A new class of tailor-made push-pull isoindole fluorophores has been synthesized through the combination of Suzuki coupling and Knoevenagel reactions. The efficient synthetic strategy rendered the isoindole scaffold as the π-bridge and the isolation spacer and provided dyes bearing various types of electron donors and electron acceptors for manipulating their energy gaps and tuning their absorptions and emissions. Most of the N-alkylated isoindole dyes showed aggregation-induced emission behaviors suitable for bioimaging and nice solid-state emission with maxima up to 851 nm.

Guo, Pu published the artcileCompound shape effects in minor groove binding affinity and specificity for mixed sequence DNA, Name: 4-Bromo-N-butyl-2-nitroaniline, the publication is Journal of the American Chemical Society (2018), 140(44), 14761-14769, database is CAplus and MEDLINE.

AT-specific heterocyclic cations that bind in the DNA duplex minor groove have had major successes as cell and nuclear stains and as therapeutic agents which can effectively enter human cells. Expanding the DNA sequence recognition capability of the minor groove compounds could also expand their therapeutic targets and have an impact in many areas, such as modulation of transcription factor biol. activity. 2268681509. Success in the design of mixed sequence binding compounds has been achieved with N-methylbenzimidazole (N-MeBI) thiophenes which are preorganized to fit the shape of the DNA minor groove and H-bond to the -NH of G·C base pairs that projects into the minor groove. Initial compounds bound strongly to a single G·C base pair in an AT context with a specificity ratio of 50 (K_d AT-GC/K_d AT) or less and this was somewhat low for biol. use. We felt that modifications of compound shape could be used to probe local DNA microstructure in target mixed base-pair sequences of DNA and potentially improve the compound binding selectivity. Modifications were made by increasing the size of the benzimidazole N-substituent, e.g., by using N-iso-Bu instead of N-Me, and by changing the mol. twist by introducing substitutions at specific positions on the aromatic core of the compounds In both cases, we were able to achieve a dramatic increase in binding specificity, including no detectable binding to pure AT sequences, without a significant loss in affinity to mixed base-pair target sequences.

Rene, Olivier published the artcileDiscovery of oxa-sultams as RORc inverse agonists showing reduced lipophilicity, improved selectivity and favorable ADME properties, Computed Properties of 76283-09-5, the publication is Bioorganic & Medicinal Chemistry Letters (2016), 26(18), 4455-4461, database is CAplus and MEDLINE.

Modification of the δ-sultam ring of RORc inverse agonist 2 led to the discovery of more polar oxa-sultam 65. The less lipophilic inverse agonist (65) displayed high potency in a biochem. assay, which translated into inhibition of IL-17 production in human peripheral blood mononuclear cells. The successful reduction of lipophilicity of this new analog gave rise to addnl. improvements in ROR selectivity and aqueous kinetic solubility, as well as reduction in plasma protein binding, while maintaining high cellular permeability.

Touaibia, Mohamed published the artcileStructure-Activity Relationship Studies of New Sinapic Acid Phenethyl Ester Analogues Targeting the Biosynthesis of 5-Lipoxygenase Products: The Role of Phenolic Moiety, Ester Function, and Bioisosterism, HPLC of Formula: 1997-80-4, the publication is Journal of Natural Products (2022), 85(1), 225-236, database is CAplus and MEDLINE.

Sinapic acid is found in many edible plants and fruits, such as rapeseed, where it is the predominant phenolic compound New sinapic acid phenethyl ester (SAPE) analogs were synthesized and screened as inhibitors of the biosynthesis of 5-lipoxygenase (5-LO) in stimulated HEK293 cells and polymorphonuclear leukocytes (PMNL). Inhibition of leukotriene biosynthesis catalyzed by 5-LO is a validated therapeutic strategy against certain inflammatory diseases and allergies. Unfortunately, the only inhibitor approved to date has limited clin. use because of its poor pharmacokinetic profile and liver toxicity. With the new analogs synthesized in this study, the role of the phenolic moiety, ester function, and bioisosterism was investigated. Several of the 34 compounds inhibited the biosynthesis of 5-LO products, and 20 compounds were 2-11 times more potent than zileuton in PMNL, which are important producers of 5-LO products. Compounds 5i (I)(IC₅₀: 0.20 μM), 5l (II) (IC₅₀: 0.20 μM), and 5o (III)(IC₅₀: 0.21 μM) bearing 4-trifluoromethyl, Me, or methoxy substituent at meta-position of the phenethyl moiety were 1.5 and 11.5 times more potent than SAPE (IC₅₀: 0.30 μM) and zileuton (IC₅₀: 2.31 μM), resp. Addnl., compound 9 (IC₅₀: 0.27 μM), which was obtained after acetylation of the 4-hydroxyl of SAPE, was equivalent to SAPE and 8 times more active than zileuton. Furthermore, compound 20b (IV) (IC₅₀: 0.27 μM) obtained after the bioisosteric replacement of the ester function of SAPE by the 1,2,4-oxadiazole heterocycle was equivalent to SAPE and 8 times more active than zileuton. Thus, this study provides a basis for the rational design of new mols. that could be developed further as anti 5-LO therapeutics.

Kancharla, Papireddy published the artcileLead Optimization of Second-Generation Acridones as Broad-Spectrum Antimalarials, Recommanded Product: (4-(Bromomethyl)phenyl)(trifluoromethyl)sulfane, the publication is Journal of Medicinal Chemistry (2020), 63(11), 6179-6202, database is CAplus and MEDLINE.

The global impact of malaria remains staggering despite extensive efforts to eradicate the disease. With increasing drug resistance and the absence of a clin. available vaccine, there is an urgent need for novel, affordable, and safe drugs for prevention and treatment of malaria. Previously, we described a novel antimalarial acridone chemotype that is potent against both blood-stage and liver-stage malaria parasites. Here, we describe an optimization process that has produced a second-generation acridone series with significant improvements in efficacy, metabolic stability, pharmacokinetics, and safety profiles. These findings highlight the therapeutic potential of dual-stage targeting acridones as novel drug candidates for further preclin. development.

The β-D isotope effects on the C-13 chem. shifts of 2,3-dimethyl-2-butene, 2,3-dimethyl-2-butene bromonium ion, and 2,3-dimethyl-2-butene mercurinium ion suggests that these cationic derivatives have different electronic structures. The β-D isotope effect in the bromonium ion is pos. (downfield shift) while that in the mercurinium ion is neg. (upfield shift). A comparison with β-D isotope shifts in other cations suggests that the β effects can be related to the electronic structure of these ions.

Yu, Yingjian published the artcileA p-π* conjugated triarylborane as an alcohol-processable n-type semiconductor for organic optoelectronic devices, Recommanded Product: 2-Bromo-3-(2-ethylhexyl)thiophene, the publication is Journal of Materials Chemistry C: Materials for Optical and Electronic Devices (2019), 7(24), 7427-7432, database is CAplus.

A p-π* conjugated organic mol. based on triarylborane is reported as n-type organic semiconductor with unique alc. solubility Its favorable alc. solubility even in the absence of polar side chains is mainly due to the large dipole moment and enhanced flexibility of the conjugated backbone once the boron atom is embedded. The p-π* conjugation directly affects the electronic structure as the LUMO is fully delocalized, including the boron atom, whereas the HOMO has the boron atom residing on a node. As a result, the mol. exhibits low-lying LUMO/HOMO energy levels of -3.61 eV/-5.73 eV paired with a good electron mobility of 1.37 × 10^-5 cm² V^-1 s^-1. Its application as an electron acceptor is demonstrated in alc.-processed organic solar cells (OSCs). This p-π* conjugated mol. is the first alc.-processable non-fullerene electron acceptor, a feature that is in strong demand for environmentally friendly processing of OSCs.

Khudozhitkov, Alexander E. published the artcileHigh-Temperature Quantum Tunneling and Hydrogen Bonding Rearrangements Characterize the Solid-Solid Phase Transitions in a Phosphonium-Based Protic Ionic Liquid, Name: 1-Bromooctane, the publication is Chemistry – A European Journal (2022), 28(23), e202200257, database is CAplus and MEDLINE.

Authors report the complex phase behavior of the glass forming protic ionic liquid (PIL) d3-octylphosphonium bis(trifluoromethylsulfonyl)imide [C₈H₁₇PD₃][NTf₂] by solid-state NMR spectroscopy. Combined line shape and spin relaxation studies of the deuterons in the PD₃ group of the octylphosphonium cation allow to map and correlate the phase behavior for a broad temperature range from 71 K to 343 K. In the solid PIL at 71 K, we observed a static state, characterized by the first deuteron quadrupole coupling constant reported for PD₃ deuterons. A transition enthalpy of about 12 kJ mol^-1 from the static to the mobile state with increasing temperature suggests the breaking of a weak, charge-enhanced hydrogen bond between cation and anion. The highly mobile phase above 100 K exhibits an almost disappearing activation barrier, strongly indicating quantum tunneling. Thus, they provide first evidence of tunneling driven mobility of the hydrogen bonded P-D moieties in the glassy state of PILs, already at surprisingly high temperatures up to 200 K. Above 250 K, the mobile phase turns from anisotropic to isotropic motion, and indicates strong internal rotation of the PD₃ group. The analyzed line shapes and spin relaxation times allow us to link the structural and dynamical behavior at mol. level with the phase behavior beyond the DSC traces.
