible and stretchable electronics (FSE), a technology diverging from the conventional rigid silicon technology, have stimulated fundamental scientific and technological research efforts. FSE aims at enabling disruptive applications such as flexible displays, wearable sensors, printed RFID tags on packaging, electronics on skin/organs, and Internet-of-things as well as possibly reducing the cost of electronic device fabrication. Thus, the key materials components of electronics, the semiconductor, the dielectric, and the conductor as well as the passive (substrate, planarization, passivation, and encapsulation layers) must exhibit electrical performance and mechanical properties compatible with FSE components and products. In this review, we summarize and analyze recent advances in materials concepts as well as in thin-film fabrication techniques for high-k (or high-capacitance) gate dielectrics when integrated with FSE-compatible semiconductors such as organics, metal oxides, quantum dot arrays, carbon nanotubes, graphene, and other 2D semiconductors. Since thin-film transistors (TFTs) are the key enablers of FSE devices, we discuss TFT structures and operation mechanisms after a discussion on the needs and general requirements of gate dielectrics. Also, the advantages of high-k dielectrics over low-k ones in TFT applications were elaborated. Next, after presenting the design and properties of high-k polymers and inorganic, electrolyte, and hybrid dielectric families, we focus on the most important fabrication methodologies for their deposition as TFT gate dielectric thin films. Furthermore, we provide a detailed summary of recent progress in performance of FSE TFTs based on these high-k dielectrics, focusing primarily on emerging semiconductor types. Finally, we conclude with an outlook and challenges section.

Synthesis, structures, and DFT bonding analysis of new titanium hydrazido(2-) complexes

The reaction of 1,1-diphenylhydrazine with Ti(NMe2) 2Cl2 produced the monomeric terminal titanium hydrazido(2-) species Ti(NNPh2)Cl2(HNMe2) 2 (1) in near-quantitative yield. The reaction of Ti(NMe 2)2Cl2 with the less sterically demanding ligand precursors 1,1-dimethylhydrazine or N-aminopiperidine gave the dimeric mu-eta2,eta1-bridged compounds Ti 2(mu-eta2,eta1-NNMe2) 2Cl4(HNMe2)2 (2) and Ti 2{mu-eta2,eta1-NN(CH2) 5}2Cl4(HNMe2)3 (3). The X-ray structures of 2 and 3 showed the formation of N-H…Cl hydrogen bonded dimers or chains, respectively. The reaction of 1 with an excess of pyridine formed [Ti(NNPh2)Cl2(py)2]n (4, n = 1 or 2). The reaction of the tert-butyl imido complex Ti(N tBu)Cl2(py)3 with either 1,1-dimethylhydrazine or N-aminopiperidine again resulted in the formation of hydrazido-bridged dimeric complexes, namely Ti2(mu-eta2, eta1-NNMe2)2Cl4(py)2 (5, structurally characterized) and Ti2{mu-eta2, eta1-NN(CH2)5}2Cl 4(py)2 (6). Compounds 1 and 4 are potential new entry points into terminal hydrazido(2-) chemistry of titanium. Compound 1 reacted with neutral fac-N3 donor ligands to form Ti(NNPh2)Cl 2(Me3[9]aneN3) (7), Ti(NNPh2)Cl 2(Me3[6]aneN3) (8), Ti(NNPh2)Cl 2{HC(Me2pz)3} (9, structurally characterized), and Ti(NNPh2)Cl2{HC(nBupz)3} (10) in good yields (Me3[9]aneN3 = trimethyl-1,4,7- triazacyclononane, Me3[6]aneN3 = trimethyl-1,3,5- triazacyclohexane, HC(Me2pz)3 = tris(3,5- dimethylpyrazolyl)methane, and HC(nBupz)3 = tris(4- nbutylpyrazolyl)-methane). DFT calculations were performed on both the model terminal hydrazido compound Ti(NNPh2)Cl2{HC(pz) 3} (I) and the corresponding imido compounds Ti(NMe)Cl 2{HC(pz)3} (II) and Ti(NPh)Cl2{HC(pz) 3} (III). The NNPh2 ligand binds to the metal center in an analogous manner to that of terminal imido ligands (metal?ligand triple bond), but with one of the Ti=Nalpha pi components significantly destabilized by a pi* interaction with the lone pair of the N beta atom. The NR ligand sigma donor ability was found to be NMe > NPh > NNPh2, whereas the overall (sigma + pi) donor ability is NMe > NNPh2 > NPh, as judged by fragment orbital populations, Ti-N atom-atom overlap populations, and fragment-charge analysis. DFT calculations on the hydrazido ligand in a mu-eta2, eta1-bridging mode showed involvement of the N=N pi electrons in donation to one of the Ti centers. This TiN2 interaction is best represented as a metallocycle.

Preliminary biological evaluations of new thalidomide analogues for multiple sclerosis application

The present work deals with the synthesis of a new series of thalidomide derivatives for therapeutic applications. These compounds were evaluated in vitro on a human endothelial cell line EA.hy926 for their antiproliferative potential and in vivo on an experimental animal multiple sclerosis model called EAE as angiogenesis inhibitors. The preliminary results obtained on EAE assays seem to validate that anti-angiogenesis compounds could be promising tools for the treatment of MS.

Enantioselective organo-singly occupied molecular orbital catalysis: The carbo-oxidation of styrenes

The first enantioselective organocatalytic carbo-oxidation of styrenes has been accomplished using singly occupied molecular orbital (SOMO) catalysis. Geometrically constrained radical cations are generated from the one-electron oxidation of enamines formed from the condensation of aldehydes with a secondary amine catalyst. These SOMO-activated radical cations are susceptible to attack by commercially available styrenes, forming gamma-oxyaldehyde products with uniformly high levels of asymmetric induction. Broad latitude in both the aldehyde and styrene scope is readily tolerated. This report highlights the potential of SOMO catalysis to enable the development of entirely new classes of asymmetric reactions that have no traditional catalytic equivalents. Copyright

5-(5,6-Dichloro-2-indolyl)-2-methoxy-2,4-pentadienamides: Novel and selective inhibitors of the vacuolar H+-ATPase of osteoclasts with bone antiresorptive activity

The vacuolar H+-ATPase (V-ATPase), located on the ruffled border of the osteoclast, is a proton pump which is responsible for secreting the massive amounts of protons that are required for the bone resorption process. With the aim to identify new agents which are able to prevent the excessive bone resorption associated with osteoporosis, we have designed a novel class of potent and selective inhibitors of the osteoclast proton pump, starting from the structure of the specific V-ATPase inhibitor bafilomycin A1. Compounds 3a-d potently inhibited the V-ATPase in chicken osteoclast membranes (IC50 = 60-180 nM) and were able to prevent bone resorption by human osteoclasts in vitro at low-nanomolar concentrations. Notably, the EC50 of compound 3c in this assay was 45-fold lower than the concentration required for half- maximal inhibition of the V-ATPase from human kidney cortex. These results support the validity of the osteoclast proton pump as a useful molecular target to produce novel inhibitors of bone resorption, potentially useful as antiosteporotic agents.
