The synthesis and antibacterial studies of polysubstituted pyrrolo[3,4-b]pyridine derivatives have been described. The preparation of pyrrolo[3,4-b]pyridine derivatives was carried out by the reaction of enamino imides, aromatic aldehydes and malononitrile/ethyl cyanoacetate using 10 mol % of DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) in ethanol at 78 degrees C in good yields. The compounds were characterized by standard spectroscopic techniques including IR, H-1 & C-13 NMR and elemental analysis and also final confirmation was done by single crystal X-ray. The antibacterial activity of all the synthesized compounds was tested against two Gram positive (S. pneumoniae MTCC 655 and E. faecalis MTCC 439) and three Gram negative (E. coli ATCC 25922, S. typhimurium MTCC 3224, and P. aeruginosa MTCC 2453) bacterial strains. Most of the tested compounds showed moderate to good antibacterial activity. Compounds pyrrolo[3,4-b]pyridine derivatives (4 j and 4 l) were the most potent and displayed bactericidal activities against E. coli strain with MIC (minimum inhibitory concentration) values of 62.5 mu g/mL and 125.0 mu g/mL respectively. Growth kinetic studies against E. coli, toxicity studies using human RBCs (red blood cells) and also docking studies of the selected compounds 4 j and 4 l supported that these compounds inhibit the growth of bacterial cells, non-toxic in nature and interact with key amino residues of DNA (deoxyribonucleic acid) duplex (PDBID: 1BNA) and have drug-like properties.

H-1 NMR spectroscopy is a molecular characterization technique that is ubiquitously used in research and teaching laboratories alike. Strategic deuteration of molecules is a commonly employed technique in the deconvolution of H-1 NMR signals. Here this approach is applied in a second-year chemistry course in which students synthesize 4-methoxychalcone using the Claisen-Schmidt variant of the foundational aldol reaction. The H-1 NMR spectrum is complicated by a crowded aromatic and alkene region due in part to extensive conjugation through the two phenyl groups surrounding an alpha,beta-unsaturated ketone. This report demonstrates that students gain competence and confidence in making H-1 NMR assignments when presented with a curated set of selectively deuterated chalcones rather than the corresponding spectrum of the fully protiated chalcone. While deuteration does not resolve all of the challenges associated with interpreting this spectrum, it is an invaluable tool to complement chemical shifts (including the predictive nature of resonance structures), integration, and spin-spin splitting. A proposed lecture is presented that is timed to correlate with the performance of the chalcone synthesis lab. Assessment data collected before and after the lecture and then again on the final exam point to the effectiveness of this approach.

Escherichia coli (E. coli) is recognized as an indicator of fecal bacterial contamination, and the induction of intracellular beta-galactosidase (Gal) is commonly used for sensitive and selective E. coli detection. However, this method requires a permeabilization process to ensure that the Gal substrate and product are highly permeable through the E. coli membrane, making it unsuitable for simple point-of-care detection. Here, we report a sensitive electrochemical method for E. coli detection that does not require a permeabilization process. Intracellular Gal expression is increased via induction by isopropyl-beta-D-thiogalactopyranoside (IPTG). 4-Methoxyphenyl-beta-D-galactopyranoside (MPGP) and 4-methoxyphenol (MP) are used as the highly cell-permeable Gal substrate and product, respectively. Externally-added tyrosinase (Tyr) converts MP into electrochemically active 4-methoxycatechol, which is then electrochemically oxidized via electrochemical-chemical redox cycling involving an electrode, 4-methoxycatechol, and tris(2-carboxyethyl)phosphine. The presence of MPGP during the induction of intracellular Gal led to amplified MP production. The results of four different detection methods using three Gal substrates (MPGP, phenyl-beta-D-galactopyranoside, and 4-aminophenyl-beta-D-galactopyranoside) were compared. The detection limit for both drinking water and tap water spiked with E. coli, obtained following a 2-h-long IPTG treatment and 5-min-long Tyr reaction, was similar to 2 x 10(3) colony-forming units (CFU)/mL, indicating that this method can be applied to monitoring E. coli contamination in water samples. Importantly, the present method does not require the electrode modification, affinity binding, washing, and filtration steps.

Silyl-substituted ketenes are attractive molecular building blocks due to their stability and ease of storage, as opposed to unstable alkyl and aryl ketenes. To better understand the reactivity of silyl ketenes and, in turn, their use in the preparation of highly functionalized small molecules, the reaction of silyl ketenes with different nucleophiles was studied. The addition of alcohol, amine, or thiol nucleophiles to the central carbon of silyl ketene, followed by proton transfer afforded alpha-silyl ester, amide, or thio-ester, respectively. Catalytic amounts of Lewis acid greatly increase the rate of the reaction, and the impact of nucleophile, Lewis acid, and silyl substituent are evaluated. The small molecules produced from these reactions give insight into the use of silyl ketenes as building blocks for complex molecular structures.

Three highly fluorescent perylene bisimide dyes were synthesized, where aromatic ?-system structures are twisted to different degree by steric hindrance of two or four substitution groups at bay position. Light-emitting colours of these dye solutions can be modulated from green, yellow to red, and their fluorescence quantum yields increase up to approximate 100% with increasing the ?-system twisting, which can be considered for new class of wavelength-tunable dye lasers. ?-Twisted dyes are more sensitive to microenvironment changes. Thus, they are better fluorescence probe and sensory materials than planar dyes. Electrochemical cyclic voltammetry measurements revealed that these dyes are suitable for n-type optoelectrical devices and materials. These dye solids display near infra-red emission at 600?850 nm. Owing to strong ?-? stacking interaction, planar dye solid loses its outstanding optical properties compared to its solution. In contrast, ?-twisted dye solids retain their excellent optical properties including narrow emission bands and relatively high fluorescence quantum yields due to the suppression of ?-? stacking interaction. Exceptional fluorescence polarization phenomena were observed for these ?-twisted dye solids. These optical results revealed that ?-twisted perylene bisimide dyes are more excellent optical materials than planar dyes.

N-Chloro-N-(phenylsulfonyl)benzene sulfonamide (NCBSI) has been explored for the first time as a chlorinating reagent for direct chlorination of various activated arenes and heterocycles without any activator. A comparative in-silico study was performed to determine the electrophilic character for NCBSI and commercially available N-chloro reagents to reveal the reactivity on a theoretical viewpoint. The reagent was prepared by an improved method avoiding the use of hazardous t-butyl hypochlorite. This reagent was proved to be very reactive compared to other N-chloro reagents. The precursor of the reagent N-(phenylsulfonyl)benzene sulfonamide was recovered from aqueous spent, which can be recycled to synthesize NCBSI. The eco-friendly protocol was equally applicable for the synthesis of industrially important chloroxylenol as an antibacterial agent. (C) 2020 Elsevier Ltd. All rights reserved.

Twenty-nine nucleoside analogues have been synthesized and evaluated in a cell based assay for their ability to activate the human Stimulator of Interferon Genes (hSTING), a key protein of the innate immune defense. Some 6-O-alkyl nucleoside analogues activate hSTING without associated cytotoxicity. SAR and combination studies were performed to decipher possible activation mechanism. The described nucleoside hSTING activators represent first-in-class modulators of the innate immune defense; a highly relevant target for antiviral, antibacterial, anticancer or Alzheimer’s disease treatments and may present advantages over other types of hSTING activators.

The synthesis of alkylated diazine derivatives is important for their practical utilization as pharmaceuticals and for other purposes. Herein, we describe the metal-free site-selective C-H alkylation of diazine N-oxides using phosphonium ylides that affords a variety of alkylated diazine derivatives with broad functional group tolerance. The utility of this method is showcased by the late-stage functionalization of a commercially available drug such as varenicline. Notably, the sequential C-H alkylation of pyrazine N-oxides for the total synthesis of a pyrazine-containing natural product, paenibacillin A, highlights the importance of this method.
