Characterization of the conductivity of organic thiols by field emission microscopy and field emission spectroscopy

The conducting properties of two organic thiols (5-mercapto-2,2′-bithiophene and 4-mercaptobiphenyl) deposited by the self-assembly method on Pt tips have been characterized in ultrahigh vacuum by field emission microscopy and spectroscopy. It was shown that these two molecular species can be successfully adsorbed from solution on the Pt tip. The presence of the molecules causes a large decrease in the required field emission voltages by a factor of ～3-5. Measurement of the total energy distributions of the emitted electrons showed that the electrons are emitted from a narrow band which is not pinned at the Fermi level but which shifts to lower energy with increased applied field. The molecules thus appear more like an insulator than a conductor. Significant current-induced heating of the molecules was found: for example, ΔT ≈ 80 K for 0.3 nA. Taken together these properties pose problems for the use of these and similar one-dimensional molecules as current-carrying connections in proposed nanoscale electronic applications. However, when used in the subpicoampere range, the current through the wire may be sustainable and dissipation small. In general, these experiments open a door to exploring other molecules.

Effects of hindered internal rotation on packing and conductance of self-assembled monolayers

Self-assembled monolayers of 4-thiobiphenyl and 2-thiophenanthrene molecules on Au{111} were probed using scanning tunneling microscopy (STM) to investigate their assembled order, to measure the conductance through them, and to determine what molecular features are necessary for molecules to exhibit conductance switching. The 4-thiobiphenyl molecules assemble into two distinct packing structures, whereas no order is observed for 2-thiophenanthrene. Both molecules show rectifying behavior, but although 4-thiobiphenyl is more conductive at positive sample biases, 2-thiophenanthrene is more conductive at negative sample bias. Individual molecules of each type were also inserted into alkanethiol SAMs and tracked over several hours to investigate the conductance states of each molecule. Both molecules exhibit two conductance states, indicating that internal ring rotation is not required for conductance switching.

Synthesis, characterization, and application of palladium-dithizone immobilized on magnetic nanoparticles as an efficient and recoverable catalyst for Suzuki type coupling reactions

A novel, magnetically separable catalyst was synthesized by the immobilization of Pd on magnetite nanoparticles (MNPs) coated with dithizone. The activity of this catalyst was examined for the synthesis of various biaryls via the C-C coupling reaction of aryl halides and sodium tetraphenylborate or phenylboronic acid under mild reaction conditions. Fe3O4/SiO2-DTZ-Pd was characterized by transmission electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, energy dispersive X-ray spectroscopy, vibrating sample magnetometer, and scanning electron microscopy.

Discovery of 3,5-Dimethyl-4-Sulfonyl-1 H-Pyrrole-Based Myeloid Cell Leukemia 1 Inhibitors with High Affinity, Selectivity, and Oral Bioavailability

Myeloid cell leukemia 1 (Mcl-1) protein is a key negative regulator of apoptosis, and developing Mcl-1 inhibitors has been an attractive strategy for cancer therapy. Herein, we describe the rational design, synthesis, and structure-activity relationship study of 3,5-dimethyl-4-sulfonyl-1H-pyrrole-based compounds as Mcl-1 inhibitors. Stepwise optimizations of hit compound 11 with primary Mcl-1 inhibition (52%@30 μM) led to the discovery of the most potent compound 40 with high affinity (Kd = 0.23 nM) and superior selectivity over other Bcl-2 family proteins (>40,000 folds). Mechanistic studies revealed that 40 could activate the apoptosis signal pathway in an Mcl-1-dependent manner. 40 exhibited favorable physicochemical properties and pharmacokinetic profiles (F% = 41.3%). Furthermore, oral administration of 40 was well tolerated to effectively inhibit tumor growth (T/C = 37.3%) in MV4-11 xenograft models. Collectively, these findings implicate that compound 40 is a promising antitumor agent that deserves further preclinical evaluations.
