Park, Sohyun published the artcileValidating the Mott Formula with Self-Assembled Monolayer (SAM)-Based Large-Area Junctions: Effect of Length, Backbone, Spacer, Substituent, and Electrode on the Thermopower of SAMs, Formula: C8H10S, the publication is Journal of Physical Chemistry C (2021), 125(36), 20035-20047, database is CAplus.

Understanding how the Seebeck effect of organic thermoelec. devices is associated with the chem. structure of active mols. within the devices is a key goal in organic and mol. thermoelecs. This paper describes a series of phys.-organic studies that investigate structure-thermopower relationships in self-assembled monolayers (SAMs) through measurements of the Seebeck coefficient (S, μV/K) using the eutectic gallium-indium (EGaIn)-based junction technique. Several hypotheses were derived from a transmission function-based simple toy model, the Lorentzian transmission function-based Mott formula. These hypotheses were tested by comparing values of S for simple alkyl and aryl mols. with different structures in terms of backbone, length, spacer, anchor, and substituent, and for different electrodes (Au vs Ag), and by monitoring responses of S to the structural modifications. Exptl. obtained S values were further reconciled with values simulated by the Mott formula and with interfacial electronic structure and mol.-electrode coupling strength, independently measured by UPS and transition voltage spectroscopy.

Santhakumari, Sivasubramanian published the artcileIn vitro and in vivo effect of 2,6-Di-tert-butyl-4-methylphenol as an antibiofilm agent against quorum sensing mediated biofilm formation of Vibrio spp., Formula: C6H13NO2, the publication is International Journal of Food Microbiology (2018), 60-71, database is CAplus and MEDLINE.

This study unveils the in vitro and in vivo antibiofilm potential of 2,6-Di-tert-butyl-4-methylphenol (DTBMP) from Chroococcus turgidus against Vibrio spp. In the preliminary study, cell free culture supernatant (CFCS) of C. turgidus inhibited the violacein production in biomarker strain Chromobacterium violaceum and its mutant strain CV026 in a dose dependent manner. The effective biofilm inhibitory concentration (BIC) of pure compound DTBMP from C. turgidus was identified as 250μg/mL concentration in tested Vibrio species. Furthermore, DTBMP proved to effectively inhibit the bioluminescence production in V. harveyi and other biofilm related virulence traits such as exopolysaccharides (EPS) production, hydrophobicity index, swimming and swarming motility at its BIC concentration in three major pathogenic vibrios: V. harveyi, V. parahaemolyticus and V. vulnificus. The antibiofilm potential of DTBMP was validated through light, confocal laser scanning and scanning electron microscopic analyses. In addition, the non-bactericidal effect of DTBMP was determined through growth curve and 2,3-bis (2-methyloxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) assay. Real-time PCR studies revealed the down-regulation of master quorum sensing (QS) regulator genes of V. harveyi such as luxR, luxS, luxP, luxQ and luxO on treatment with DTBMP. In vivo results confirmed that DTBMP augmented the survival rate of Litopenaeus vannamei larvae up to 75, 88 and 66% upon infection with V. harveyi, V. parahaemolyticus and V. vulnificus, resp. The results of this study ascertain the promising effects of DTBMP as an antibiofilm agent, which could be pos. explored to treat biofilm-associated vibrios infections in aquaculture.

Miller, Eric J. published the artcileDiscovery of Tetrahydroisoquinoline-Containing CXCR4 Antagonists with Improved in Vitro ADMET Properties, HPLC of Formula: 6346-09-4, the publication is Journal of Medicinal Chemistry (2018), 61(3), 946-979, database is CAplus and MEDLINE.

CXCR4 is a seven-transmembrane receptor expressed by hematopoietic stem cells and progeny, as well as by ≥48 different cancers types. CXCL12, the only chemokine ligand of CXCR4, is secreted within the tumor microenvironment, providing sanctuary for CXCR4⁺ tumor cells from immune surveillance and chemotherapeutic elimination by (1) stimulating prosurvival signaling and (2) recruiting CXCR4⁺ immunosuppressive leukocytes. Addnl., distant CXCL12-rich niches attract and support CXCR4⁺ metastatic growths. Accordingly, CXCR4 antagonists can potentially obstruct CXCR4-mediated prosurvival signaling, recondition the CXCR4⁺ leukocyte infiltrate from immunosuppressive to immunoreactive, and inhibit CXCR4⁺ cancer cell metastasis. Current small mol. CXCR4 antagonists suffer from poor oral bioavailability and off-target liabilities. Herein, we report a series of novel tetrahydroisoquinoline-containing CXCR4 antagonists designed to improve intestinal absorption and off-target profiles. Structure-activity relationships regarding CXCR4 potency, intestinal permeability, metabolic stability, and cytochrome P 450 inhibition are presented.

Heuckendorff, Mads published the artcileDIDMH in combination with triflic acid – A new promoter system for thioglycoside glycosyl donors, Product Details of C12H20O6, the publication is Carbohydrate Research (2018), 86-91, database is CAplus and MEDLINE.

We have explored the possibility of using 1,3-diiodo-5,5-dimethylhydantoin (DIDMH) as an alternative to N-iodosuccinimide (NIS) for activation of glycosyl donors of the thioglycoside type in various glycosylation reactions. DIDMH was found to match NIS when it comes to the capability to activate thioglycosides and provide glycosylation products in good yields. Notably, with the two equivalent of reactive iodonium ions per mol. of DIDMH less mass needs to be added making this activator a more atom economically alternative to NIS. Furthermore, DIDMH was found to be stable upon storage for weeks and comparably priced to NIS. With this knowledge in hand we therefore encourage the carbohydrate community to consider using DIDMH for activation of thioglycosides in glycosylation reactions.

Ko, Young Ok published the artcileRh(II)/Mg(O^tBu)₂-Catalyzed Tandem One-Pot Synthesis of 1,4-Oxazepines and 1,4-Oxazines from N-Sulfonyl-1,2,3-triazoles and Glycidols, Related Products of alcohols-buliding-blocks, the publication is Organic Letters (2016), 18(24), 6432-6435, database is CAplus and MEDLINE.

A novel, one-pot route for the synthesis of nonaromatic ring-fused 1,4-oxazepines and 1,4-oxazines has been developed. The reaction features a sequential rhodium(II)-catalyzed reaction of N-sulfonyl-1,2,3-triazoles with glycidols, followed by a regioselective Lewis acid Mg(O^tBu)₂-catalyzed intramol. ring-opening reaction. It has been found that the regioselectivity in the epoxide ring-opening was largely determined by the substituents on the glycidols. Thus, substituted glycidols I (R² ≠ H) afforded seven-membered oxazepine derivatives selectively, e.g. II, while unsubstituted glycidols I (R² = H) afforded six-membered oxazine derivatives, e.g. III. Plausible reaction pathways are elucidated and supported by experiments with several glycidols bearing different substituents around the epoxide functionality.
