Park, Kwang-Won published the artcileLarge-Area Heteroepitaxial Nanostructuring of Molecular Semiconductor Films for Enhanced Optoelectronic Response in Flexible Electronics, Recommanded Product: Coronene, the publication is Advanced Functional Materials (2022), 32(22), 2113085, database is CAplus.

Organized nano- and microstructures of mol. semiconductors display interesting optical and photonic properties, and enhanced charge carrier mobilities, as compared to disordered thin films. However, known directed-growth and self-organization strategies cannot create structured mol. heterojunctions and cannot be practically incorporated into existing device fabrication routines to create large-area optoelectronic devices. Here, an ultrathin (<2 nm) seed layer of the compound coronene creates 1D nanostructures of an electron-transporting mol. (IFD) is shown, which possesses an intrinsic proclivity to form disordered thin films in the absence of the seed layer. It is revealed that nanostructured IFD films exhibit enhanced light absorption and emission, and greater electron mobilities, as compared to amorphous counterparts. This seed layer strategy creates uniform IFD nanowires over large areas of up to 18 mm2 at low processing temperatures Notably, the coronene seed layer creates IFD nanowires when applied over either oxide surfaces or predeposited organic layers, meaning that this structuring approach can be integrated into diode manufacturing routines to realize large-area flexible optoelectronic devices. Flexible organic light-emitting diodes and fullerene-free organic solar cells containing IFD nanowires in the photoactive layer to demonstrate that mol. nanostructures can lead to robust, large-area device arrays on flexible substrates being fabricated.

The synthesis and pharmacol. evaluation of a new scaffold with antagonistic activity for NMDAR was reported. Specifically, a chem. library of eighteen 1-aminoindan-2-ol tetracyclic lactams was synthesized and screened as NMDAR antagonists. The compounds were obtained by chiral pool synthesis using enantiomerically pure 1-aminoindan-2-ols as chiral inductors, and their stereochem. was proven by X-ray crystallog. anal. of two target compounds Most compounds reveal NMDAR antagonism, and eleven compounds display IC50 values in a Ca2+ entry-sensitive fluo-4 assay in the same order of magnitude of memantine, a clin. approved NMDAR antagonist. Docking studies suggest that the novel compounds can act as NMDAR channel blockers since there is a compatible conformation with MK-801 co-crystallized with NMDAR channel. In addition, we show that the tetracyclic 1-aminoindan-2-ol derivatives are brain permeable and non-toxic, and we identify promising hits for further optimization as modulators of the NMDAR function.

We report on high-energy terahertz pulses by optical rectification (OR) in the organic crystal N-benzyl-2-methyl-4-nitroaniline (BNA) directly pumped by a conventional Ti:sapphire amplifier. The simple scheme provides an optical-to-terahertz conversion efficiency of 0.25% when pumped by collimated laser pulses with duration of 50 fs and a central wavelength of 800 nm. The generated radiation spans frequencies between 0.2 and 3 THz. We measured the damage threshold, as well as the dependency of the conversion efficiency on the pump fluence, pump wavelength, and pulse duration.

Photolariat development, as an extension to the family of synthetic photochromic crown ether receptors, or photocrowns, is reported. Incorporated addnl. chelating groups, namely two anisoles or thioanisoles, contribute in completing the metal ion coordination sphere with different affinities and selectivities for a range of ions. Single-crystal X-ray diffraction anal. suggests that the thermally stable trans-form of the receptor is unsuitable for ion binding, consistent with spectrophotometric and NMR titration results, which is largely improved in the cis-form as the basis for the photocontrolled ion coordination/ejection. In terms of the azobenzene-containing receptor photochem., a photostationary state highly enriched in the cis-form (94:6, cis-/trans-) is reached, with slow thermal return (1.1-1.4 ¡Á 10?5 s?1) in the dark, which can undergo multiple cycles without discernable photodegradation

An HPLC method is used to detect and determine Ph2NH and its reaction products with NOx, especially in respect to the anal. of single-base propellants. Polygosil 100 C 18 is the packing material, the maximum injection volume of CH2Cl2 is 2 ¦ÌL, and the eluent is 10:40:50 MeOH-MeCN-H2O; detection is done at 210 nm. Normal-phase chromatog. can be used in the separation of Ph2NH and 2,4,4′-trinitrodiphenylamine, but, in most propellant analyses, retains 4,4′-dinitrodiphenylamine (a major reaction product) excessively. Reversed-phase chromatog. has the advantages of short equilibration time, separating ability for both polar and nonpolar solutes, and good reproducibility of retention times.

Four new complexes of Cu(II) of stoichiometry [Cu(ATP)(polyamine)] containing polyamines (PA) ethylenediamine, 1,3-diaminopropane, spermidine, or spermine and ATP were prepared from aqueous solution at pH 6. Synthesis, characterization, thermogravimetric, vibrational spectroscopy, and ESR analyses are described and show that these complexes have similar mol. structures. IR spectra and the thermal anal. are briefly discussed based on the peculiarities of the complexes. The IR spectra of the ligands and their copper complexes were used to assign the various groups and compare the shifts due to complexation. ESR parameters values for the complexes show that Cu(II) is complexed in a similar way in the four complexes. Similarity in the coordination mode of complexes in solid state has been determined and discussed. The data obtained suggest that the four complexes contain one water mol. of hydration and are complexed through two oxygen atoms from ATP and through two nitrogen atoms of each polyamine.

Dewangan, Rikeshwer Prasad’s team published research in Journal of Medicinal Chemistry in 65 | CAS: 71989-31-6

Journal of Medicinal Chemistry published new progress about 71989-31-6. 71989-31-6 belongs to catalysis-chemistry, auxiliary class Amino acide derivatives,pyrrolidine, name is Fmoc-Pro-OH, and the molecular formula is C20H19NO4, Synthetic Route of 71989-31-6.

Dewangan, Rikeshwer Prasad published the artcileSpermine-conjugated short proline-rich lipopeptides as broad-spectrum intracellular targeting antibacterial agents, Synthetic Route of 71989-31-6, the publication is Journal of Medicinal Chemistry (2022), 65(7), 5433-5448, database is CAplus and MEDLINE.

Toward the design of new proline-rich peptidomimetics, a short peptide segment, present in several proline-rich antimicrobial peptides (AMPs), was selected. Fatty acids of varying lengths and spermine were conjugated at the N- and C-terminals of the peptide, resp. Spermine-conjugated lipopeptides, C10-PR-Spn and C12-PR-Spn, exhibited min. inhibitory concentrations within 1.5-6.2¦ÌM against the tested pathogens including resistant bacteria and insignificant hemolytic activity against human red blood cells up to 100¦ÌM concentrations and demonstrated resistance against trypsin digestion. C10-PR-Spn and C12-PR-Spn showed synergistic antimicrobial activity against multidrug-resistant methicillin-resistant Staphylococcus aureus with several tested antibiotics. These lipopeptides did not permeabilize bacterial membrane-mimetic lipid vesicles or damage the Escherichia coli membrane like the nonmembrane-lytic AMP, buforin-II. The results suggested that C10-PR-Spn and C12-PR-Spn could interact with the 70S ribosome of E. coli and inhibit its protein synthesis. C10-PR-Spn and C12-PR-Spn demonstrated superior clearance of bacteria from the spleen, liver, and kidneys of mice, infected with S. aureus ATCC 25923 compared to levofloxacin.
